[PATCH 0/4] MT8195 Acer Tomato - Audio support

[PATCH 0/4] MT8195 Acer Tomato - Audio support

[AngeloGioacchino Del Regno]

This series enables full support for audio, with DSP, on the Cherry
Chromebooks.
Related ALSA UCM2 configuration was already merged in its upstream
repository [1]: this is fully tested and working as-is since all of
the required fixes for MT8195 SOF drivers were picked and are present
since `next-20220908`.

_________ Platform overview: _________

What's still missing?

* Format:    feature  (location)
*
* MediaTek vcodec enc/dec (mt8195.dtsi only)
* PCI-Express WiFi card (mt8195 and mt8195-cherry)
* VDOSYS1 (mt8195.dtsi and mediatek-drm/mmsys drivers)
* DP/eDP outputs for external/internal display (mt8195 and mt8195-cherry)
* LVTS Thermal Sensors (mt8195.dtsi, driver is missing)
* GPU support (clocks and mtk-regulator-coupler are awaiting for review/pick)

[PATCH 2/4] arm64: dts: mediatek: cherry: Enable the Audio DSP for SOF

[AngeloGioacchino Del Regno]

This platform is able to use the Audio DSP embedded into the
MT8195 SoC: in preparation for adding audio support for Cherry,
add the ADSP related memory nodes and enable it.

[PATCH 3/4] arm64: dts: mediatek: cherry: Add external codecs and speaker amplifier

[AngeloGioacchino Del Regno]

The entire Cherry family has two digital microphones, for which
we use the generic dmic-codec, linked to the MT6359 PMIC.
Moreover, it uses a Realtek RT1019p amplifier for the speakers
and has either a Realtek RT5682i or RT5682s audio codec on I2C2:
specifically, RT5682i is found on Tomato's rev 1 and rev 2 boards,
while RT5682s is found in rev3 and rev4 boards.

We have to recheck if the firmware that was sent upstream is the right one for
Tomato's dts topology variant, I think.
That's surely a firmware issue that you're seeing, anyway.

Update to this: what you were seeing was not related to this series, which is
entirely correct, but due to an ABI breakage in SoundOpenFirmware.

After I reported that to SOF, a commit [1] was pushed to fix the same - now this
series is fully working, as expected.

https://lore.kernel.org/alsa-devel/20221117232120.112639-1-pierre-louis.bossart@linux.intel.com/T/#u

Chen-Yu, would you please test this again with the aforementioned commit?
Works here, should work for you as well now :-)

Cheers!
Angelo
