[PATCH v6 0/3] arm64: dts: qcom: sm8450-hdk: add sound support

[Krzysztof Kozlowski]

Hi,

Changes since v5
================
1. Patch 2:
   - Use different clocks (codec@31e0000, codec@3240000).
   - Order LPASS pinctrl nodes by GPIO number.
   - Add dmic01-default-state and dmic02-default-state to LPASS pinctrl.
2. Patch 3:
   - Use TX_CODEC_DMA_TX_3 for VA capture.
   - Reverse order of speakers (left/right).
   - Drop duplicated wcd-playback-dai-link and add wcd-capture-dai-link.

Changes since v4
================
1. Patch 2:
   - Re-order few properties between Soundwire nodes, to keep them ordered
     consistently.
   - Drop unsupported qcom,port-offset.

Changes since v3
================
1. Re-order reg and sound-dai-cells.

Changes since v2
================
1. Patch 2: Use lower-case hex.
2. Patch 3: Use ACTIVE_LOW for qcom,wcd9380-codec reset-gpios.
   https://lore.kernel.org/all/20221116053817.2929810-11-dmitry.torokhov@gmail.com
3. Add Rb tags.

Changes since v1
================
1. Patch 2:
   - Whitespace cleanups.
   - Correct include - do not use deprecated one.
2. Patch 3:
   - Sort.
   - Add Rb tag.
   - Correct include - do not use deprecated one and drop q6asm.h (not used).

Description
===========
Initial work (still partially in progress) adding audio to HDK8450 board.

Working/tested:
 - speakers
 - one channel of headset

The DTS patches do not have particular dependencies, however they:
1. Use updated ASoC bindings:
   https://lore.kernel.org/linux-arm-msm/20221111113547.100442-1-krzysztof.kozlowski@linaro.org/T/#t

2. For full operation need changes in Soundwire and Qualcomm ASoC drivers, not
   yet upstreamed:
   https://github.com/krzk/linux/commits/wip/sm8450
   Booting remoteproc without these changes will report errors, but these are
   expected at this stage.

Best regards,
Krzysztof

[PATCH v6 3/3] arm64: dts: qcom: sm8450-hdk: add sound support

[Krzysztof Kozlowski]

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

Add sound support to SM8450 HDK board.  Tested setup so far is only two
speakers (working) and head-phones (only one channel working).

Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

Changes since v5:
1. Use TX_CODEC_DMA_TX_3 for VA capture.
2. Reverse order of speakers (left/right).
3. Drop duplicated wcd-playback-dai-link and add wcd-capture-dai-link.

Changes since v3:
1. None.

Changes since v2:
1. Use ACTIVE_LOW for qcom,wcd9380-codec reset-gpios.
   https://lore.kernel.org/all/20221116053817.2929810-11-dmitry.torokhov@gmail.com/

Changes since v1:
1. Sort.
2. Correct include - do not use deprecated one and drop q6asm.h (not
   used).
