Set is made of one fix for dma-transfer so that result of
dmaengine_submit() is tested before moving on, and few cleanups:
- two non-impactful, where catpt_component_open() layout gets improved
slightly as well as relocation of couple of locals found in
PCM-functions so that they look more cohesive
- no need to expose catpt-driver board-matching information globally.
Most fields are not by it and it's the sole user of haswell_machines
table. By having them locally it is clear what is actually being used

2.25.1
Merge series from Dmitry Osipenko <digetx@gmail.com>:
This series revives Tegra20 S/PDIF driver which was upstreamed long time
ago, but never was used. It also turns Tegra DRM HDMI driver into HDMI
audio CODEC provider. Finally, HDMI audio is enabled in device-trees.
For now the audio is enable only for Acer A500 tablet and Toshiba AC100
netbook because they're already supported by upstream, later on ASUS TF101
tablet will join them.
I based S/PDIF patches on Arnd's Bergmann patch from a separate series [1]
that removes obsolete slave_id. This eases merging of the patches by
removing the merge conflict. This is a note for Mark Brown.
I also based this series on top of power management series [2]. I.e. [2]
should be applied first, otherwise "Add S/PDIF node to Tegra20 device-tree"
patch should have merge conflict. This is a note for Thierry.
[1] https://patchwork.ozlabs.org/project/linux-tegra/list/?series=273312
[2] https://patchwork.ozlabs.org/project/linux-tegra/list/?series=274534
Changelog:
v4: - Added patches that update multi_v7_defconfig with the enabled S/PDIF
and APB DMA drivers.
v3: - Renamed S/PDIF device-tree clocks as was suggested by Rob Herring.
- Added r-bs and acks that were given by Rob Herring to v2.
v2: - Corrected I2S yaml problem that was reported by the DT bot for v1
by removing the non-existent required clock-names property.
- Removed assigned-clocks property from S/PDIF yaml since this property
is now inherited from the clocks property.
- Reordered the "tegra20: spdif: Set FIFO trigger level" patch, making
it the first sound/soc patch in the series, like it was suggested by
Mark Brown in the comment to v1. Also reworded commit message of this
patch to *not* make it looks like it should be backported to stable
kernels.

None of the SOF platforms support INFO_RESUME, and rely on the
indirect path used by the ALSA core with the prepare and TRIGGER_START
steps.
Let's remove the left-over dead code.
The return value of pm_runtime_resume_and_get() needs to be checked to
avoid a usage count imbalance in the error case. This fix is basically
the same as 92c959bae2 ("reset: renesas: Fix Runtime PM usage"),
and the last step before pm_runtime_resume_and_get() can be annotated
as __must_check.

Support new nvidia,fixed-parent-rate device-tree property which instructs
I2S that board wants parent clock rate to stay at a fixed rate. This allows
to play audio over S/PDIF and I2S simultaneously. The root of the problem
is that audio components on Tegra share the same audio PLL, and thus, only
a subset of rates can be supported if we want to play audio simultaneously.
Filter out audio rates that don't match parent clock rate if device-tree
has the nvidia,fixed-parent-rate property.

SPDIF and other SoC components share audio PLL on Tegra, thus only one
component may set the desired base clock rate. This creates problem for
HDMI audio because it uses SPDIF and audio may not work if SPDIF's clock
doesn't exactly match standard audio rate since some receivers may reject
audio in that case. Filter out audio rates which SPDIF output can't
support, assuming that other components won't change rate at runtime.

SND_SOC_SOF_DEVELOPER_SUPPORT contains options affecting how the built
SOF driver stack will behave, enables debug options and other features.
These options have no meaning if the SND_SOC_SOF is not even enabled.
If we have SOF client options under developer_support and debug they can
be selected to be built even without the core, but they do need symbols
from the core (the sof-client API) which can result build failure.
In Kconfig we can have
SND_SOC_SOF_TOPLEVEL=y
SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST=y
for example, which will make the flood client to be built, but the SOF core
is not as SND_SOC_SOF is not selected.

As a preparation for removing all slave_id references from the ALSA code,
remove this one.

the mechanism for configuring DMA would not work as it is implemented,
so this part will get rewritten when the driver gets put into use

if the ctrl_cmd is SOF_CTRL_CMD_BINARY then SOF_CTRL_TYPE_DATA_*
otherwise SOF_CTRL_TYPE_VALUE_CHAN_*.

Set the scontrol->control_data->cmd early to the same as scontrol->cmd.
This is a preparatory patch to remove the ctrl_cmd parameter for the
snd_sof_ipc_set_get_comp_data() function.

The correct ipc_cmd can be selected based on the `ctrl_cmd` and the `set`
parameters:
if the ctrl_cmd is SOF_CTRL_CMD_BINARY then SOF_IPC_COMP_*_DATA
otherwise SOF_IPC_COMP_*_VALUE.
The SET or GET direction can be selected with the use of `set` parameter.

Similar with commit 8a49cd11e6 ("ASoC: SOF: ACPI: avoid reverse
module dependency") we will be having hardware specific drivers that
link against a common "helper" framework.
sof-of-dev.c becomes a library with the interface defined in the newly
created file sof-of-dev.h.

