+* Multicolor LED properties
+
+Bindings for multi color LEDs show how to describe current outputs of
+either integrated multi-color LED elements (like RGB, RGBW, RGBWA-UV
+etc.) or standalone LEDs, to achieve logically grouped multi-color LED
+modules. This is achieved by adding multi-led nodes layer to the
+monochrome LED bindings.
+
+The nodes and properties defined in this document are unique to the multicolor
+LED class.  Common LED nodes and properties are inherited from the common.txt
+within this documentation directory.
+
+Required LED Child properties:
s/Child/child/

Ack



+	- color : For multicolor LED support this property should be defined as
+		  LED_COLOR_ID_MULTI and further definition can be found in
+		  include/linux/leds/common.h.

+led-controller@30 {
+	#address-cells = <1>;
+	#size-cells = <0>;
+	compatible = "ti,lp5024";
+	reg = <0x29>;
+
+	multi-led@1 {
+		#address-cells = <1>;
+		#size-cells = <0>;
+		reg = <1>;
+		color = <LED_COLOR_ID_MULTI>;
+		function = LED_FUNCTION_STATUS;
Status is not too fancy function for multi color LED ;-)
I'd skip it entirely for this example if we don't have
anything suitable at the moment for our disposal.

Not sure I understand.  Status is a good example as a RGB module can be used to present charging status

Unless I misinterpreted your comment.
