I checked the dt-binding file of LPG LED, I will update the dts as 
below, if you think it's correct, I will push v6.

+&pm8350c_pwm {
+       #address-cells = <1>;
+       #size-cells = <0>;
+       status = "okay";
+
+       led@1 {
+               reg = <1>;
+               color = <LED_COLOR_ID_RED>;
+		function = LED_FUNCTION_STATUS;
+       };
+
+       led@2 {
+               reg = <2>;
+               color = <LED_COLOR_ID_GREEN>;
+		function = LED_FUNCTION_STATUS;
+       };
+
+       led@3 {
+               reg = <3>;
+               color = <LED_COLOR_ID_BLUE>;
