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