Rather busy cycle. We have a total 99 non-merge commits going into v5.8
merge window. The majority of the changes are in dwc3 this around (31.7%
of all changes). It's composed mostly Thinh's recent updates to get dwc3
to behave correctly with stream transfers. We have also have Roger's for
Keystone platforms and Neil's updates for the meson glue layer.
Apart from those, we have the usual set of non-critical fixes, new
device IDs, spelling fixes all over the place.

This patch adds new config_ep_by_speed_and_alt function which
extends the config_ep_by_speed about alt parameter.
This additional parameter allows to find proper usb_ss_ep_comp_descriptor.
Problem has appeared during testing f_tcm (BOT/UAS) driver function.
f_tcm function for SS use array of headers for both BOT/UAS alternate
setting:
static struct usb_descriptor_header *uasp_ss_function_desc[] = {
(struct usb_descriptor_header *) &bot_intf_desc,
(struct usb_descriptor_header *) &uasp_ss_bi_desc,
(struct usb_descriptor_header *) &bot_bi_ep_comp_desc,
(struct usb_descriptor_header *) &uasp_ss_bo_desc,
(struct usb_descriptor_header *) &bot_bo_ep_comp_desc,
(struct usb_descriptor_header *) &uasp_intf_desc,
(struct usb_descriptor_header *) &uasp_ss_bi_desc,
(struct usb_descriptor_header *) &uasp_bi_ep_comp_desc,
(struct usb_descriptor_header *) &uasp_bi_pipe_desc,
(struct usb_descriptor_header *) &uasp_ss_bo_desc,
(struct usb_descriptor_header *) &uasp_bo_ep_comp_desc,
(struct usb_descriptor_header *) &uasp_bo_pipe_desc,
(struct usb_descriptor_header *) &uasp_ss_status_desc,
(struct usb_descriptor_header *) &uasp_status_in_ep_comp_desc,
(struct usb_descriptor_header *) &uasp_status_pipe_desc,
(struct usb_descriptor_header *) &uasp_ss_cmd_desc,
(struct usb_descriptor_header *) &uasp_cmd_comp_desc,
(struct usb_descriptor_header *) &uasp_cmd_pipe_desc,
NULL,
};
The first 5 descriptors are associated with BOT alternate setting,
and others are associated with UAS.
During handling UAS alternate setting f_tcm driver invokes
config_ep_by_speed and this function sets incorrect companion endpoint
descriptor in usb_ep object.
Instead setting ep->comp_desc to uasp_bi_ep_comp_desc function in this
case set ep->comp_desc to uasp_ss_bi_desc.
This is due to the fact that it searches endpoint based on endpoint
address:
for_each_ep_desc(speed_desc, d_spd) {
chosen_desc = (struct usb_endpoint_descriptor *)*d_spd;
if (chosen_desc->bEndpoitAddress == _ep->address)
goto ep_found;
}
And in result it uses the descriptor from BOT alternate setting
instead UAS.
Finally, it causes that controller driver during enabling endpoints
detect that just enabled endpoint for bot.

The threaded interrupt handler may still be called after the
usb_gadget_disconnect is called, it causes the structures used
at interrupt handler was freed before it uses, eg the
usb_request. This issue usually occurs we remove the udc function
during the transfer. Below is the example when doing stress
test for android switch function, the EP0's request is freed
by .unbind (configfs_composite_unbind -> composite_dev_cleanup),
but the threaded handler accesses this request during handling
setup packet request.
In fact, there is no protection between unbind the udc
and udc interrupt handling, so we have to avoid the interrupt
handler is occurred or scheduled during the .unbind flow.

To take advantage of DWC3 internal TRB prefetch and cache for
performance, inform the controller the last request with stream_id
before switching to a different stream transfer. This allows the
controller to maintain its transfer burst within the stream ID.
Introduce the usb-request is_last field to help inform the DWC3
controller of this.

of other changes are found in ASoC scene.
Here are some highlights:
* ALSA core:
- More helper macros for sparse warning fixes (e.g. bitwise types)
- Slight optimization of PCM OSS locks
- Make common handling for PCM / compress buffers (for SOF)
* ASoC:
- Lots of code refactoring and modernization for (still ongoing)
componentization works
- Conversion of SND_SOC_ALL_CODECS to use imply
- Continued refactoring and fixing of the Intel SOF/SST support,
including the initial (but still incomplete) SoundWire support
- SoundWire and more advanced clocking support for Realtek RT5682
- Support for amlogic GX, Meson 8, Meson 8B and T9015 DAC, Broadcom
DSL/PON, Ingenic JZ4760 and JZ4770, Realtek RL6231, and TI TAS2563
and TLV320ADCX140
* HD-audio:
- Optimizations in HDMI jack handling
- A few new quirks and fixups for Realtek codecs
* USB-audio:
- Delayed registration support
- New quirks for Motu, Kingston, Presonus

