Commit e519f0bb64 ("ARM/mmc: Convert old mmci-omap to GPIO descriptors")
moved Nokia N810 MMC power up/down from the board file into the MMC driver.
The change removed some delays, and ordering without a valid reason.
Restore power up/down to match the original code. This matters only on N810
where the 2nd GPIO is in use. Other boards will see an additional delay but
that should be a lesser concern than omitting delays altogether.

Parsing dt usually happens very early, sometimes even before the struct
mmc_host has been allocated (e.g. dw_mci_probe() and dw_mci_parse_dt() in
dw_mmc.c). Looking at the source of mmc_of_parse_clk_phase(), it's actually
not needed to have an initialized mmc_host, let's therefore pass a struct
device* to it instead.
Also update the only current user, sdhci-of-aspeed.

With the to-be-fixed commit, the reset_work handler cleared 'host->mrq'
outside of the spinlock protected critical section. That leaves a small
race window during execution of 'tmio_mmc_reset()' where the done_work
handler could grab a pointer to the now invalid 'host->mrq'. Both would
use it to call mmc_request_done() causing problems (see link below).
However, 'host->mrq' cannot simply be cleared earlier inside the
critical section. That would allow new mrqs to come in asynchronously
while the actual reset of the controller still needs to be done. So,
like 'tmio_mmc_set_ios()', an ERR_PTR is used to prevent new mrqs from
coming in but still avoiding concurrency between work handlers.

AC5X spec says PHY init complete bit must be polled until zero.
We see cases in which timeout can take longer than the standard

According to the spec, we must wait as long as it takes for that bit to
toggle on AC5X.
Cap that with 100 delay loops so we won't get stuck forever.

The introduction of sg_miter was a bit sloppy as it didn't
exactly mimic the semantics of the old code on multiblock reads
and writes: these like you to:
- Advance to the first sglist entry *before* starting to read
any blocks from the card.
- Advance and check availability of the next entry *right after*
processing one block.
Not checking if we have more sglist entries right after
reading a block will lead to this not being checked until we
return to the callback to read out more blocks, i.e. until the
next interrupt arrives. Since the last block is the last one
(no more data will arrive) there will not be a next interrupt,
and we will be waiting forever resulting in a timeout for
command 18 when reading multiple blocks.
The same bug was fixed also in the writing of multiple blocks.

The sg_miter used to loop over the returned sglist from a
transfer in the esdhc subdriver for SDHCI can be called
from atomic context so the miter needs to be atomic.
sdhci_request_done() is always called from process context,
either as a work or as part of the threaded interrupt handler,
but the one case when we are actually calling .request_done()
from an atomic context is in sdhci_irq().
Fix this by flagging the miter atomic so we always use
kmap_atomic().

Use the scatterlist memory iterator instead of just
dereferencing virtual memory using sg_virt().
This make highmem references work properly.
This driver also has a bug in the PIO sglist handling that
is fixed as part of the patch: it does not travers the
list of scatterbuffers: it will just process the first
item in the list. This is fixed by augmenting the logic
such that we do not process more than one sgitem
per IRQ instead of counting down potentially the whole
length of the request.
We can suspect that the PIO path is quite untested.

The whole scatterlist chain is submitted to the DMA engine,
but the code is written to just account for the length of
the first sg entry.
When the DMA transfer is finished, all the data in the
request has been transferred, account for this instead.
This only works because the moxart_request() function isn't
checking that all data was transferred and will
unconditionally issue mmc_request_done() after returning
successfully from moxart_transfer_dma().
Keep the assignment of accounted bytes in .bytes_xfered
but move it after the completion where we know it has
actually happened.

The MMC core sets BLK_BOUNCE_HIGH for devices where dma_mask
is unassigned.
For the majority of MMC hosts this path is never taken: the
OF core will unconditionally assign a 32-bit mask to any
OF device, and most MMC hosts are probed from device tree,
see drivers/of/platform.c:
of_platform_device_create_pdata()
dev->dev.coherent_dma_mask = DMA_BIT_MASK(32);
if (!dev->dev.dma_mask)
dev->dev.dma_mask = &dev->dev.coherent_dma_mask;
of_amba_device_create()
dev->dev.coherent_dma_mask = DMA_BIT_MASK(32);
dev->dev.dma_mask = &dev->dev.coherent_dma_mask;
MMC devices that are probed from ACPI or PCI will likewise
have a proper dma_mask assigned.
The only remaining devices that could have a blank dma_mask
are platform devices instantiated from board files.
These are mostly used on systems without CONFIG_HIGHMEM
enabled which means the block layer will not bounce, and in
the few cases where it is enabled it is not used anyway:
for example some OMAP2 systems such as Nokia n800/n810 will
create a platform_device and not assign a dma_mask, however
they do not have any highmem, so no bouncing will happen
anyway: the block core checks if max_low_pfn >= max_pfn
and this will always be false.
Should it turn out there is a platform_device with blank
DMA mask actually using CONFIG_HIGHMEM somewhere out there
we should set dma_mask for it, not do this trickery.

