27 The number of drivers is getting big, and driver for on/off LED on a
28 i/o port is really quite different from camera flash LED, which is
29 really different from driver for RGB color LED that can run its own
35 Green-Magenta-Ultraviolet LED, but so far all the LEDs we support are
36 RGB, and not even RGB-White or RGB-Yellow variants emerged.
38 Multicolor is not a good fit for RGB LED. It does not really know
39 about LED color.  In particular, there's no way to make LED "white".
41 Userspace is interested in knowing "this LED can produce arbitrary

50 RGB LEDs are quite common, and it would be good to be able to turn LED
51 white and to turn it into any arbitrary color. It is essential that
