Hello Teresa, I'm sorry if I was too brief in my review last time, see below. Am Freitag, 11.

Now the label is generated automatically (which is the preferred way), but you did neither add the property "color" nor "function", so the label will be constructed from the node name only. Well I just saw the binding for that LED controller is not converted to yaml yet … Documentation/devicetree/bindings/leds/leds-pca9532.txt Anyways, the modern approach would look like somehow like this: led-0 { function = LED_FUNCTION_ALARM; color = <LED_COLOR_ID_RED>; }; led-1 { function = LED_FUNCTION_STATUS; color = <LED_COLOR_ID_GREEN>; }; led-2 { function = LED_FUNCTION_INDICATOR; color = <LED_COLOR_ID_RED>; function-enumerator = <1>; }; led-3 { function = LED_FUNCTION_INDICATOR; color = <LED_COLOR_ID_RED>; function-enumerator = <2>; }; Hope that helps, for more see Documentation/devicetree/bindings/leds and especially the bindings already converted to yaml. The available macros are in include/dt-bindings/leds/common.h Maybe just add the colors for now, if you're not sure what the function should be. As far as I could see the driver for that LED controller does not yet support multicolor, but I added linux-leds to Cc, maybe someone over there knows more? Sorry to nag about this, but I think it's better to not introduce new dts files with deprecated properties. If that kind of feedback is not desired, please let me know.
