SubjectAW: [PATCH v2 1/2] dt-bindings: leds: Add multi-color default-intensities property
Date
Hello Sven,

tried this some time ago for the LP50XX
https://lore.kernel.org/all/20210204143726.27977-1-schuchmann@schleissheimer.de/

Your solution looks much better.
Could you give an example of how to use it?

My Configuration at this time looks like this:

multi-led@0 {
#address-cells = <1>;
#size-cells = <0>;
reg = <0x0>;
color = <LED_COLOR_ID_RGB>;
function = "eee-led-status";

led-0 {
color = <LED_COLOR_ID_RED>;
};

led-1 {
color = <LED_COLOR_ID_GREEN>;
};

led-2 {
color = <LED_COLOR_ID_BLUE>;
};
};


Where do I put the "default-intensities"?

Regards,

Sven
