[v3] Add audio support on i.MX91 9x9 QSB

[PATCH v3 0/3] Add audio support on i.MX91 9x9 QSB

Posted by Chancel Liu 1 week, 5 days ago

From: Chancel Liu <chancel.liu@nxp.com>

The board routes audio related signals through on-board muxes controlled
by a GPIO expander. Add the mux states required by SAI1 playback and PDM
capture. Add support for WM8524 and PDM microphone sound cards in DT.

Changes in v3:
- Fix node ordering: sort root nodes alphabetically by node name, including
  Move wm8524: audio-codec before mux-controller nodes in patch 2
  Move dmic: dmic before mux-controller nodes in patch 3
Link to v2: https://lore.kernel.org/imx/20260710024204.3462444-1-chancel.liu@oss.nxp.com/

Changes in v2:
- Bindings have been applied, remove from this series
- Reorder pinctrl-gpiomux children alphabetically
- Move compatible to be the first property in the wm8524 codec node
- Move vendor property fsl,sai-mclk-direction-output after clock-names
  and before status in the sai1 node