A moderately busy release for SPI, the main core update was the merging
of support for multiple chip selects, used in some flash configurations.
There were also big overhauls for the AXI SPI Engine and PL022 drivers,
plus some new device support for ST.
There's a few patches for other trees, API updates to allow the
multiple chip select support and one of the naming modernisations
touched a controller embedded in the USB code.
- Support for multiple chip selects.
- A big overhaul for the AXI SPI engine driver, modernising it and
adding a bunch of new features.
- Modernisation of the PL022 driver, fixing some issues with submitting
messages while in atomic context in the process.
- Many drivers were converted to use new APIs which avoid outdated
terminology for devices and controllers.
- Support for ST Microelectronics STM32F7 and STM32MP25, and Renesas

Merge tag 'spi-v6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown:
"A moderately busy release for SPI, the main core update was the
merging of support for multiple chip selects, used in some flash
configurations. There were also big overhauls for the AXI SPI Engine
and PL022 drivers, plus some new device support for ST.
There's a few patches for other trees, API updates to allow the
multiple chip select support and one of the naming modernisations
touched a controller embedded in the USB code.
- Support for multiple chip selects.
- A big overhaul for the AXI SPI engine driver, modernising it and
adding a bunch of new features.
- Modernisation of the PL022 driver, fixing some issues with
submitting messages while in atomic context in the process.
- Many drivers were converted to use new APIs which avoid outdated
terminology for devices and controllers.
- Support for ST Microelectronics STM32F7 and STM32MP25, and Renesas

AC5/X/IM SOCs has a variant of the Xenon eMMC controller,
in which only 31-bit of addressing pass from the controller
on the AXI bus.
Since we cannot guarantee that only buffers from the first 2GB
of memory will reach the driver, the driver is configured for
SDMA mode, without 64-bit mode, overriding the DMA mask to 34-bit
to support the DDR memory mapping, which starts at offset 8GB.

Requesting a retune before switching to the RPMB partition has been
observed to cause CRC errors on the RPMB reads (-EILSEQ).
Since RPMB reads can not be retried, the clients would be directly
affected by the errors.
This commit disables the retune request prior to switching to the RPMB
partition: mmc_retune_pause() no longer triggers a retune before the
pause period begins.
This was verified with the sdhci-of-arasan driver (ZynqMP) configured
for HS200 using two separate eMMC cards (DG4064 and 064GB2). In both
cases, the error was easy to reproduce triggering every few tenths of
reads.
With this commit, systems that were utilizing OP-TEE to access RPMB
variables will experience an enhanced performance. Specifically, when
OP-TEE is configured to employ RPMB as a secure storage solution, it not
only writes the data but also the secure filesystem within the
partition. As a result, retrieving any variable involves multiple RPMB
reads, typically around five.
For context, on ZynqMP, each retune request consumed approximately
8ms. Consequently, reading any RPMB variable used to take at the very
minimum 40ms.
After droping the need to retune before switching to the RPMB partition,
this is no longer the case.

There is no need to duplicate what SPI core or individual controller
drivers already do, i.e. mapping the buffers for DMA capable transfers.
Note, that the code, besides its redundancy, was buggy: strictly speaking
there is no guarantee, while it's true for those which can use this code
(see below), that the SPI host controller _is_ the device which does DMA.
Also see the Link tags below.
Additional notes. Currently only two SPI host controller drivers may use
premapped (by the user) DMA buffers:
- drivers/spi/spi-au1550.c
- drivers/spi/spi-fsl-spi.c
Both of them have DMA mapping support code. I don't expect that SPI host
controller code is worse than what has been done in mmc_spi. Hence I do
not expect any regressions here. Otherwise, I'm pretty much sure these
regressions have to be fixed in the respective drivers, and not here.
That said, remove all related pieces of DMA mapping code from mmc_spi.

Previously, during the MSDC calibration process, a full clock cycle
actually not be covered, which in some cases didn't yield the best
results and could cause CRC errors. This problem is particularly
evident when MSDC is used as an SDIO host. In fact, MSDC support
tuning up to a maximum of 64 steps, but by default, the step number
is 32. By increase the tuning step, we are more likely to cover more
parts of a clock cycle, and get better calibration result.
To illustrate, when tuning 32 steps, if the obtained window has a hole
near the middle, like this: 0xffc07ff (hex), then the selected delay
will be the 6 (counting from right to left).
(32 <- 1)
1111 1111 1100 0000 0000 0111 11(1)1 1111
However, if we tune 64 steps, the window obtained may look like this:
0xfffffffffffc07ff. The final selected delay will be 44, which is
safer as it is further away from the hole:
(64 <- 1)
1111 ... (1)111 1111 1111 1111 1111 1100 0000 0000 0111 1111 1111
In this case, delay 6 selected through 32 steps tuning is obviously
not optimal, and this delay is closer to the hole, using it would
easily cause CRC problems.
As per mesaurements taken on mediatek SoC platform, the tuning phase
will take:
eMMC - 32 steps: ~3ms
- 64 steps: ~6ms
SDIO - 32 steps: ~4ms
- 64 steos: ~7ms
Tuning more steps won't prolong boot times by any meaningful amount
of time, so for SD/SDIO the default tuning steps will be adjust to
64. But for eMMC, it is still preferred to use 32 steps tuning as
otherwise there would be performance lose when accessing the RPMB
partition(requiring retuning each time).
You can configure property "mediatek,tuning-step" in MSDC dts node
to adjust the step number.

