What if we just stuck to color spaces and defined channel curves in the
device tree?

The curve could then be defined via an array of integer pairs, which
would be interpreted as points via which the curve passes and the curve
would be approximated by linear segemts...

led@0 {
colorspace = <COLOR_SPACE_ID_RGB>;
red-curve = <0 0>, <255 255>;
green-curve = <0 0>, <255 128>;
blue-curve = <0 0>, <255 128>;
};
