462306a36Sopenharmony_ciDescription:
562306a36Sopenharmony_ci		Specify a software pattern for the LED, that supports altering
662306a36Sopenharmony_ci		the brightness for the specified duration with one software
762306a36Sopenharmony_ci		timer. It can do gradual dimming and step change of brightness.
862306a36Sopenharmony_ci
962306a36Sopenharmony_ci		The pattern is given by a series of tuples, of brightness and
1062306a36Sopenharmony_ci		duration (ms).
1162306a36Sopenharmony_ci
1262306a36Sopenharmony_ci		The exact format is described in:
1362306a36Sopenharmony_ci		Documentation/devicetree/bindings/leds/leds-trigger-pattern.txt

1862306a36Sopenharmony_ciDescription:
1962306a36Sopenharmony_ci		Specify a hardware pattern for the LED, for LED hardware that
2062306a36Sopenharmony_ci		supports autonomously controlling brightness over time, according
2162306a36Sopenharmony_ci		to some preprogrammed hardware patterns. It deactivates any active
2262306a36Sopenharmony_ci		software pattern.
2362306a36Sopenharmony_ci
2462306a36Sopenharmony_ci		Since different LED hardware can have different semantics of
2562306a36Sopenharmony_ci		hardware patterns, each driver is expected to provide its own
2662306a36Sopenharmony_ci		description for the hardware patterns in their documentation
2762306a36Sopenharmony_ci		file at Documentation/leds/.

3262306a36Sopenharmony_ciDescription:
3362306a36Sopenharmony_ci		Specify a pattern repeat number. -1 means repeat indefinitely,
3462306a36Sopenharmony_ci		other negative numbers and number 0 are invalid.
3562306a36Sopenharmony_ci
3662306a36Sopenharmony_ci		This file will always return the originally written repeat
3762306a36Sopenharmony_ci		number.
3862306a36Sopenharmony_ci
3962306a36Sopenharmony_ci		It should be noticed that some leds, like EL15203000 may
4062306a36Sopenharmony_ci		only support indefinitely patterns, so they always store -1.
