Add IQaudIO Sound Card support for Raspberry Pi
Set a limit of 0dB on Digital Volume Control
The main volume control in the PCM512x DAC has a range up to
+24dB. This is dangerously loud and can potentially cause massive
clipping in the output stages. Therefore this sets a sensible
limit of 0dB for this control.
Allow up to 24dB digital gain to be applied when using IQAudIO DAC+
24db_digital_gain DT param can be used to specify that PCM512x
codec "Digital" volume control should not be limited to 0dB gain,
and if specified will allow the full 24dB gain.
Modify IQAudIO DAC+ ASoC driver to set card/dai config from dt
Add the ability to set the card name, dai name and dai stream name, from
dt config.

IQaudIO: auto-mute for AMP+ and DigiAMP+
IQAudIO amplifier mute via GPIO22. Add dt params for "one-shot" unmute
and auto mute.
Revision 2, auto mute implementing HiassofT suggestion to mute/unmute
using set_bias_level, rather than startup/shutdown....
"By default DAPM waits 5 seconds (pmdown_time) before shutting down
playback streams so a close/stop immediately followed by open/start
doesn't trigger an amp mute+unmute."
Tested on both AMP+ (via DAC+) and DigiAMP+, with both options...
dtoverlay=iqaudio-dacplus,unmute_amp
"one-shot" unmute when kernel module loads.
dtoverlay=iqaudio-dacplus,auto_mute_amp
Unmute amp when ALSA device opened by a client. Mute, with 5 second delay
when ALSA device closed. (Re-opening the device within the 5 second close
window, will cancel mute.)
Revision 4, using gpiod.
Revision 5, clean-up formatting before adding mute code.
- Convert tab plus 4 space formatting to 2x tab
- Remove '// NOT USED' commented code
Revision 6, don't attempt to "one-shot" unmute amp, unless card is
successfully registered.

Added support for HiFiBerry DAC+
The driver is based on the HiFiBerry DAC driver. However HiFiBerry DAC+ uses
a different codec chip (PCM5122), therefore a new driver is necessary.
Add support for the HiFiBerry DAC+ Pro.
The HiFiBerry DAC+ and DAC+ Pro products both use the existing bcm sound driver with the DAC+ Pro having a special clock device driver representing the two high precision oscillators.
An addition bug fix is included for the PCM512x codec where by the physical size of the sample frame is used in the calculation of the LRCK divisor as it was found to be wrong when using 24-bit depth sample contained in a little endian 4-byte sample frame.
Limit PCM512x "Digital" gain to 0dB by default with HiFiBerry DAC+
24db_digital_gain DT param can be used to specify that PCM512x
codec "Digital" volume control should not be limited to 0dB gain,
and if specified will allow the full 24dB gain.
Add dt param to force HiFiBerry DAC+ Pro into slave mode
"dtoverlay=hifiberry-dacplus,slave"

ASoC: pcm512x: revert downstream changes
This partially reverts commit 185ea05465
which was added by https://github.com/raspberrypi/linux/pull/1152
The downstream pcm512x changes caused a regression, it broke normal
use of the 24bit format with the codec, eg when using simple-audio-card.
The actual bug with 24bit playback is the incorrect usage
of physical_width in various drivers in the downstream tree
which causes 24bit data to be transmitted with 32 clock
cycles. So it's not the pcm512x that needs fixing, it's the
soundcard drivers.

New AudioInjector.net Pi soundcard with low jitter audio in and out.
Contains the sound/soc/bcm ALSA machine driver and necessary alterations to the Kconfig and Makefile.
Adds the dts overlay and updates the Makefile and README.
Updates the relevant defconfig files to enable building for the Raspberry Pi.
Thanks to Phil Elwell (pelwell) for the review, simple-card concepts and discussion. Thanks to Clive Messer for overlay naming suggestions.
Added support for headphones, microphone and bclk_ratio settings.
This patch adds headphone and microphone capability to the Audio Injector sound card. The patch also sets the bit clock ratio for use in the bcm2835-i2s driver. The bcm2835-i2s can't handle an 8 kHz sample rate when the bit clock is at 12 MHz because its register is only 10 bits wide which can't represent the ch2 offset of 1508. For that reason, the rate constraint is added.