Field Firmware Update (ffu) may use close-ended or open ended sequence.
Each such sequence is comprised of a write commands enclosed between 2
switch commands - to and from ffu mode. So for the close-ended case, it
will be: cmd6->cmd23-cmd25-cmd6.
Some host controllers however, get confused when multi-block rw is sent
without sbc, and may generate auto-cmd12 which breaks the ffu sequence.
I encountered this issue while testing fwupd (github.com/fwupd/fwupd)
on HP Chromebook x2, a qualcomm based QC-7c, code name - strongbad.
Instead of a quirk, or hooking the request function of the msm ops,
it would be better to fix the ioctl handling and make it use mrq.sbc

limited LPM negotiation to runtime suspend state.
The problem is that it only flips the switch in the runtime PM
resume/suspend logic.
Disable LPM negotiation in gl9763e_add_host.
This helps in two ways:
1. It was found that the LPM switch stays in the same position after
warm reboot. Having it set in init helps with consistency.
2. Disabling LPM during the first runtime resume leaves us susceptible
to the performance issue in the time window between boot and the
first runtime suspend.

If a task completion notification (TCN) is received when there is no
outstanding task, the cqhci driver issues a "spurious TCN" warning. This
was observed to happen right after CQE error recovery.
When an error interrupt is received the driver runs recovery logic.
It halts the controller, clears all pending tasks, and then re-enables
it. On some platforms, like Intel Jasper Lake, a stale task completion
event was observed, regardless of the CQHCI_CLEAR_ALL_TASKS bit being set.
This results in either:
a) Spurious TC completion event for an empty slot.
b) Corrupted data being passed up the stack, as a result of premature
completion for a newly added task.
Rather than add a quirk for affected controllers, ensure tasks are cleared
by toggling CQHCI_ENABLE, which would happen anyway if
cqhci_clear_all_tasks() timed out. This is simpler and should be safe and
effective for all controllers.

During board verification, there is a need to test the various supported
eMMC/SD speed modes. However, since the framework chooses the best mode
supported by the card and the host controller's caps, this currently
necessitates changing the devicetree for every iteration.
Allow the various speed mode host capabilities to be modified via
debugfs in order to allow easier hardware verification. The values to
be written are the raw MMC_CAP* values from include/linux/mmc/host.h.
This is rather low-level, and these defines are not guaranteed to be
stable, but it is perhaps good enough for the intended use case.
MMC_CAP_AGGRESSIVE_PM can also be set, in order to be able to
re-initialize the card without having to physically remove and re-insert
it.

The OEMID is an 8-bit binary number rather than 16-bit as the current code
parses for. The OEMID occupies bits [111:104] in the CID register, see the
eMMC spec JESD84-B51 paragraph 7.2.3. It seems that the 16-bit comes from
the legacy MMC specs (v3.31 and before).
Let's fix the parsing by simply move to use 8-bit instead of 16-bit. This
means we ignore the impact on some of those old MMC cards that may be out
there, but on the other hand this shouldn't be a problem as the OEMID seems
not be an important feature for these cards.

By dynamically adjusting the host->hsq_depth, based upon the buffer size
being 4k and that we get at least two I/O write requests in flight, we can
improve the throughput a bit. This is typical for a random I/O write
pattern.
More precisely, by dynamically changing the number of requests in flight
from 2 to 5, we can on some platforms observe ~4-5% increase in throughput.

Userspace has currently no way of checking the internal R1 response error
bits for some commands. This is a problem for some commands, like RPMB for
example. Typically, we may detect that the busy completion has successfully
ended, while in fact the card did not complete the requested operation.
To fix the problem, let's always poll with CMD13 for these commands and
during the polling, let's also aggregate the R1 response bits. Before
completing the ioctl request, let's propagate the R1 response bits too.

To improve the r/w performance of GL9763E, the current driver inhibits LPM
negotiation while the device is active.
This prevents a large number of SoCs from suspending, notably x86 systems
which commonly use S0ix as the suspend mechanism - for example, Intel
Alder Lake and Raptor Lake processors.
Failure description:
1. Userspace initiates s2idle suspend (e.g. via writing to
/sys/power/state)
2. This switches the runtime_pm device state to active, which disables
LPM negotiation, then calls the "regular" suspend callback
3. With LPM negotiation disabled, the bus cannot enter low-power state
4. On a large number of SoCs, if the bus not in a low-power state, S0ix
cannot be entered, which in turn prevents the SoC from entering
suspend.
Fix by re-enabling LPM negotiation in the device's suspend callback.

- cpm_uart driver updates
- n_gsm updates and fixes
- meson driver updates
- sc16is7xx driver updates
- 8250 driver updates for different hardware types
- qcom-geni driver fixes
- tegra serial driver change
- stm32 driver updates
- synclink_gt driver cleanups
- tty structure size reduction
All of these have been in linux-next this week with no reported issues.
The last bit of cleanups from Jiri and the tty structure size reduction
came in last week, a bit late but as they were just style changes and
size reductions, I figured they should get into this merge cycle so that
others can work on top of them with no merge conflicts.

