Previously we were filtering out only upper unsupported sampling rates.
This patch adds filtering of the lower unsupported sampling rates. As a
result there is 1:1 mapping between altsetting and supported rates.
The issue was found on a Scarlett 3rd Gen card (see linked bug), but the
same filtering is likely needed for the Scarlett 1st and 2nd Gen as well
as the older Clarett cards which lacks Valid Alternate Setting Control.
Patch was not tested on a real hardware.

The find_substream() call may return NULL, but the error path
dereferenced 'subs' unconditionally via dev_err(&subs->dev->dev, ...),
causing a NULL pointer dereference when subs is NULL.
Fix by switching to &uadev[idx].udev->dev which is always valid
in this context.

In snd_usb_get_audioformat_uac3(), the length value returned from
snd_usb_ctl_msg() is used directly for memory allocation without
validation. This length is controlled by the USB device.
The allocated buffer is cast to a uac3_cluster_header_descriptor
and its fields are accessed without verifying that the buffer
is large enough. If the device returns a smaller than expected
length, this leads to an out-of-bounds read.
Add a length check to ensure the buffer is large enough for
uac3_cluster_header_descriptor.

Most of changes are about ASoC, especially lots of AVS driver fixes.
Larger LOCs are seen in TAS571x codec drivers, but the changes are
trivial and safe. The rest are all device-specific small fixes.

Included in here are the following:
- USB offload support for audio devices. I think this takes the
record for the most number of patch series (30+) over the longest
period of time (2+ years) to get merged properly. Many props go to
Wesley Cheng for seeing this effort through, they took a major
out-of-tree hacked-up-monstrosity that was created by multiple
vendors for their specific devices, got it all merged into a
semi-coherent set of changes, and got all of the different major
subsystems to agree on how this should be implemented both with
changes to their code as well as userspace apis, AND wrangled the
hardware companies into agreeing to go forward with this, despite
making them all redo work they had already done in their private
device trees. This feature offers major power savings on embedded
devices where a USB audio stream can continue to flow while the rest
of the system is sleeping, something that devices running on battery
power really care about. There are still some more small tweaks
left to be done here, and those patches are still out for review and
arguing among the different hardware companies, but this is a major
step forward and a great example of how to do upstream development
well.
- small number of thunderbolt fixes and updates, things seem to be
slowing down here (famous last words...)
- xhci refactors and reworking to try to handle some rough corner
cases in some hardware implementations where things don't always
work properly
- typec driver updates
- USB3 power management reworking and updates
- Removal of some old and orphaned UDC gadget drivers that had not
been used in a very long time, dropping over 11 thousand lines from
the tree, always a nice thing, making up for the 12k lines added for

uaudio_transfer_buffer_setup() allocates a buffer for the subs->dev
device, and the returned address for the buffer is a CPU local virtual
address that may or may not be in the linear mapping, as well as a DMA
address token that is accessible by the USB device, and this in turn
may or may not correspond to the physical address.
The use in the driver however assumes that these addresses are the
linear map and the CPU physical address, respectively. Both are
nonportable here, but in the end only the virtual address gets
used by converting it to a physical address that gets mapped into
a second iommu.
Make this more explicit by pulling the conversion out first
and warning if it is not part of the linear map, and using the
actual physical address to map into the iommu in place of the
dma address that may already be iommu-mapped into the usb host.

While trying to understand a bug in the audio offload code, I had
to spend extra time due to unfortunate nameing of local variables
and struct members.
Change these to more conventional names that reflect the actual
usage:
- pointers to the CPU virtual addresses of a dma buffer get a
_cpu suffix to disambiguate them for MMIO virtual addresses
- MMIO virtual addresses that are mapped explicitly through
the IOMMU get a _iova suffix consistently, rather than a
mix of iova and va.
- DMA addresses (dma_addr_t) that are in a device address
space (linear or IOMMU) get a _dma suffix in place of the
_pa suffix.
- CPU physical (phys_addr_t) addresses get a _pa suffix.
There is still a mixup with dma addresses here that I address
in another patch.
No functional changes are intended here.

The USB-audio MIDI code initializes the timer, but in a rare case, the
driver might be freed without the disconnect call. This leaves the
timer in an active state while the assigned object is released via
snd_usbmidi_free(), which ends up with a kernel warning when the debug
configuration is enabled, as spotted by fuzzer.
For avoiding the problem, put timer_shutdown_sync() at
snd_usbmidi_free(), so that the timer can be killed properly.
While we're at it, replace the existing timer_delete_sync() at the
disconnect callback with timer_shutdown_sync(), too.

The MIDI substream name string is constructed from the combination of
the card shortname (which is taken from USB iProduct) and the USB
iJack. The problem is that some devices put the product name to the
iJack field, too. For example, aplaymidi -l output on the Lanchkey MK
49 are like:
% aplaymidi -l
Port Client name Port name
44:0 Launchkey MK4 49 Launchkey MK4 49 Launchkey MK4
44:1 Launchkey MK4 49 Launchkey MK4 49 Launchkey MK4
where the actual iJack name can't be seen because it's truncated due
to the doubly words.
For resolving those situations, this patch compares the iJack string
with the card shortname, and drops if both start with the same words.
Then the result becomes like:
% aplaymidi -l
Port Client name Port name
40:0 Launchkey MK4 49 Launchkey MK4 49 MIDI In
40:1 Launchkey MK4 49 Launchkey MK4 49 DAW In
A caveat is that there are some pre-defined names for certain
devices in the driver code, and this workaround shouldn't be applied
to them. Similarly, when the iJack isn't specified, we should skip
this check, too. The patch added those checks in addition to the
string comparison.

