Simon Glass	fb8a5ffc77	led: Return -ENODEV if the LED device cannot be found ... We normally use -ENODEV for a missing device, rather than -ENOENT. The latter is reserved for when we have a device but cannot find something within it. Also avoid looking at the root LED device since it is only a container.

Simon Glass	5917112c9e	dm: Add support for LEDs ... Add a simple uclass for LEDs, so that these can be controlled by the device tree and activated when needed. LEDs are referred to by their label. This implementation requires a driver for each type of LED (e.g GPIO, I2C). Signed-off-by: Simon Glass <sjg@chromium.org>	2015-07-21 17:39:24 -06:00
