[PATCH 0/6] Add audio support on i.MX91 9x9 QSB

From: chancel . liu

Date: Tue Jul 07 2026 - 03:05:03 EST


From: Chancel Liu <chancel.liu@xxxxxxx>

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.