Summary of the changes worth highlighting from most interesting to boring below:
* Christoph Hellwig's symbol_get() fix to Nvidia's efforts to circumvent the
protection he put in place in year 2020 to prevent proprietary modules from
using GPL only symbols, and also ensuring proprietary modules which export
symbols grandfather their taint. That was done through year 2020 commit
262e6ae708 ("modules: inherit TAINT_PROPRIETARY_MODULE"). Christoph's new
fix is done by clarifing __symbol_get() was only ever intended to prevent
module reference loops by Linux kernel modules and so making it only find
symbols exported via EXPORT_SYMBOL_GPL(). The circumvention tactic used
by Nvidia was to use symbol_get() to purposely swift through proprietary
module symbols and completley bypass our traditional EXPORT_SYMBOL*()
annotations and community agreed upon restrictions.
A small set of preamble patches fix up a few symbols which just needed
adjusting for this on two modules, the rtc ds1685 and the networking enetc
module. Two other modules just needed some build fixing and removal of use
of __symbol_get() as they can't ever be modular, as was done by Arnd on
the ARM pxa module and Christoph did on the mmc au1xmmc driver.
This is a good reminder to us that symbol_get() is just a hack to address
things which should be fixed through Kconfig at build time as was done in
the later patches, and so ultimately it should just go.
* Extremely late minor fix for old module layout 055f23b74b ("module: check
for exit sections in layout_sections() instead of module_init_section()") by
James Morse for arm64. Note that this layout thing is old, it is *not*
Song Liu's commit ac3b432839 ("module: replace module_layout with
module_memory"). The issue however is very odd to run into and so there was
no hurry to get this in fast.
* Although the fix did not go through the modules tree I'd like to highlight
the fix by Peter Zijlstra in commit 5409730962 ("x86/static_call: Fix
__static_call_fixup()") now merged in your tree which came out of what
was originally suspected to be a fallout of the the newer module layout
changes by Song Liu commit ac3b432839 ("module: replace module_layout
with module_memory") instead of module_init_section()"). Thanks to the report
by Christian Bricart and the debugging by Song Liu & Peter that turned to
be noted as a kernel regression in place since v5.19 through commit
ee88d363d1 ("x86,static_call: Use alternative RET encoding").
I highlight this to reflect and clarify that we haven't seen more fallout
from ac3b432839 ("module: replace module_layout with module_memory").
* RISC-V toolchain got mapping symbol support which prefix symbols with "$"
to help with alignment considerations for disassembly. This is used to
differentiate between incompatible instruction encodings when disassembling.
RISC-V just matches what ARM/AARCH64 did for alignment considerations and
Palmer Dabbelt extended is_mapping_symbol() to accept these symbols for
RISC-V. We already had support for this for all architectures but it also
checked for the second character, the RISC-V check Dabbelt added was just
for the "$". After a bit of testing and fallout on linux-next and based on
feedback from Masahiro Yamada it was decided to simplify the check and treat
the first char "$" as unique for all architectures, and so we no make
is_mapping_symbol() for all archs if the symbol starts with "$".
The most relevant commit for this for RISC-V on binutils was:
https://sourceware.org/pipermail/binutils/2021-July/117350.html
* A late fix by Andrea Righi (today) to make module zstd decompression use
vmalloc() instead of kmalloc() to account for large compressed modules. I
suspect we'll see similar things for other decompression algorithms soon.
* samples/hw_breakpoint minor fixes by Rong Tao, Arnd Bergmann and Chen Jiahao

First of all, Unisoc's IC provides cmd delay and read delay to ensure
that the host can get the correct data. However, according to SD Spec,
there is no need to do tuning in high speed mode, but with the
development of chip processes, it is more and more difficult to find
a suitable delay to cover all the chips. Therefore, we need SD high
speed mode online tuning.
In addition, we added mmc_sd_switch() and mmc_send_status() to the
header file to allow it to be usable by the driver.

To support the need for host specific tuning for SD high-speed mode, let's
add two new optional callbacks, ->prepare|execute_sd_hs_tuning() and let's
call them when switching into the SD high-speed mode.
Note that, during the tuning process it's also needed for host drivers to
send commands to the SD card to verify that the tuning process succeeds.
Therefore, let's also share the corresponding functions from the core to
allow this.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

most of the time and there is an effort to make the callback return
void. To prepare this rework the function not to exit early.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

To conclude the ux500 busy timeout fixes, this improves the debug and

We see a lot of lost IRQs and the timeout always occur while waiting for
the end IRQ, and then the busy status is *low* meaning the busy indication
is already de-asserted.
So busy signalling is missed in various ways for various reasons,
sometimes it appears that IRQs are simply lost.
One hypothesis is that this happens because the events happen so fast
that they are transient, and since the MMCI state machine in effect is
handling an edge trigger (rising or falling signal on DAT0) the
internal logic will miss the event, because the state machine in the
hardware is sampling the line, and will at times detect only the first
event but miss the second, fireing only one IRQ.
We print the second timeout error with dev_err() since it is pretty
serious, the other events are so common and simple to handle that we
can keep them at dev_dbg() level.

When mmc allocation succeeds, the error paths are not freeing mmc.
Fix the above issue by changing mmc_alloc_host() to devm_mmc_alloc_host()
to simplify the error handling. Remove label 'probe_free_host' as devm_*
api takes care of freeing, also remove mmc_free_host() from remove
function as devm_* takes care of freeing.

mmc_add_host() may return error, if we ignore its return value,
1. the memory allocated in mmc_alloc_host() will be leaked
2. null-ptr-deref will happen when calling mmc_remove_host()
in remove function spmmc_drv_remove() because deleting not
added device.
Fix this by checking the return value of mmc_add_host(). Moreover,
I fixed the error handling path of spmmc_drv_probe() to clean up.

