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
18 Many LED devices expose more than one current output that can be connected
19 to one or more discrete LED component. Since the arrangement of connections
20 can influence the way of the LED device initialization, the LED components
21 have to be tightly coupled with the LED device binding. They are represented
22 by child nodes of the parent LED device binding.
27 List of device current outputs the LED is connected to. The outputs are
28 identified by the numbers that must be defined in the LED device binding
34 LED function. Use one of the LED_FUNCTION_* prefixed definitions

83 # LED will act as a back-light, controlled by the framebuffer system
85 # LED will turn on (but for leds-gpio see "default-state" property in
88 # LED "double" flashes at a load average based rate
90 # LED indicates disk activity
92 # LED indicates IDE disk activity (deprecated), in new implementations
95 # LED flashes at a fixed, configurable rate
