[PATCH 07/17] arm64: dts: imx93-14x14-evk: Add pinmux and mark conflicting devices for MQS1

From: Chancel Liu

Date: Fri Aug 14 2026 - 03:22:13 EST


From: Chancel Liu <chancel.liu@xxxxxxx>

MQS1 shares pins with FlexCAN1 and its sound card conflicts with the BT
SCO card. Add the MQS1 pinctrl group and label the conflicting device
and card so the shared imx9-mqs overlay can disable them. The overlay
and its Makefile rule are added in a later patch.
