[PATCH] arm64: dts: qcom: sc8280xp-x13s: Add camera activity LED

From: Konrad Dybcio
Date: Sat Aug 05 2023 - 05:01:50 EST


Disappointigly, the camera activity LED is implemented in software.
Hook it up as a gpio-led and (until we have camera *and* a "camera on"
LED trigger) configure it as a panic indicator.
