[PATCH v8 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@chromium.org Rohit kumar rohitkr@codeaurora.org Ajit Pandey ajitp@codeaurora.org But Ajit has left codeaurora. - This patch series needs HDMI DAI name defined in sc7180-lpass.h. 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@google.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.

Use set_jack ops to set jack so machine drivers do not need to include hdmi-codec.h explicitly.

If you would send a newer version, consider changing the name.

hs_jack_of_node and hdmi_jack_of_node are not using. Remove them.

I guess this enumeration has not merged yet? It doesn't sound like a specific-enough naming.

To be neat, move this line immediately before or after "card->dev = dev;".