- Support for amlogic GX, Meson 8, Meson 8B and T9015 DAC, Broadcom
DSL/PON, Ingenic JZ4760 and JZ4770, Realtek RL6231, and TI TAS2563 and
TLV320ADCX140.
The NCM specification defines two formats of transfer blocks: with 16-bit
fields (NTB-16) and with 32-bit fields (NTB-32). Currently only NTB-16 is
implemented.
This patch adds the support of NTB-32. The motivation behind this is that
some devices such as E5785 or E5885 from the current generation of Huawei
LTE routers do not support NTB-16. The previous generations of Huawei
devices are also use NTB-32 by default.
Also this patch enables NTB-32 by default for Huawei devices.
During the 2019 ValdikSS made five attempts to contact Huawei to add the
NTB-16 support to their router firmware, but they were unsuccessful.

This adds separate header file for the Thunderbolt 3
Alternate Mode (aka. TBT). The header supplies definitions for
all the Thunderbolt specific VDOs (Vendor Defined Objects)
that are described in the USB Type-C Connector specification
v2.0, as well as definition for the Thunderbolt 3 Standard

There is also a new connector state value for the

The USB role callback functions had a parameter pointing to
the parent device (struct device) of the switch. The
assumption was that the switch parent is always the
controller. Firstly, that may not be true in every case, and
secondly, it prevents us from supporting devices that supply
multiple muxes.
Changing the first parameter of usb_role_switch_set_t and
usb_role_switch_get_t from struct device to struct
usb_role_switch.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

Since EHCI/OHCI controllers on R-Car Gen3 SoCs are possible to
be getting stuck very rarely after a full/low usb device was
disconnected. To detect/recover from such a situation, the controllers
require a special way which poll the EHCI PORTSC register and changes
the OHCI functional state.
So, this patch adds a polling timer into the ehci-platform driver,
and if the ehci driver detects the issue by the EHCI PORTSC register,
the ehci driver removes a companion device (= the OHCI controller)
to change the OHCI functional state to USB Reset once. And then,
the ehci driver adds the companion device again.

PHY driver updates also touched USB drivers, so that is coming in

- musb driver updates
- USB gadget driver updates
- PHY driver updates
- USB PHY driver updates
- lots of USB serial stuff fixed up
- USB typec updates
- USB-IP fixes

Instead of using the legacy GPIO API and keeping track on
polarity inversion semantics in the driver, switch to use
GPIO descriptors for this driver and change all consumers
in the process.
This makes it possible to retire platform data completely:
the only remaining platform data member was "wakeup" which
was intended to make the vbus interrupt wakeup capable,
but was not set by any users and thus remained unused. VBUS
was not waking any devices up. Leave a comment about it so
later developers using the platform can consider setting it
to always enabled so plugging in USB wakes up the platform.

Commit e0d795e4f3 ("usb: irda: cleanup on ir-usb module") added a USB
IrDA header with common defines, but mistakingly switched to using the
class-descriptor baud-rate bitmask values for the outbound header.
This broke link-speed handling for rates above 9600 baud, but a device
would also be able to operate at the default 9600 baud until a
link-speed request was issued (e.g. using the TCGETS ioctl).

Other than that, lots of little things. The usual gadget and xhci and

The main change this time around is a cleanup of some of the oldest
platforms based on the XScale and ARM9 CPU cores, which are between 10
and 20 years old.
The Kendin/Micrel/Microchip KS8695, Winbond/Nuvoton W90x900 and Intel
IOP33x/IOP13xx platforms are removed after we determined that nobody is
using them any more.
The TI Davinci and NXP LPC32xx platforms on the other hand are still in
active use and are converted to the ARCH_MULTIPLATFORM build, meaning
that we can compile a kernel that works on these along with most other
ARMv5 platforms. Changes toward that goal are also merged for IOP32x,
but additional work is needed to complete this. Patches for the
remaining ARMv5 platforms have started but need more work and some
testing.
Support for the new ASpeed AST2600 gets added, this is based on the
Cortex-A7 ARMv7 core, and is a newer version of the existing ARMv5 and
ARMv6 chips in the same family.
Other changes include a cleanup of the ST-Ericsson ux500 platform
and the move of the TI Davinci platform to a new clocksource driver.