For a completed request, after the mmc_blk_mq_complete_rq(mq, req)
function is executed, the bitmap_tags corresponding to the
request will be cleared, that is, the request will be regarded as
idle. If the request is acquired by a different type of process at
this time, the issue_type of the request may change. It further
caused the value of mq->in_flight[issue_type] to be abnormal,
and a large number of requests could not be sent.

au1xmmc is split somewhat awkwardly into the main mmc subsystem driver,
and callbacks in platform_data that sit under arch/mips/ and are
always built in. The latter than call mmc_detect_change through
symbol_get. Remove the use of symbol_get by requiring the driver
to be built in. In the future the interrupt handlers for card
insert/eject detection should probably be moved into the main driver,
and which point it can be built modular again.

The ux500 variant doesn't have a HW based timeout to use for busy-end IRQs.
To avoid hanging and waiting for the card to stop signaling busy, let's
schedule a delayed work, according to the corresponding cmd->busy_timeout
for the command. If the work gets to run, let's kick the IRQ handler to
complete the currently running request/command.

In stm32 sdmmc variant revision v3.0, a block gap hardware flow control
should be used with bus speed modes SDR104 and HS200.
It is enabled by writing a non-null value to the new added register
MMCI_STM32_FIFOTHRR.
The threshold will be 2^(N-1) bytes, so we can use the ffs() function to
compute the value N to be written to the register. The threshold used
should be the data block size, but must not be bigger than the FIFO size.

This makes the ux500 ->busy_complete() callback re-read
the status register 10 times while waiting for the busy
signal to assert in the status register.
If this does not happen, we bail out regarding the
command completed already, i.e. before we managed to
start to check the busy status.
There is a comment in the code about this, let's just
implement it to be certain that we can catch this glitch
if it happens.

This refactors the ->busy_complete() callback currently
only used by Ux500 and STM32 to handle busy detection on
hardware where one and the same IRQ is fired whether we get
a start or an end signal on busy detect.
The code is currently using the cached status from the
command IRQ in ->busy_status as a state to select what to
do next: if this state is non-zero we are waiting for
IRQs and if it is zero we treat the state as the starting
point for a busy detect wait cycle.
Make this explicit by creating a state machine where the
->busy_complete callback moves between three states.
The Ux500 busy detect code currently assumes this order:
we enable the busy detect IRQ, get a busy start IRQ, then a
busy end IRQ, and then we clear and mask this IRQ and
proceed.
We insert debug prints for unexpected states.
This works as before on most cards, however on a
problematic card that is not working with busy detect, and
which I have been debugging, the following happens a lot:
[ 3.380554] mmci-pl18x 80005000.mmc: no busy signalling in time
[ 3.387420] mmci-pl18x 80005000.mmc: no busy signalling in time
[ 3.394561] mmci-pl18x 80005000.mmc: lost busy status
when waiting for busy start IRQ
This probably means that the busy detect start IRQ has
already occurred when we start executing the
->busy_complete() callbacks, and the busy detect end IRQ
is counted as the start IRQ, and this is what is causing
the card to not be detected properly.

The busy detect callback for Ux500 checks for an error
in the status in the first if() clause. The only practical
reason is that if an error occurs, the if()-clause is not
executed, and the code falls through to the last
if()-clause if (host->busy_status) which will clear and
disable the irq. Make this explicit instead: it is easier
to read.

If we are starting a command which can generate a busy
response, then clear the variable host->busy_status
if the variant is using a ->busy_complete callback.
We are lucky that the member is zero by default and
hopefully always gets cleared in the ->busy_complete
callback even on errors, but it's just fragile so
make sure it is always initialized to zero.

When using dm-verity with a data partition on an emmc device, dm-verity
races with the initialization of the (e)MMC/SD cards. This is because the
card detection procedure is being managed from a workqueue, rather than
synchronously from the mmc host's ->probe() routine.
To allow the card detect to be synchronous, let's simply skip using the
workqueue at the first initialization attempt from mmc_start_host().

Looking closely it's obvious that only the 32-bit part of the address
(0xfffff200) arrives at the SMMU, the higher 16-bit (0xffff...) get
lost somewhere. This might not be a limitation of the SDHCI itself but
perhaps the bus/interconnect it is connected to, or even the connection
to the SMMU.
Work around this by setting SDHCI_QUIRK2_BROKEN_64_BIT_DMA to avoid
using 64-bit addresses.

Now that there is a new dedicated ICE driver, drop the sdhci-msm ICE
implementation and use the new ICE api provided by the Qualcomm soc
driver ice. The platforms that already have ICE support will use the
API as library since there will not be a devicetree node, but instead
they have reg range. In this case, the of_qcom_ice_get will return an
ICE instance created for the consumer's device. But if there are
platforms that do not have ice reg in the consumer devicetree node
and instead provide a dedicated ICE devicetree node, theof_qcom_ice_get
will look up the device based on qcom,ice property and will get the ICE
instance registered by the probe function of the ice driver.
The ICE clock is now handle by the new driver. This is done by enabling
it on the creation of the ICE instance and then enabling/disabling it on
SDCC runtime resume/suspend.

Add support SD Express card for GL9767. The workflow of the
SD Express card in GL9767 is as below.
1. GL9767 operates in SD mode and set MMC_CAP2_SD_EXP flag.
2. If card is inserted, Host send CMD8 to ask the capabilities
of the card.
3. If the card has PCIe capability, then init_sd_express()
will be invoked.
4. If the card has been put in write protect state then the
SD features supported by SD mode but not supported by
PCIe mode, therefore GL9767 switch to SD mode.
5. If the card has not been put in write protect state then
GL9767 switch from SD mode to PCIe/NVMe mode and mmc driver
handover control to NVMe driver.
6. If card is removed, GL9767 will return to SD mode.