During initialisation of Focusrite USB audio interfaces, -EPROTO is
sometimes returned from usb_set_interface(), which sometimes prevents
the device from working: subsequent usb_set_interface() and
uac_clock_source_is_valid() calls fail.
This patch adds up to 5 retries in endpoint_set_interface(), with a
delay starting at 5ms and doubling each time. 5 retries was chosen to
allow for longer than expected waits for the interface to start
responding correctly; in testing, a single 5ms delay was sufficient to
fix the issue.

and PCM index the USB device is mapped to for supporting offloading. In
the USB audio offloading framework, the ASoC BE DAI link is the entity
responsible for registering to the SOC USB layer.
It is expected for the USB SND offloading driver to add the kcontrol to the
sound card associated with the USB audio device. An example output would
look like:
tinymix -D 1 get 'USB Offload Playback Route PCM#0'
-1, -1 (range -1->255)
This example signifies that there is no mapped ASoC path available for the
USB SND device.
tinymix -D 1 get 'USB Offload Playback Route PCM#0'
0, 0 (range -1->255)
This example signifies that the offload path is available over ASoC sound
card index#0 and PCM device#0.
The USB offload kcontrol will be added in addition to the existing
kcontrols identified by the USB SND mixer. The kcontrols used to modify
the USB audio device specific parameters are still valid and expected to be
used. These parameters are not mirrored to the ASoC subsystem.

Add proper checks and updates to the USB substream once receiving a USB QMI
stream enable request. If the substream is already in use from the non
offload path, reject the stream enable request. In addition, update the
USB substream opened parameter when enabling the offload path, so the
non offload path can be blocked.

Several Qualcomm SoCs have a dedicated audio DSP, which has the ability to
support USB sound devices. This vendor driver will implement the required
handshaking with the DSP, in order to pass along required resources that
will be utilized by the DSP's USB SW. The communication channel used for
this handshaking will be using the QMI protocol. Required resources
include:
- Allocated secondary event ring address
- EP transfer ring address
- Interrupter number
The above information will allow for the audio DSP to execute USB transfers
over the USB bus. It will also be able to support devices that have an
implicit feedback and sync endpoint as well. Offloading these data
transfers will allow the main/applications processor to enter lower CPU
power modes, and sustain a longer duration in those modes.
Audio offloading is initiated with the following sequence:
1. Userspace configures to route audio playback to USB backend and starts
playback on the platform soundcard.
2. The Q6DSP AFE will communicate to the audio DSP to start the USB AFE
port.
3. This results in a QMI packet with a STREAM enable command.
4. The QC audio offload driver will fetch the required resources, and pass
this information as part of the QMI response to the STREAM enable command.
5. Once the QMI response is received the audio DSP will start queuing data
on the USB bus.
As part of step#2, the audio DSP is aware of the USB SND card and pcm
device index that is being selected, and is communicated as part of the QMI
request received by QC audio offload. These indices will be used to handle
the stream enable QMI request.

The Qualcomm USB audio offload driver utilizes the QMI protocol to
communicate with the audio DSP. Add the necessary QMI header and field
definitions, so the QMI interface driver is able to route the QMI packet
received to the USB audio offload driver.

In case of notifying SND platform drivers of connection events, some of
these use cases, such as offloading, require an ASoC USB backend device to
be initialized before the events can be handled. If the USB backend device
has not yet been probed, this leads to missing initial USB audio device
connection events.
Expose an API that traverses the usb_chip array for connected devices, and
to call the respective connection callback registered to the SND platform
driver.

With USB audio offloading, an audio session is started from the ASoC
platform sound card and PCM devices. Likewise, the USB SND path is still
readily available for use, in case the non-offload path is desired. In
order to prevent the two entities from attempting to use the USB bus,
introduce a flag that determines when either paths are in use.
If a PCM device is already in use, the check will return an error to
userspace notifying that the stream is currently busy. This ensures that
only one path is using the USB substream.

Within the UAC descriptor, there is information describing the size of a
sample (bSubframeSize/bSubslotSize) and the number of relevant bits
(bBitResolution). Currently, fmt_bits carries only the bit resolution,
however, some offloading entities may also require the overall size of the
sample. Save this information in a separate parameter, as depending on the
UAC format type, the sample size can not easily be decoded from other
existing parameters.

Mixer quicks for the Pioneer DJM-A9 mixer was added in 5289d00 with
additional capture level values added to the common DJM array of values.
This breaks the existing DJM mixers however as alsa-utils relies on
enumeration of the actual mixer options based on the value array which
results in error when storing state.
This commit just separates the A9 values into a separate array and
references them in the corresponding mixer control.

The module parameter defines number of iso packets per one URB. User is
allowed to set any value to the parameter of type int, which can lead to
various kinds of weird and incorrect behavior like integer overflows,
truncations, etc. Number of packets should be a small non-negative number.
Since this parameter is read-only, its value can be validated on driver
probe.
