Subject: [PATCH v1 0/3] librem5-devkit: Let LED use PWM

So far it used plain GPIO but we can use PWM for brightness control.
While at that use function and color (it's a single color LED) and
enable the pattern led trigger to make it more useful.



Guido Günther (3):
  arm64: defconfig: Enable pattern LED trigger
  arm64: dts: librem5-devkit: Make LED use PWM
  arm64: dts: librem5-devkit: Use function and color rather than label
