[PATCH AUTOSEL 5.9 01/55] ASoC: mediatek: mt8183-da7219: fix DAPM paths for rt1015

[Sasha Levin]

From: Tzung-Bi Shih <tzungbi@google.com>

[ Upstream commit eb5a558705c7f63d06b4ddd072898b1ca894e053 ]

RT1015's output widget name is "SPO" instead of "Speaker".  Fixes it to
use the correct names.

[PATCH AUTOSEL 5.9 02/55] ASoC: qcom: sdm845: set driver name correctly

[Sasha Levin]

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

[ Upstream commit 3f48b6eba15ea342ef4cb420b580f5ed6605669f ]

With the current state of code, we would endup with something like
below in /proc/asound/cards for 2 machines based on this driver.

Machine 1:
 0 [DB845c            ]: DB845c - DB845c
                       DB845c
Machine 2:
 0 [LenovoYOGAC6301]: Lenovo-YOGA-C63 - Lenovo-YOGA-C630-13Q50
                     LENOVO-81JL-LenovoYOGAC630_13Q50-LNVNB161216

This is not very UCM friendly both w.r.t to common up configs and
card identification, and UCM2 became totally not usefull with just
one ucm sdm845.conf for two machines which have different setups
w.r.t HDMI and other dais.

Reasons for such thing is partly because Qualcomm machine drivers never
cared to set driver_name.

This patch sets up driver name for the this driver to sort out the
UCM integration issues!

after this patch contents of /proc/asound/cards:

Machine 1:
 0 [DB845c         ]: sdm845 - DB845c
                      DB845c
Machine 2:
 0 [LenovoYOGAC6301]: sdm845 - Lenovo-YOGA-C630-13Q50
                     LENOVO-81JL-LenovoYOGAC630_13Q50-LNVNB161216

with this its possible to align with what UCM2 expects and we can have
sdm845/DB845.conf
sdm845/LENOVO-81JL-LenovoYOGAC630_13Q50-LNVNB161216.conf
... for board variants. This should scale much better!

[PATCH AUTOSEL 5.9 03/55] ASoC: cs42l51: manage mclk shutdown delay

[Sasha Levin]

From: Olivier Moysan <olivier.moysan@st.com>

[ Upstream commit 20afe581c9b980848ad097c4d54dde9bec7593ef ]

A delay must be introduced before the shutdown down of the mclk,
as stated in CS42L51 datasheet. Otherwise the codec may
produce some noise after the end of DAPM power down sequence.
The delay between DAC and CLOCK_SUPPLY widgets is too short.
Add a delay in mclk shutdown request to manage the shutdown delay
explicitly. From experiments, at least 10ms delay is necessary.
Set delay to 20ms as recommended in Documentation/timers/timers-howto.rst
when using msleep().

[PATCH AUTOSEL 5.9 11/55] ALSA: hda: Separate runtime and system suspend

[Sasha Levin]

From: Kai-Heng Feng <kai.heng.feng@canonical.com>

[ Upstream commit f5dac54d9d93826a776dffc848df76746f7135bb ]

Both pm_runtime_force_suspend() and pm_runtime_force_resume() have
some implicit checks, so it can make code flow more straightforward if
we separate runtime and system suspend callbacks.

High Definition Audio Specification, 4.5.9.3 Codec Wake From System S3
states that codec can wake the system up from S3 if WAKEEN is toggled.
Since HDA controller has different wakeup settings for runtime and
system susend, we also need to explicitly disable direct-complete which
can be enabled automatically by PCI core. In addition to that, avoid
waking up codec if runtime resume is for system suspend, to not break
direct-complete for codecs.

While at it, also remove AZX_DCAPS_SUSPEND_SPURIOUS_WAKEUP, as the
original bug commit a6630529aecb ("ALSA: hda: Workaround for spurious
wakeups on some Intel platforms") solves doesn't happen with this
patch.
