* dm: led: Add a driver for GPIO-controlled LEDsSimon Glass2015-07-21-0/+52
| | | | | | | Add a simple driver which allows use of LEDs attached to GPIOs. The linux device tree binding is used. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Add support for LEDsSimon Glass2015-07-21-0/+23
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>
