[PATCH AUTOSEL 6.7 06/44] ASoC: amd: acp: Add check for cpu dai link initialization

[Sasha Levin]

From: Venkata Prasad Potturu <venkataprasad.potturu@amd.com>

[ Upstream commit 6cc2aa9a75f2397d42b78d4c159bc06722183c78 ]

Add condition check for cpu dai link initialization for amplifier
codec path, as same pcm id uses for both headset and speaker path
for RENOIR platforms.

[PATCH AUTOSEL 6.7 11/44] ALSA: hda: Increase default bdl_pos_adj for Apollo Lake

[Sasha Levin]

From: Rui Salvaterra <rsalvaterra@gmail.com>

[ Upstream commit 56beedc88405fd8022edfd1c2e63d1bc6c95efcb ]

Apollo Lake seems to also suffer from IRQ timing issues. After being up for ~4
minutes, a Pentium N4200 system ends up falling back to workqueue-based IRQ
handling:

[  208.019906] snd_hda_intel 0000:00:0e.0: IRQ timing workaround is activated
for card #0. Suggest a bigger bdl_pos_adj.

Unfortunately, the Baytrail and Braswell workaround value of 32 samples isn't
enough to fix the issue here. Default to 64 samples.

The SPDIF hardware block found in the H616 SoC has the same layout as
the one found in the H6 SoC, except that it is missing the receiver
side.

Since the driver currently only supports the transmit function, support
for the H616 is identical to what is currently done for the H6.

[PATCH AUTOSEL 6.7 29/44] ASoC: wm_adsp: Don't overwrite fwf_name with the default

[Sasha Levin]

From: Richard Fitzgerald <rf@opensource.cirrus.com>

[ Upstream commit daf3f0f99cde93a066240462b7a87cdfeedc04c0 ]

There's no need to overwrite fwf_name with a kstrdup() of the cs_dsp part
name. It is trivial to select either fwf_name or cs_dsp.part as the string
to use when building the filename in wm_adsp_request_firmware_file().

This leaves fwf_name entirely owned by the codec driver.

It also avoids problems with freeing the pointer. With the original code
fwf_name was either a pointer owned by the codec driver, or a kstrdup()
created by wm_adsp. This meant wm_adsp must free it if it set it, but not
if the codec driver set it. The code was handling this by using
devm_kstrdup().
But there is no absolute requirement that wm_adsp_common_init() must be
called from probe(), so this was a pseudo-memory leak - each new call to
wm_adsp_common_init() would allocate another block of memory but these
would only be freed if the owning codec driver was removed.

[PATCH AUTOSEL 6.7 30/44] ALSA: usb-audio: Ignore clock selector errors for single connection

[Sasha Levin]

From: Alexander Tsoy <alexander@tsoy.me>

[ Upstream commit eaa1b01fe709d6a236a9cec74813e0400601fd23 ]

For devices with multiple clock sources connected to a selector, we need
to check what a clock selector control request has returned. This is
needed to ensure that a requested clock source is indeed selected and for
autoclock feature to work.

For devices with single clock source connected, if we get an error there
is nothing else we can do about it. We can't skip clock selector setup as
it is required by some devices. So lets just ignore error in this case.

This should fix various buggy Mackie devices:

[  649.109785] usb 1-1.3: parse_audio_format_rates_v2v3(): unable to find clock source (clock -32)
[  649.111946] usb 1-1.3: parse_audio_format_rates_v2v3(): unable to find clock source (clock -32)
[  649.113822] usb 1-1.3: parse_audio_format_rates_v2v3(): unable to find clock source (clock -32)

There is also interesting info from the Windows documentation [1] (this
is probably why manufacturers dont't even test this feature):

"The USB Audio 2.0 driver doesn't support clock selection. The driver
uses the Clock Source Entity, which is selected by default and never
issues a Clock Selector Control SET CUR request."
