Re: [PATCH v1 2/5] arm64: dts: imx8mq-librem5: add RGB pwmleds

From: Guido Günther <agx@sigxcpu.org>

Describe the RGB notification leds on the Librem 5 phone.
Use the common defines so we're sure to adhere to the common patterns,
use predefined led colors and functions so we're being warned in case
of deprecations.
