Simon Glass	3c43fba3d2	dm: test: Add a test for the LED uclass Add a test to confirm that we can adjust LEDs using the led_gpio driver. Signed-off-by: Simon Glass <sjg@chromium.org>	10 years ago
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	5ac76bad22	dm: led: Add a driver for GPIO-controlled LEDs 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>	10 years ago
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>	10 years ago
