14 LED and flash LED devices provide the same basic functionality as current
15 regulators, but extended with LED and flash LED specific features like
16 blinking patterns, flash timeout, flash faults and external flash strobe mode.

48 function-enumerator:
59 deprecated - use 'function' and 'color' properties instead.

160 flash-max-timeout-us:
162 Maximum timeout in microseconds after which the flash LED is turned off.
