Subject: [PATCH v11 0/3] Add documentation and machine driver for SC7180 sound card

Note:
- The machine driver patch is made by the collaboration of
  Cheng-Yi Chiang <cychiang@...omium.org>
  Rohit kumar <rohitkr@...eaurora.org>
  Ajit Pandey <ajitp@...eaurora.org>
  But Ajit has left codeaurora.
- This patch series needs HDMI DAI name SC7180_LPASS_DP defined in sc7180-lpass.h.
  It will be posted in the newer patchset of https://patchwork.kernel.org/patch/11745565/

Changes from v1 to v2:
- Ducumentation: Addressed all suggestions from Doug.
- Machine driver:
  - Fix comment style for license.
  - Sort includes.
  - Remove sc7180_snd_hw_params.
  - Remove sc7180_dai_init and use aux device instead for headset jack registration.
  - Statically define format for Primary MI2S.
  - Atomic is not a concern because there is mutex in card to make sure
    startup and shutdown happen sequentially.
  - Fix missing return -EINVAL in startup.
  - Use static sound card.
  - Use devm_kzalloc to avoid kfree.

Changes from v2 to v3:
- Ducumentation: Addressed suggestions from Srini.
- Machine driver:
  - Reuse qcom_snd_parse_of to parse properties.
  - Remove playback-only and capture-only.
  - Misc fixes to address comments.

Changes from v3 to v4:
- Ducumentation: Addressed suggestions from Rob.
 - Remove definition of dai.
 - Use 'sound-dai: true' for sound-dai schema.
 - Add reg property to pass 'make dt_binding_check' check although reg is not used in the driver.
- Machine driver:
 - Add Reviewed-by: Tzung-Bi Shih <tzungbi@...gle.com>

Changes from v4 to v5:
- Documentation: Addressed suggestions from Rob.
 - Add definition for "#address-cells" and "#size-cells".
 - Add additionalProperties: false
 - Add required properties.

Changes from v5 to v6:
- Documentation: Addressed suggestions from Rob.
 - Drop contains in compatible strings.
 - Only allow dai-link@[0-9]
 - Remove reg ref since it has a type definition already.

Changes from v6 to v7
- Documentation:
  - Add headset-jack and hdmi-jack to specify the codec
    responsible for jack detection.
- HDMI codec driver:
  - Use component set_jack ops instead of exporting hdmi_codec_set_jack_detect.
- Machine driver:
  - Removed aux device following Stephan's suggestion.
  - Use headset-jack and hdmi-jack to specify the codec
    responsible for jack detection.
  - Add support for HDMI(actually DP) playback.

Changes from v7 to v8
- Documentation:
  - Remove headset-jack and hdmi-jack.
- Machine driver:
  - Let machine driver decide whether there is a jack on the DAI.

Changes from v8 to v9
- hdmi-codec driver:
  - Fixed the naming.
- Machine driver:
  - Fixed unused fields.
  - Moved snd_soc_card_set_drvdata
  - Keep the naming of HDMI as dai name until v5 of lpass-hdmi patches.

Changes from v9 to v10
- Documentation:
  - Let compatible string be more specific for board configuration to allow
    for future changes.
- Machine driver:
  - Fixed unused include and macro.
  - Add temporary macro SC7180_LPASS_DP for future change in sc7180-lpass.h.
  - Let sound card be dynamically allocated.
  - Change compatible string accordingly.

Changes from v10 to v11
- Machine driver:
  - Use temporary macro LPASS_DP_RX for future change in sc7180-lpass.h.
