14 To facilitate the various use cases, the LPG channels can be exposed as
15 individual LEDs, grouped together as RGB LEDs or otherwise be accessed as PWM

35 The pattern is a series of brightness and hold-time pairs, with the hold-time
39 transitions expected by the leds-trigger-pattern format, each entry in the
40 pattern must be followed a zero-length entry of the same brightness.

77 specified hold-time of the middle item in the pattern is allowed to have a
78 different hold-time.
