Subject: [PATCH 0/7] qrb4210-rb2: add HDMI audio playback support

First time I am doing anything like this. This series adds
mising pieces here and there to allow addition of sensible
sound card in qrb4210-rb2.dts and enable HDMI audio playback there.

It is planned in future to add support for other outputs and capture --
analog audio support.

The series depends on Srini's sm4250 lpi pinctrl driver:
c2e5a25e8d88 (pinctrl: qcom: Introduce SM4250 LPI pinctrl driver, 2024-06-22)
2ffa7a354662 (dt-bindings: pinctrl: qcom: Add SM4250 pinctrl, 2024-06-22)
As far as I understood it was already accepted and will go through pinctrl tree.

Alexey Klimov (7):
  ASoC: dt-bindings: qcom,sm8250: add qrb4210-rb2-sndcard
  ASoC: qcom: sm8250: add qrb4210-rb2-sndcard compatible string
  ASoC: qcom: sm8250: add handling of secondary MI2S clock
  arm64: dts: qcom: sm6115: add apr, its services and simple sound node
  arm64: dts: qcom: sm6115: add LPASS LPI pin controller
