[PATCH v2 0/4] arm64: dts: qcom: few improvements

[Krzysztof Kozlowski]

Changes in v2:
1. Previous submission included stale patch.  Resend without it. No
actual changes, but marking it v2 for convenience.

Best regards,
Krzysztof

[PATCH v2 1/4] arm64: dts: qcom: sm8450: move Soundwire pinctrl to its nodes

[Krzysztof Kozlowski]

Pin configuration for Soundwire bus should be set in Soundwire
controller nodes, not in the associated macro codec node.  This
placement change should not have big impact in general, because macro
codec is a clock provider for Soundwire controller, thus its devices is
probed first.  However it will have impact for disabled Soundwire buses,
e.g. WSA2, because after this change the pins will be left in default
state.

We also follow similar approach in newer SoCs, like Qualcomm SM8650.

The MCLK clocks of codec macros have fixed 19.2 MHz frequency and
assigning clock rates is redundant.
