Subject: [PATCH 05/17] arm64: dts: imx93-11x11-evk: Add pinmux and mark conflicting devices for MQS1
Date: Fri, 14 Aug 2026 16:20:09 +0900	[thread overview]
Message-ID: <20260814072022.4064009-6-chancel.liu@oss.nxp.com> (raw)
In-Reply-To: <20260814072022.4064009-1-chancel.liu@oss.nxp.com>

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

MQS1 shares pins with PDM 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.