ASOC: dwc: Fix 16-bit audio handling
IMO the Synopsys datasheet could be clearer in this area, but it seems
that the DMA data ports (DMATX and DMARX) expect left and right samples
in alternate writes; if a stereo pair is pushed in a single 32-bit
write, the upper half is ignored, leading to double speed audio with a
confused stereo image. Make sure the necessary changes happen by
updating the DMA configuration data in the hw_params method.
The set_bclk_ratio change was made at a time when it looked like it
could be causing an error, but I think the division of responsibilities
is clearer this way (and the kernel log clearer without the info-level

The soundcard drivers originally used snd_pcm_format_physical_width,

in-memory sample storage width should not be a factor in determining
the bclk_ratio. However, the physical width rounds the sample bits up
to the nearest power of 2, which makes it easier to find integer clock
divisors.
Restore the old behaviour, but with an implementation that makes it
clear what is going on.

commit 9f2c0ac142 upstream.
The previous commit 0718a78f6a ("ALSA: usb-audio: Kill timer properly at

However, because the error timer kill added in this patch occurs after the
endpoint delete, a race condition to UAF still occurs, albeit rarely.
Additionally, since kill-cleanup for urb is also missing, freed memory can
be accessed in interrupt context related to urb, which can cause UAF.
Therefore, to prevent this, error timer and urb must be killed before
freeing the heap memory.

[ Upstream commit 44499ecb4f ]
The sanity check previously added to uaudio_transfer_buffer_setup()
assumed the allocated buffer being linear-mapped. But the buffer
allocated via usb_alloc_coherent() isn't always so, rather to be used
with (SG-)DMA API. This leaded to a false-positive warning and the
driver failed to work.
Actually uaudio_transfer_buffer_setup() deals only with the DMA-API
addresses for MEM_XFER_BUF type, while other callers of
uaudio_iommu_map() are with pages with physical addresses for
MEM_EVENT_RING and MEM_XFER_RING types. So this patch splits the
mapping helper function to two different ones, uaudio_iommu_map() for
the DMA pages and uaudio_iommu_map_pa() for the latter, in order to
handle mapping differently for each type. Along with it, the
unnecessary address check that caused probe error is dropped, too.

[ Upstream commit aea3493246 ]
The ALSA HwDep character device of the firewire-motu driver incorrectly
returns EPOLLOUT in poll(2), even though the driver implements no operation
for write(2). This misleads userspace applications to believe write() is
allowed, potentially resulting in unnecessarily wakeups.
This issue dates back to the driver's initial code added by a commit
71c3797779 ("ALSA: firewire-motu: add hwdep interface"), and persisted
when POLLOUT was updated to EPOLLOUT by a commit a9a08845e9 ('vfs: do
bulk POLL* -> EPOLL* replacement("").').
This commit fixes the bug.

commit d5f8458e34 upstream.
The tasdev_load_calibrated_data() function expects the calibration data
values in the cali_data buffer as R0, R0Low, InvR0, Power, TLim which
is not the same as what tas2563_save_calibration() writes to the buffer.
Reorder the EFI variables in the tas2563_save_calibration() function
to put the values in the buffer in the correct order.

commit e5a00dafc7 upstream.
Before conversion to unify the calibration data management, the
tas2563_apply_calib() function performed the big endian conversion and
wrote the calibration data to the device. The writing is now done by the
common tasdev_load_calibrated_data() function, but without conversion.
Put the values into the calibration data buffer with the expected
endianness.

[ Upstream commit cc8e91054c ]
Commit 05f254a636 ("ALSA: usb-audio:
Improve filtering of sample rates on Focusrite devices") changed the
check for max_rate in a way which was overly restrictive, forcing
devices to use very high samplerates if they support them, despite
support existing for lower rates as well.
This maintains the intended outcome (ensuring samplerates selected are
supported) while allowing devices with higher maximum samplerates to be
opened at all supported samplerates.
This patch was tested with a Clarett+ 8Pre USB

soc-generic-dmaengine-pcm.c uses same dev for both CPU and Platform.
In such case, CPU component driver might not have driver->name, then
snd_soc_lookup_component_nolocked() will be NULL pointer access error.