CQHCI_SSC1 indicates to CQE the polling period to use when using periodic
SEND_QUEUE_STATUS(CMD13) polling.
Since MSDC CQE uses msdc_hclk as ITCFVAL, so driver should use hclk
frequency to get the actual time.
The default value 0x1000 that corresponds to 150us for MediaTek SoCs, let's
decrease it to 0x40 that corresponds to 2.35us, which can improve the

Bayhub SD host has hardware limitation:
1.The upper 32bit address is inhibited to be written at SD Host Register
[03E][13]=0 (32bits addressing) mode, is admitted to be written only at
SD Host Register [03E][13]=1 (64bits addressing) mode.
2.Because of above item#1, need to configure SD Host Register [03E][13] to
1(64bits addressing mode) before set 64bit ADMA system address's higher
32bits SD Host Register [05F~05C] if 64 bits addressing mode is used.
The hardware limitation is reasonable for below reasons:
1.Normal flow should set DMA working mode first, then do
DMA-transfer-related configuration, such as system address.
2.The hardware limitation may avoid the software to configure wrong higher
32bit address at 32bits addressing mode although it is redundant.
The change that set 32bits/64bits addressing mode before set ADMA address,
has no side-effect to other host IPs for below reason:
The setting order is reasonable and standard: DMA Mode setting first and
then DMA address setting. It meets all DMA setting sequence.

Convert the drivers that use this function as .remove() callback to
.remove_new() which has the right prototype. This helps getting rid of
the platform_driver's remove callback that returns an int (which is
error prone). The other users didn't check the return value anyhow.

A recent change to the OMAP driver making it use a dynamic GPIO
base created problems with some old OMAP1 board files, among
them Nokia 770, SX1 and also the OMAP2 Nokia n8x0.
Fix up all instances of GPIOs being used for the MMC driver
by pushing the handling of power, slot selection and MMC
"cover" into the driver as optional GPIOs.
This is maybe not the most perfect solution as the MMC
framework have some central handlers for some of the
stuff, but it at least makes the situtation better and
solves the immediate issue.

Requests to the mmc layer usually come through a block device IO.
The exceptions are the ioctl interface, RPMB chardev ioctl
and debugfs, which issue their own blk_mq requests through
blk_execute_rq and do not query the BLK_STS error but the
mmcblk-internal drv_op_result. This patch ensures that drv_op_result
defaults to an error and has to be overwritten by the operation
to be considered successful.
The behavior leads to a bug where the request never propagates
the error, e.g. by directly erroring out at mmc_blk_mq_issue_rq if
mmc_blk_part_switch fails. The ioctl caller of the rpmb chardev then
can never see an error (BLK_STS_IOERR, but drv_op_result is unchanged)
and thus may assume that their call executed successfully when it did not.
While always checking the blk_execute_rq return value would be
advised, let's eliminate the error by always setting
drv_op_result as -EIO to be overwritten on success (or other error)

If spec_reg is equal to 'SDHCI_PRESENT_STATE', esdhc_readl_fixup()
fixes up register value and returns it immediately. As a result, the

Currently .get_max_clock returns the current clock rate for cclk_emmc
on rk35xx, thus max clock gets set to whatever bootloader set it to.
In case of u-boot, it is intentionally reset to 50 MHz if it boots
from eMMC, see mmc_deinit() in u-boot sources. As a result, HS200 and
HS400 modes are never selected by Linux, because dwcmshc_rk35xx_postinit
clears appropriate caps if host->mmc->f_max is < 52MHz
cclk_emmc is not a fixed clock on rk35xx, so using
sdhci_pltfm_clk_get_max_clock is not appropriate here.
Implement rk35xx_get_max_clock that returns actual max clock for cclk_emmc.

For Xilinx platforms which has DLL module, dll clock must be
ungated/enabled when SD controller operates at higher frequencies like 50
MHz, 100 MHz and 200 MHz. This will be done by explicitly requesting gate
clock from the driver.

As usual, there are lots of minor driver changes across SoC platforms
from NXP, Amlogic, AMD Zynq, Mediatek, Qualcomm, Apple and Samsung.
These usually add support for additional chip variations in existing
drivers, but also add features or bugfixes.
The SCMI firmware subsystem gains a unified raw userspace interface
through debugfs, which can be used for validation purposes.
Newly added drivers include:
- New power management drivers for StarFive JH7110, Allwinner D1 and
Renesas RZ/V2M
- A driver for Qualcomm battery and power supply status
- A SoC device driver for identifying Nuvoton WPCM450 chips
- A regulator coupler driver for Mediatek MT81xxv

Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work falls
into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be moved
into read-only memory (i.e. const) The recent work with Rust has
pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only making
things safer overall. This is the contuation of that work (started
last release with kobject changes) in moving struct bus_type to be
constant. We didn't quite make it for this release, but the
remaining patches will be finished up for the release after this
one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems.

This is a follow-up to the deprecation of most of the old-style board
files that was merged in linux-6.0, removing them for good.
This branch is almost exclusively dead code removal based on those
annotations. Some device driver removals went through separate subsystem
trees, but the majority is in the same branch, in order to better handle
dependencies between the patches and avoid breaking bisection.
Unfortunately that leads to merge conflicts against other changes in the
subsystem trees, but they should all be trivial to resolve by removing
the files.

