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.

165 Maximum timeout in microseconds after which the flash LED is turned off.
166 Required for flash LED nodes with configurable timeout.
