2015-07-21led: Return -ENODEV if the LED device cannot be foundSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-07-21dm: Add support for LEDsSimon Glass
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>
