[PATCH v2 2/6] arm64: dts: imx8mq-librem5: add RGB pwm notification leds

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Guido Günther <agx@xxxxxxxxxxx>

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.
