Subject: [PATCH v2 0/3] Add audio support on i.MX91 9x9 QSB
Date: Fri, 10 Jul 2026 11:42:01 +0900 [thread overview]
Message-ID: <20260710024204.3462444-1-chancel.liu@oss.nxp.com> (raw)
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 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
