   4 Subject: [PATCH] ARM: dts: NSP: MX6X: correct LED function types
   5
   6 Currently, the amber LED will remain always on. This is due to a
   7 misinterpretation of the LED sub-node properties, where-by "default-state"
   8 was used to indicate the initial state when powering on the device. When in
   9 use, however, this resulted in the amber LED always being on. Instead change
  10 this to only indicate a fault state.
  11
  12 Assign LED_FUNCTION_POWER to the green PWM LED.
  13
  14 These changes bring the MX64/65 in line with the MR32's devicetree.