Let's align to the common busy polling behaviour for mmc ioctls, by
updating the below two corresponding parts, that comes into play when using
an R1B response for a command.
*) A command with an R1B response should be prepared by calling
mmc_prepare_busy_cmd(), which make us respects the host's busy timeout
constraints.
**) When an R1B response is being used and the host also supports HW busy
detection, we should skip to poll for busy completion.

If sdio_add_func() or sdio_init_func() fails, sdio_remove_func() can
not release the resources, because the sdio function is not presented
in these two cases, it won't call of_node_put() or put_device().
To fix these leaks, make sdio_func_present() only control whether
device_del() needs to be called or not, then always call of_node_put()
and put_device().
In error case in sdio_init_func(), the reference of 'card->dev' is
not get, to avoid redundant put in sdio_free_func_cis(), move the
get_device() to sdio_alloc_func() and put_device() to sdio_release_func(),
it can keep the get/put function be balanced.
Without this patch, while doing fault inject test, it can get the
following leak reports, after this fix, the leak is gone.

If we enable the MMC/SD block layer, use Kconfig to imply the BFQ
I/O scheduler.
As all MMC/SD devices are single-queue, this is the scheduler that
users want so let's be helpful and make sure it gets
default-selected into a manual kernel configuration. It will still
need to be enabled at runtime (usually with udev scripts).

This commit fixes a race between completion of stop command and start of a
new command.
Previously the command ready interrupt was enabled before stop command
was written to the command register. This caused the command ready
interrupt to fire immediately since the CMDRDY flag is asserted constantly
while there is no command in progress.
Consequently the command state machine will immediately advance to the
next state when the tasklet function is executed again, no matter
actual completion state of the stop command.
Thus a new command can then be dispatched immediately, interrupting and
corrupting the stop command on the CMD line.
Fix that by dropping the command ready interrupt enable before calling
atmci_send_stop_cmd. atmci_send_stop_cmd does already enable the
command ready interrupt, no further writes to ATMCI_IER are necessary.

Add ability to have an optional core clock just like the pxav3 driver.
The PXA168 needs this because its SDHC controllers have separate core
and io clocks that both need to be enabled. This also correctly matches
the documented devicetree bindings for this driver.

USDHC IP has one limitation: the tuning circuit can't handle the async
sdio device interrupt correctly. When sdio device use 4 data lines,
async sdio interrupt will use the shared DAT[1], if enable auto tuning
circuit to check these 4 data lines, include the DAT[1], this circuit
will detect this interrupt, take this as data on DAT[1], and adjust the
delay cell wrongly, finally will cause the DATA/CMD CRC error.
So for SDIO device, only enable DAT[0] and CMD line for auto tuning.
To distinguish the card type during card init, involve init_card().

Merge tag 'random-6.2-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
Pull random number generator updates from Jason Donenfeld:
- Replace prandom_u32_max() and various open-coded variants of it,
there is now a new family of functions that uses fast rejection
sampling to choose properly uniformly random numbers within an
interval:
get_random_u32_below(ceil) - [0, ceil)
get_random_u32_above(floor) - (floor, U32_MAX]
get_random_u32_inclusive(floor, ceil) - [floor, ceil]
Coccinelle was used to convert all current users of
prandom_u32_max(), as well as many open-coded patterns, resulting in
improvements throughout the tree.
I'll have a "late" 6.1-rc1 pull for you that removes the now unused
prandom_u32_max() function, just in case any other trees add a new
use case of it that needs to converted. According to linux-next,
there may be two trivial cases of prandom_u32_max() reintroductions
that are fixable with a 's/.../.../'. So I'll have for you a final
conversion patch doing that alongside the removal patch during the
second week.
This is a treewide change that touches many files throughout.
- More consistent use of get_random_canary().
- Updates to comments, documentation, tests, headers, and
simplification in configuration.
- The arch_get_random*_early() abstraction was only used by arm64 and
wasn't entirely useful, so this has been replaced by code that works
in all relevant contexts.
- The kernel will use and manage random seeds in non-volatile EFI
variables, refreshing a variable with a fresh seed when the RNG is
initialized. The RNG GUID namespace is then hidden from efivarfs to
prevent accidental leakage.
These changes are split into random.c infrastructure code used in the
EFI subsystem, in this pull request, and related support inside of
EFISTUB, in Ard's EFI tree. These are co-dependent for full
functionality, but the order of merging doesn't matter.
- Part of the infrastructure added for the EFI support is also used for
an improvement to the way vsprintf initializes its siphash key,
replacing an sleep loop wart.
- The hardware RNG framework now always calls its correct random.c
input function, add_hwgenerator_randomness(), rather than sometimes
going through helpers better suited for other cases.
- The add_latent_entropy() function has long been called from the fork
handler, but is a no-op when the latent entropy gcc plugin isn't
used, which is fine for the purposes of latent entropy.
But it was missing out on the cycle counter that was also being mixed
in beside the latent entropy variable. So now, if the latent entropy
gcc plugin isn't enabled, add_latent_entropy() will expand to a call
to add_device_randomness(NULL, 0), which adds a cycle counter,
without the absent latent entropy variable.
- The RNG is now reseeded from a delayed worker, rather than on demand
when used. Always running from a worker allows it to make use of the
CPU RNG on platforms like S390x, whose instructions are too slow to
do so from interrupts. It also has the effect of adding in new inputs
more frequently with more regularity, amounting to a long term
transcript of random values. Plus, it helps a bit with the upcoming
vDSO implementation (which isn't yet ready for 6.2).
- The jitter entropy algorithm now tries to execute on many different
CPUs, round-robining, in hopes of hitting even more memory latencies
and other unpredictable effects. It also will mix in a cycle counter
when the entropy timer fires, in addition to being mixed in from the
main loop, to account more explicitly for fluctuations in that timer
firing. And the state it touches is now kept within the same cache
line, so that it's assured that the different execution contexts will
cause latencies.

