[PATCH v1 6/6] arm64: dts: librem5-devkit: Move headphone detection to sound card
From: Guido Günther <agx@sigxcpu.org>

linux-devicetree, lkml
Subsystem:
arm/freescale imx / mxc / layerscape arm architecture, the rest · Maintainers:

This allows for automatic output source switching in userspace. Enable the pullup on the GPIO to actually make it trigger and mark it as active-high since detection is reversed otherwise.