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
We've been adding a 'deep buffer' PCM device to several SOF topologies
in order to reduce power consumption. The typical use-case would be
music playback over a headset: this additional PCM device provides
more buffering and longer latencies, leaving the rest of the system
sleep for longer periods. Notifications and 'regular' low-latency
audio playback would still use the 'normal' PCM device and be mixed
with the 'deep buffer' before rendering on the headphone endpoint. The
tentative direction would be to expose this alternate device to
PulseAudio/PipeWire/CRAS via the UCM SectionModifier definitions.
That seemed a straightforward topology change until our automated
validation stress tests started reporting issues on SoundWire
platforms, when e.g. two START triggers might be send and conversely
the STOP trigger is never sent. The SoundWire stream state management
flagged inconsistent states when the two 'normal' and 'deep buffer'
devices are used concurrently with rapid play/stop/pause monkey
testing.
Looking at the soc-pcm.c code, it seems that the BE state
management needs a lot of love.
a) there is no consistent protection for the BE state. In some parts
of the code, the state updates are protected by a spinlock but in the
trigger they are not. When we open/play/close the two PCM devices in
stress tests, we end-up testing a state that is being modified. That
can't be good.
b) there is a conceptual deadlock: on stop we check the FE states to
see if a shared BE can be stopped, but since we trigger the BE first
the FE states have not been modified yet, so the TRIGGER_STOP is never
sent.
This patchset suggests the removal of the dedicated 'dpcm_lock' and
follows the design suggested by Takashi Iwai. By default the
protection relies on the 'pcm_mutex', except for the FE and BE
triggers where the mutex cannot be used. In this case, the FE PCM
lock is used instead. In the cases where a BE is added/removed, the
pcm_mutex and FE PCM lock are both taken. In addition, the BE PCM
lock is used to serialize access to a shared BE.
With these patches I am able to run our entire validation suite
without any issues with this new 'deep buffer' topology, and no
regressions on existing solutions [1]. The tests were reproduced by
Bard Liao for SoundWire devices.
One might ask 'how come we didn't see this earlier'? The answer is
probably that the .trigger callbacks in most implementations seems to
perform DAPM operations, and sending the triggers multiple times is
not an issue. In the case of SoundWire, we do use the .trigger
callback to reconfigure the bus using the 'bank switch' mechanism. It
could be acceptable to tolerate a trigger multiple times, but the
deadlock on stop cannot be fixed at the SoundWire level alone.
Opens:
1) The issues reported by Nvidia on the RFCv3 may or may not be
present. We'd need test results to make sure the locking update does
not introduce a regression on Tegra.
2) There are other reports of kernel oopses [2] that seem related to
the lack of protection. I'd be good to confirm if this patchset solve
these problems as well.

changes since RFCv3:
Used two patches from Takashi. We now use the pcm_mutex, the FE stream
lock when adding and deleting a BE, and the BE stream lock to handle
concurrency between streams using the same BE.
Added a patch to use GFP_ATOMIC for the DPCM structure.
Fixed PAUSE_RELEASE transition (GitHub comment from Kai Vehmanen)
changes since RFCv2:
Removal of dpcm_lock to use FE PCM locks (credits to Takashi Iwai for
the suggestion). The FE PCM lock is now used before each use of
for_each_dpcm_be() - with the exception of the trigger where the lock
is already taken. This change is also applied in drivers which make
use of this loop (compress, SH, FSL).
Addition of BE PCM lock to deal with mutual exclusion between triggers
for the same BE.
Alignment of the BE atomicity on the FE on connections, this is
required to avoid sleeping in atomic context.
Additional cleanups (indentation, static functions)
changes since RFC v1:
Removed unused function
Removed exported symbols only used in soc-pcm.c, used static instead
Use a mutex instead of a spinlock
Protect all for_each_dpcm_be() loops
Fix bugs introduced in the refcount

A BE connected to more than one FE, e.g. in a mixer case, can go
through the following transitions.
play FE1 -> BE state is START
pause FE1 -> BE state is PAUSED
play FE2 -> BE state is START
stop FE2 -> BE state is STOP (see note [1] below)
release FE1 -> BE state is START
stop FE1 -> BE state is STOP
play FE1 -> BE state is START
pause FE1 -> BE state is PAUSED
play FE2 -> BE state is START
release FE1 -> BE state is START
stop FE2 -> BE state is START
stop FE1 -> BE state is STOP
play FE1 -> BE state is START
play FE2 -> BE state is START (no change)
pause FE1 -> BE state is START (no change)
pause FE2 -> BE state is PAUSED
release FE1 -> BE state is START
release FE2 -> BE state is START (no change)
stop FE1 -> BE state is START (no change)
stop FE2 -> BE state is STOP
The existing code for PAUSE_RELEASE only allows for the case where the
BE is paused, which clearly would not work in the sequences above.
Extend the allowed states to restart the BE when PAUSE_RELEASE is
received, and increase the refcount if the BE is already in START.
[1] the existing logic does not move the BE state back to PAUSED when
the FE2 is stopped. This patch does not change the logic; it would be
painful to keep a history of changes on the FE side, the state machine
is already rather complicated with transitions based on the last BE
state and the trigger type.
