[PATCH AUTOSEL 5.13 006/219] ASoC: ti: davinci-mcasp: Fix DIT mode support

[Sasha Levin]

From: Peter Ujfalusi <peter.ujfalusi@gmail.com>

[ Upstream commit bbdd3f4dbe81e19b9123bc54e23ed54517615524 ]

The DIT mode support has not been tested due to lack of platform where it
can be tested.
To be able to use the McASP on OMAP4/5 (only supporting DIT mode) we need
to have DIT mode working in the McASP driver on a know platform.
After hacking around (on BBW, mcasp1.axr1 can be routed out for this) it
appeared that DIT mode is broken.

This patch fixes it up and 16/24 bit audio works along with passthrough,
but I have only tested with DTS example and test files.

[PATCH AUTOSEL 5.13 007/219] ASoC: atmel: ATMEL drivers don't need HAS_DMA

[Sasha Levin]

From: Randy Dunlap <rdunlap@infradead.org>

[ Upstream commit 6c5c659dfe3f02e08054a6c20019e3886618b512 ]

On a config (such as arch/sh/) which does not set HAS_DMA when MMU
is not set, several ATMEL ASoC drivers select symbols that cause
kconfig warnings. There is one "depends on HAS_DMA" which is no longer
needed. Dropping it eliminates the kconfig warnings and still builds
with no problems reported.

Fix the following kconfig warnings:

[PATCH AUTOSEL 5.13 086/219] ASoC: Intel: bytcr_rt5640: Move "Platform Clock" routes to the maps for the matching in-/output

[Sasha Levin]

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit dccd1dfd0770bfd494b68d1135b4547b2c602c42 ]

Move the "Platform Clock" routes for the "Internal Mic" and "Speaker"
routes to the intmic_*_map[] / *_spk_map[] arrays.

This ensures that these "Platform Clock" routes do not get added when the
BYT_RT5640_NO_INTERNAL_MIC_MAP / BYT_RT5640_NO_SPEAKERS quirks are used.

[PATCH AUTOSEL 5.13 088/219] ASoC: Intel: update sof_pcm512x quirks

[Sasha Levin]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

[ Upstream commit 22414cade8dfec25ab94df52b3a4f7aa8edb6120 ]

The default SOF topology enables SSP capture and DMICs, even though
both of these hardware capabilities are not always available in
hardware (specific versions of HiFiberry and DMIC kit needed).

For the SSP capture, this leads to annoying "SP5-Codec: ASoC: no
backend capture" and "streamSSP5-Codec: ASoC: no users capture at
close - state 0" errors.

Update the quirks to match what the topology needs, which also allows
for the ability to remove SSP capture and DMIC support.

[PATCH AUTOSEL 5.13 176/219] ASoC: intel: atom: Revert PCM buffer address setup workaround again

[Sasha Levin]

From: Takashi Iwai <tiwai@suse.de>

[ Upstream commit e28ac04a705e946eddc5e7d2fc712dea3f20fe9e ]

We worked around the breakage of PCM buffer setup by the commit
65ca89c2b12c ("ASoC: intel: atom: Fix breakage for PCM buffer address
setup"), but this isn't necessary since the CONTINUOUS buffer type
also sets runtime->dma_addr since commit f84ba106a018 ("ALSA:
memalloc: Store snd_dma_buffer.addr for continuous pages, too").
Let's revert the change again.

[PATCH AUTOSEL 5.13 177/219] soundwire: intel: fix potential race condition during power down

[Sasha Levin]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

[ Upstream commit ea6942dad4b2a7e1735aa0f10f3d0b04b847750f ]

The power down sequence sets the link_up flag as false outside of the
mutex_lock. This is potentially unsafe.

In additional the flow in that sequence can be improved by first
testing if the link was powered, setting the link_up flag as false and
proceeding with the power down. In case the CPA bits cannot be
cleared, we only flag an error since we cannot deal with interrupts
any longer.

[PATCH AUTOSEL 5.13 197/219] ASoC: soc-pcm: protect BE dailink state changes in trigger

[Sasha Levin]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

[ Upstream commit 0c75fc7193387776c10f7c7b440d93496e3d5e21 ]

When more than one FE is connected to a BE, e.g. in a mixing use case,
the BE can be triggered multiple times when the FE are opened/started
concurrently. This race condition is problematic in the case of
SoundWire BE dailinks, and this is not desirable in a general
case. The code carefully checks when the BE can be stopped or
hw_free'ed, but the trigger code does not use any mutual exclusion.

Fix by using the same spinlock already used to check FE states, and
set the state before the trigger. In case of errors,  the initial
state will be restored.

This patch does not change how the triggers are handled, it only makes
sure the states are handled in critical sections.
