bcd241230f remoteproc: core: Release rproc->clean_table after rproc_attach() fails
When rproc->state = RPROC_DETACHED is attached to remote processor
through rproc_attach(), if rproc_handle_resources() returns failure,
then the clean table should be released, otherwise the following
memory leak will occur.

7692c9fbed remoteproc: core: Cleanup acquired resources when rproc_handle_resources() fails in rproc_attach()
When rproc->state = RPROC_DETACHED and rproc_attach() is used
to attach to the remote processor, if rproc_handle_resources()
returns a failure, the resources allocated by imx_rproc_prepare()
should be released, otherwise the following memory leak will occur.

Since almost the same thing is done in imx_rproc_prepare() and
rproc_resource_cleanup(), Function rproc_resource_cleanup() is able
to deal with empty lists so it is better to fix the "goto" statements
in rproc_attach(). replace the "unprepare_device" goto statement with
"clean_up_resources" and get rid of the "unprepare_device" label.

ab7bca5acd remoteproc: imx_dsp_rproc: Add support for DSP-specific features
Some DSP firmware requires a FW_READY signal before proceeding, while
others do not.
Therefore, add support to handle i.MX DSP-specific features.

Implement handle_rsc callback to handle resource table parsing and to
process DSP-specific resource, to determine if waiting is needed.

Update imx_dsp_rproc_start() to handle this condition accordingly.

efdde3d73a remoteproc: core: Clear table_sz when rproc_shutdown
There is case as below could trigger kernel dump:
Use U-Boot to start remote processor(rproc) with resource table
published to a fixed address by rproc. After Kernel boots up,
stop the rproc, load a new firmware which doesn't have resource table
,and start rproc.

When starting rproc with a firmware not have resource table,
`memcpy(loaded_table, rproc->cached_table, rproc->table_sz)` will
trigger dump, because rproc->cache_table is set to NULL during the last
stop operation, but rproc->table_sz is still valid.

This issue is found on i.MX8MP and i.MX9.

0184b4fdba imx_dsp_rproc: Use reset controller API to control the DSP
DSP on i.MX8MP doesn't have a direct reset line so according to hardware
design team in order to handle assert/deassert/reset functionality we
need to use a combination of control bits from two modules. Audio block
control module for Run/Stall control of the DSP and DAP module in order
to do software reset.

In a first step, for i.MX8MP we are switching on using the reset
controller API to handle the DSP Run/Stall bits i.MX8MP. This comes with
the advantage of offering a better probe ordering and a more natural way
of abstracting the Audio block control bits.

dbb9c37255 remoteproc: mtk_scp: Only populate devices for SCP cores
When multi-core SCP support was added, the driver was made to populate
platform devices for all the sub-nodes. This ended up adding platform
devices for the rpmsg sub-nodes as well, which never actually get used,
since rpmsg devices are registered through the rpmsg interface.

Limit of_platform_populate() to just populating the SCP cores with a
compatible string match list.

7378aeb664 remoteproc: core: Fix ida_free call while not allocated
In the rproc_alloc() function, on error, put_device(&rproc->dev) is
called, leading to the call of the rproc_type_release() function.
An error can occurs before ida_alloc is called.

In such case in rproc_type_release(), the condition (rproc->index >= 0) is
true as rproc->index has been  initialized to 0.
ida_free() is called reporting a warning:

Currently, the rproc "atomic_t power" variable is incremented during:
a. WPSS rproc auto boot.
b. AHB power on for ath11k.

During AHB power off (rmmod ath11k_ahb.ko), rproc_shutdown fails
to unload the WPSS firmware because the rproc->power value is '2',
causing the atomic_dec_and_test(&rproc->power) condition to fail.

Consequently, during AHB power on (insmod ath11k_ahb.ko),
QMI_WLANFW_HOST_CAP_REQ_V01 fails due to the host and firmware QMI
states being out of sync.

After commit 0edb555a65 ("platform: Make platform_driver::remove()

Convert all platform drivers below drivers/remoteproc to use .remove(),
with the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

9c12b96ee2 mailbox, remoteproc: k3-m4+: fix compile testing
The k3-m4 remoteproc driver was merged with incorrect dependencies.
Despite multiple people trying to fix this, the version 6.12-rc2
remains broken and causes a build failure with CONFIG_TI_SCI_PROTOCOL=m
when the driver is built-in.

arm-linux-gnueabi-ld: drivers/remoteproc/ti_k3_m4_remoteproc.o: in function `k3_m4_rproc_probe':
ti_k3_m4_remoteproc.c:(.text.k3_m4_rproc_probe+0x76): undefined reference to `devm_ti_sci_get_by_phandle'

Fix the dependency again to make it work in all configurations.
The 'select OMAP2PLUS_MBOX' no longer matches what the other drivers
dependencies. The link failure can be avoided with a simple 'depends
do, so turn that into the same 'depends' to ensure we get no circular
on TI_SCI_PROTOCOL', but the extra COMPILE_TEST alternative is what
we use elsehwere. On the other hand, building for OMAP2PLUS makes
no sense since the hardware only exists on K3.