[ The changes had marked INTEL_IOP_ADMA and USB_LPC32XX as being
buildable on other platforms through COMPILE_TEST, but that causes new
warnings that I most definitely do not want to see during the merge
window as that could hide other issues.
So the COMPILE_TEST option got disabled for them again - Linus ]

The split into multiple structures of the "ll" register bank is
impractical. It makes it hard to add ll_lfps_timers_2 which is
at offset 0x794, which is outside of the existing "lfps" structure
and would require us to add yet another one.
Instead, move all the "ll" registers into a single usb338x_ll_regs
structure, and add ll_lfps_timers_2 while at it. It will be used
in a subsequent patch.

The usb core is the only major place in the kernel that checks for
a non-NULL device dma_mask to see if a device is DMA capable. This
is generally a bad idea, as all major busses always set up a DMA mask,
even if the device is not DMA capable - in fact bus layers like PCI
can't even know if a device is DMA capable at enumeration time. This
leads to lots of workaround in HCD drivers, and also prevented us from
setting up a DMA mask for platform devices by default last time we
tried.
Replace this guess with an explicit HCD_DMA that is set by drivers that
appear to have DMA support.

The USB buffer allocation code is the only place in the usb core (and in
fact the whole kernel) that uses is_device_dma_capable, while the URB
mapping code uses the uses_dma flag in struct usb_bus. Switch the buffer
allocation to use the uses_dma flag used by the rest of the USB code,
and create a helper in hcd.h that checks this flag as well as the
CONFIG_HAS_DMA to simplify the caller a bit.

USB: more changes for v5.3 merge window
Turns out a few more important changes came about. We have the new
Cadence DRD Driver being added here and that's the biggest, most
important part.
Together with that we have suport for new imx7ulp phy. Support for
TigerLake Devices on dwc3. Also a couple important fixes which weren't
completed in time for the -rc cycle.

For HCs that have local memory, replace the current DMA API usage with
a genalloc generic allocator to manage the mappings for these devices.
To help users, introduce a new HCD API, usb_hcd_setup_local_mem() that
will setup up the genalloc backing up the device local memory. It will
be used in subsequent patches. This is in preparation for dropping
the existing "coherent" dma mem declaration APIs. The current
implementation was relying on a short circuit in the DMA API that in
the end, was acting as an allocator for these type of devices.

Registering real device entries (struct device) for the mode
muxes as well as for the orientation switches.
The Type-C mux code was deliberately attempting to avoid
creation of separate device entries for the orientation
switch and the mode switch (alternate modes) because they
are not physical devices. They are functions of a single
physical multiplexer/demultiplexer switch device.
Unfortunately because of the dependency we still have on the
underlying mux device driver, we had to put in hacks like
the one in the commit 3e3b81965c ("usb: typec: mux: Take
care of driver module reference counting") to make sure the
driver does not disappear from underneath us. Even with
those hacks we were still left with a potential NUll pointer
dereference scenario, so just creating the device entries,
and letting the core take care of the dependencies. No more
hacks needed.

In some places, the code prints a human-readable USB endpoint
transfer type (e.g. "bulk"). This involves a switch statement
sometimes wrapped around in ({ ... }) block leading to code
repetition.
To make this scenario easier, here introduces usb_ep_type_string()

endpoint type.
It also changes a few places switch was used to use this

Latest NVIDIA GPUs support VirtualLink device. Since USBIF
has not assigned a Standard ID (SID) for VirtualLink
so using NVIDA VID 0x955 as SVID.

Some tcpc device-drivers need to explicitly be told to watch for connection
events, otherwise the tcpc will not generate any TCPM_CC_EVENTs and devices
being plugged into the Type-C port will not be noticed.
For dual-role ports tcpm_start_drp_toggling() is used to tell the tcpc to
watch for connection events. Sofar we lack a similar callback to the tcpc
for single-role ports. With some tcpc-s such as the fusb302 this means
no TCPM_CC_EVENTs will be generated when the port is configured as a
single-role port.
This commit renames start_drp_toggling to start_toggling and since the
device-properties are parsed by the tcpm-core, adds a port_type parameter
to the start_toggling callback so that the tcpc_dev driver knows the
port-type and can act accordingly when it starts toggling.
The new start_toggling callback now always gets called if defined, instead
of only being called for DRP ports.
To avoid this causing undesirable functional changes all existing
start_drp_toggling implementations are not only renamed to start_toggling,
but also get a port_type check added and return -EOPNOTSUPP when port_type
is not DRP.

In some places, the code prints a human-readable USB endpoint
transfer type (e.g. "bulk"). This involves a switch statement
sometimes wrapped around in ({ ... }) block leading to code
repetition.
To make this scenario easier, here introduces usb_ep_type_string()
function, which returns a human-readable name of provided
endpoint type.
It also changes a few places switch was used to use this
new function.
