2 Flash LED handling under Linux
5 Some LED devices provide two modes - torch and flash. In the LED subsystem
6 those modes are supported by LED class (see Documentation/leds/leds-class.rst)
7 and LED Flash class respectively. The torch mode related features are enabled
12 must be defined in the kernel config. A LED Flash class driver must be
13 registered in the LED subsystem with led_classdev_flash_register function.
15 Following sysfs attributes are exposed for controlling flash LED devices:
