267 This option enables support for LEDs driven by a Linear Technology
268 LT3593 controller. This controller uses a special one-wire pulse
269 coding protocol to set the brightness.

284 This option enables trigger support for the leds class.
285 These triggers allow kernel events to drive the LEDs and can
286 be configured via sysfs. If unsure, say Y.
