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.txt)
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:
28 A LED subsystem driver can be controlled also from the level of VideoForLinux2
35 - of_node : of_node of the LED, may be NULL if the same as device's
36 - fled_cdev : LED flash class device to wrap
37 - iled_cdev : LED flash class device representing indicator LED associated with
40 * external_strobe_set - defines the source of the flash LED strobe -
47 LED current scale.
50 * flash_faults - bitmask of flash faults that the LED flash class
53 * torch_intensity - constraints for the LED in TORCH mode
55 * indicator_intensity - constraints for the indicator LED
69 flash API device would. The calls are simply routed to the LED flash API.
