The GCAP register on Tegra234 implies no Input Streams(ISS)
supported, but the HW output stream descriptor programming
should start with offset 0x20*4 from base stream descriptor
address. This will be a problem while calculating the offset
for output stream descriptor which will be considering input
stream also. So here output stream starts with offset 0 which
is wrong as HW register for output stream offset starts with 4.
So hardcode the input stream numbers to 4 to avoid the issue

Implement HDA keep alive (KAE) support for Intel display codecs. When no
audio stream is active, the display codec will provide a continuous clock
and a valid but silent audio stream to any connected HDMI/DP receiver.
Without this, upon starting a new playback stream, initial samples may be
lost as many receivers require time to initialize for new clock.

This is a new feature in Intel AlderLake-P display codec implementation
and replaces the Intel i915 silent-stream extension that has been used
on older hardware. Main benefit of the new method is that codec no longer
needs to be kept in D0 power state.

This patch depends on commit 112a87c4 ("drm/i915/display: program
audio CDCLK-TS for keepalives").

create an identically named control, it can never have loaded without

ASoC: Fixes for v5.18

More fixes that have arrived in the past few -rcs, plus a MAINTAINERS
update.  The biggest update here is the fix for control change
notifications in ASoC generic controls found by mixer-test.

The recently introduced coef_mutex for Realtek codec seems causing a
deadlock when the relevant code is invoked from the power-off state;
then the HD-audio core tries to power-up internally, and this kicks
off the codec runtime PM code that tries to take the same coef_mutex.

In order to avoid the deadlock, do the temporary power up/down around
the coef_mutex acquisition and release.  This assures that the
power-up sequence runs before the mutex, hence no re-entrance will
happen.

The default mixer resume code treats the errors at restoring the
modified mixer items as a fatal error, and it returns back to the
caller.  This ends up in the resume failure, and the device will be
come unavailable, although basically those errors are intermittent and
can be safely ignored.

The problem itself has been present from the beginning, but it didn't
hit usually because the code tries to resume only the modified items.
But now with the recent commit to forcibly initialize each item at the
probe time, the problem surfaced more often, hence it appears as a
regression.

This patch fixes the regression simply by ignoring the errors at
resume.
