ALSA/ASoC/SOF/SoundWire: fix Kconfig issues

In January, Intel kbuild bot and Arnd Bergmann reported multiple
issues with randconfig. This patchset builds on Arnd's suggestions to

a) expose ACPI and PCI devices in separate modules, while sof-acpi-dev
and sof-pci-dev become helpers. This will result in minor changes
required for developers/testers, i.e. modprobe snd-sof-pci will no
longer result in a probe. The SOF CI was already updated to deal with
this module dependency change and introduction of new modules.

b) Fix SOF/SoundWire/DSP_config dependencies by moving the code
required to detect SoundWire presence in ACPI tables to sound/hda.

ASoC: soc-acpi: allow for partial match in parent name

2021-03-02T14:31:06+00:00

To change the module dependencies and simplify Kconfigs, we need to
introduce new driver names (sof-audio-acpi-intel-byt and
sof-audio-acpi-intel-bdw), and move from an exact string match to a
partial one.

ALSA: hda: intel-nhlt: verify config type

2021-03-02T09:22:47+00:00

Multiple bug reports report issues with the SOF and SST drivers when
dealing with single microphone cases.

We currently read the DMIC array information unconditionally but we
don't check that the configuration type is actually a mic array.

When the DMIC link does not rely on a mic array configuration, the
recommendation is to check the format information to infer the maximum
number of channels, and map this to the number of microphones.

This leaves a potential for a mismatch between actual microphones
available in hardware and what the ACPI table contains, but we have no
other source of information.

Note that single microphone configurations can alternatively be
handled with a 'mic array' configuration along with a 'vendor-defined'
geometry.

ASoC: Updates for v5.12

Another quiet release in terms of features, though several of the
drivers got quite a bit of work and there were a lot of general changes
resulting from Morimoto-san's ongoing cleanup work.

 - As ever, lots of hard work by Morimoto-san cleaning up the code and
   making it more consistent.
 - Many improvements in the Intel drivers including a wide range of
   quirks and bug fixes.
 - A KUnit testsuite for the topology code.
 - Support for Ingenic JZ4760(B), Intel AlderLake-P, DT configured
   nVidia cards, Qualcomm lpass-rx-macro and lpass-tx-macro
 - Removal of obsolete SIRF prima/atlas, Txx9 and ZTE zx drivers.

Merge series "Add HDMI support for Intel KeemBay I2S" from Sia Jee Heng :

2021-02-08T15:01:45+00:00

The below patch series are to support Audio over HDMI.
The modification in this patch series shall allow I2S driver
to playback standard PCM format and IEC958 encoded format to
the ADV7511 HDMI chip.

ALSA IEC958 plugin will be used to compose the IEC958 format.

Existing hdmi-codec driver only support standard pcm format.
Support of IEC958 encoded format passdown from ALSA IEC958 plugin
is needed so that the IEC958 encoded data can be streamed to the
HDMI chip.

ALSA: hda: add link_power op to hdac_bus_ops

2021-02-08T14:56:35+00:00

The extended HDA bus (hdac_ext) provides interfaces for more
fine-grained control of individual links than what plain HDA
provides for. Links can be powered off when they are not used and if
all links are released, controller can shut down the command DMA.

These interfaces are currently not used by common HDA codec drivers.
When a HDA codec is runtime suspended, it calls snd_hdac_codec_link_down(),
but there is no link to the HDA extended bus, and on controller side
the links are shut down only when all codecs are suspended.

This patch adds link_power() to hdac_bus ops. Controllers using the HDA
extended core, can use this to plug in snd_hdac_ext_bus_link_power() to
implement more fine-grained control of link power.

No change is needed for plain HDA controllers nor to existing HDA
codec drivers.

ASoC: audio-graph: Rename functions needed for export

2021-02-08T11:39:50+00:00

Following functions are renamed for a better global visibility.
  graph_card_probe() --> audio_graph_card_probe()
  graph_parse_of()   --> audio_graph_parse_of()
  graph_remove()     --> audio_graph_remove() [exported as well]

The references of these are updated in audio graph and Tegra audio
graph card drivers.