In case of error condition to avoid system crash Tegra SDMMC controller
requires CMD and DAT resets issued together. SDHCI controller FSM goes
into bad state due to rapid SD card hot-plug event. Issuing reset on the
CMD FSM before DATA FSM results in kernel panic, hence add support to
issue CMD and DAT resets together.
This is applicable to Tegra186 and later chips.

Current next_tag selection will cause a large delay in some requests and
destroy the scheduling results of the block scheduling layer. Because the
issued mrq tags cannot ensure that each time is sequential, especially when
the IO load is heavy. In the fio performance test, we found that 4k random
read data was sent to mmc_hsq to start calling request_atomic It takes
nearly 200ms to process the request, while mmc_hsq has processed thousands
of other requests. So we use fifo here to ensure the first in, first out
feature of the request and avoid adding additional delay to the request.

The workaround of pretending R1B non-data transfers are data transfers in
order for the busy timeout to be respected by the host controller driver is
removed. It wasn't useful in a long time.
Initially the workaround ensured that R1B commands did not time out by
setting the data timeout to be the command timeout in commit cb87ea28ed
("mmc: core: Add mmc CMD+ACMD passthrough ioctl"). This was moved inside an
if-clause with idata->buf_bytes being set in commit 4d6144de8b ("mmc:
core: check for zero length ioctl data"). Since the workaround is now
inside the idata->buf_bytes clause and intended to fix R1B non-data
transfers, that do not have buf_bytes set, we can remove the workaround
altogether. This was dead code, since data transfers doesn't use R1B
commands.

transfers as done implying that DMA end interrupts have occurred by then
anyhow. On some SoCs under some conditions, this turned out to be not
enough. So, we enable DMA interrupts as well and make sure that both
events, DMA irq and access_end irq, have happened before finishing the
DMA transfer.

mmc_add_host() may return error, if we ignore its return value,
it will lead two issues:
1. The memory that allocated in mmc_alloc_host() is leaked.
2. In the remove() path, mmc_remove_host() will be called to
delete device, but it's not added yet, it will lead a kernel
crash because of null-ptr-deref in device_del().
So fix this by checking the return value and goto error path which
will call mmc_free_host().

This driver often takes on the order of 10ms to start, but in some cases
as much as 190ms. It shouldn't have many cross-device dependencies to
race with, nor racy access to shared state with other drivers, so this
should be a relatively low risk change. We've done similarly with a
variety of other MMC host drivers already.
This driver was pinpointed as part of a survey of top slowest initcalls
(i.e., are built in, and probing synchronously) on a lab of ChromeOS
systems.

For standard tuning method on usdhc, the previous tuning result can
impact current tuning result, let current tuning can't set the correct
delay cell. And from the logic, this is also reasonable for manual
tuning method. So reset the tuning logic before execute tuning.
To avoid compile issue, this patch also move the esdhc_reset_tuning()
upper.
Find this issue when support SDIO WiFi in band wakeup feature. After
system resume back, will do re-tuning, but then meet data CRC error.
Do not meet this issue on SD/eMMC, because we already call
esdhc_reset_tuning() when config the legency ios, and SD/eMMC need
to re-init when system resume back, but SDIO device don't do re-init
if it has MMC_PM_KEEP_POWER pm_flags.

commit 3e4d3af501 ("mm: stack based kmap_atomic()").
Remove local_irq_{save,restore}() around sg_miter_{next,stop}().

A long time ago the kmap_atomic API required a slot to be provided which
risked the possibility that other code might use the same slot at the
same time. Disabling interrupts prevented the possibility of an interrupt
handler doing that. However, that went away with
commit 3e4d3af501 ("mm: stack based kmap_atomic()").
When the second argument to kmap_atomic was removed by commit 482fce997e
("mmc: remove the second argument of k[un]map_atomic()"),
local_irq_{save,restore}() should have been removed also.
Remove it now.

After switching the voltage, no reset data and command will cause
CMD2 timeout.

Commit 20b92a30b5 ("mmc: sdhci: update signal voltage switch code")
removed voltage switch delays from sdhci because mmc core had been
enhanced to support them. However that assumed that sdhci_set_ios()
did a single clock change, which it did not, and so the delays in mmc
core, which should have come after the first clock change, were not
effective.
Fix by avoiding re-configuring UHS and preset settings when the clock
is turning on and the settings have not changed. That then also avoids
the associated clock changes, so that then sdhci_set_ios() does a single
clock change when voltage switching, and the mmc core delays become
effective.
To do that has meant keeping track of driver strength (host->drv_type),
and cases of reinitialization (host->reinit_uhs).
Note also, the 'turning_on_clk' restriction should not be necessary
but is done to minimize the impact of the change on stable kernels.