Using 'select' to force-enable another subsystem is generally
a mistake and causes problems such as this one, so change the
three drivers that link against this driver to use 'depends on'
instead, and ensure the driver itself can be compile tested
regardless of the platform.

When compile-testing without CONFIG_TI_SCI_PROTOCOL=m, there
is a chance for a link failure, so add a careful dependency
on that.

The TI_K3_M4_REMOTEPROC Kconfig entry selects OMAP2PLUS_MBOX, but that

This causes a Kconfig time warning:

    Selected by [m]:

because you can't select something that is unavailable.

Make the dependencies for TI_K3_M4_REMOTEPROC match those of the
OMAP2PLUS_MBOX driver that it needs.

ff555fc553 remoteproc: imx_rproc: Add support for poweroff and reboot
On some NXP platforms (e.g i.MX7ULP) the poweroff and reboot operations
are done via a separate remote core.

Typically Linux needs to send a message to the remote core and requests
for poweroff or reboot.

By default the communication between Linux core and the remote core is
is done via a blocking mailbox mechanism but Linux doesn't allow blocking
operations in the system off (reboot, power off) handlers.

So, we need to make sure the mailbox message send operations do not block
for this specific operations. Fortunately, Linux allows us to register
handlers that are called in preparation of the system off operations.

Thus, before carrying the power off or reboot preparations, just destroy
the existing mailboxes and create them as non-blocking.

Note that power off and restart are totally different operations and are
not complementary.

We introduce a new flag in the imx remoteproc per device data which tells
us when a device needs this special setup. For now, only imx7ulp needs it.

ebcf9008a8 remoteproc: k3-m4: Add a remoteproc driver for M4F subsystem
The AM62x and AM64x SoCs of the TI K3 family has a Cortex M4F core in
the MCU domain. This core is typically used for safety applications in a
stand alone mode. However, some application (non safety related) may
want to use the M4F core as a generic remote processor with IPC to the
host processor. The M4F core has internal IRAM and DRAM memories and are
exposed to the system bus for code and data loading.

A remote processor driver is added to support this subsystem, including
being able to load and boot the M4F core. Loading includes to M4F
internal memories and predefined external code/data memories. The
carve outs for external contiguous memory is defined in the M4F device
node and should match with the external memory declarations in the M4F
image binary. The M4F subsystem has two resets. One reset is for the
entire subsystem i.e including the internal memories and the other, a
local reset is only for the M4F processing core. When loading the image,
the driver first releases the subsystem reset, loads the firmware image
and then releases the local reset to let the M4F processing core run.

ba70bbfd28 remoteproc: Use of_property_present()
Use of_property_present() to test for property presence rather than
of_(find|get)_property(). This is part of a larger effort to remove
callers of of_find_property() and similar functions. of_find_property()
leaks the DT struct property and data pointers which is a problem for
dynamically allocated nodes which may be freed.

If there is a resource table device tree node, use the address as

.resource_table section loaded) inside the Cortex-M elf file.

And there is an update in NXP SDK that Resource Domain Control(RDC)
enabled to protect TCM, linux not able to write the TCM space when
updating resource table status and cause kernel dump. So use the address
from device tree could avoid kernel dump.

Note: NXP M4 SDK not check resource table update, so it does not matter
use whether resource table address specified in elf file or in device
tree. But to reflect the fact that if people specific resource table
address in device tree, it means people are aware and going to use it,

a8631f6d63 remoteproc: k3-r5: Fix IPC-only mode detection
ret variable was used to test reset status, get from
reset_control_status() call. But this variable was overwritten by
ti_sci_proc_get_status() a few lines bellow.
And as ti_sci_proc_get_status() returns 0 or a negative value (in this
latter case, followed by a return), the expression !ret was always true,

Clearly, this was not what was intended:
In the comment above it's said that "requires both local and module
resets to be deasserted"; if reset_control_status() returns 0 it means
that the reset line is deasserted.
So, it's pretty clear that the return value of reset_control_status()
was intended to be used instead of ti_sci_proc_get_status() return
value.

This could lead in an incorrect IPC-only mode detection if reset line is
asserted (so reset_control_status() return > 0) and c_state != 0 and
halted == 0.
In this case, the old code would have detected an IPC-only mode instead
of a mismatched mode.

Add a check so that the remapping is only attempted if the memory region
exists. This also allows to simplify the logic handling failure to
remap, since a failure then is always a failure.
