[PATCH v4 00/12] ASoC: qcom: Add support for SC7180 lpass variant
This patch chain add audio support for SC7180 soc by doing the required modification in existing common lpass-cpu/lpass-platform driver. This also fixes some concurrency issue.
Changes since v3: - Fixed yaml documentation comments and make dt_binding_check issues. - Moved general fixes out of sc7180 specific patches as suggested by Srinivas. - Update clock-names to make it same as existing platforms.

LPASS variants have their own soc specific clocks that needs to be enabled for MI2S audio support. Added a common variable in drvdata to initialize such clocks using bulk clk api. Such clock names is defined in variants specific data and needs to fetched during init.

Why not just get all the clks and not even care about the names of them? Use devm_clk_bulk_get_all() for that, unless some clks need to change rates?
Thanks Stephen for reviewing.

There is ahbix clk which needs clk rate to be set. Please check below patch in
the series for reference

Alright. I wonder if we could make the API better or the binding better and always have the rate settable clk first and then devm_clk_bulk_get_all() could be used along with clk_set_rate() on some array element 0 or something. Anyway, don't mind me, I'm just thinking how to make this simpler.
Ahbix clock is optional clock and not needed for all platforms. Move it to lpass-apq8016/ipq806x as it is not needed for sc7180.

Rohit kumar (8): ASoC: qcom: lpass-cpu: Move ahbix clk to platform specific function ASoC: qcom: lpass-platform: fix memory leak ASoC: qcom: lpass: Use regmap_field for i2sctl and dmactl registers ASoC: qcom: lpass-cpu: fix concurrency issue dt-bindings: sound: lpass-cpu: Add sc7180 lpass cpu node ASoC: qcom: lpass-cpu: Use platform_get_resource ASoC: qcom: lpass-platform: Use platform_get_irq dt-bindings: sound: lpass-cpu: Move to yaml format
Thanks Srini for review and testing.
Mark, I am planning to repost patch07 onwards to address comments by Rob as
there are no comments till patch06 and they are just fixes.
Tested this on Dragon Board 410c!
