2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-04-14dm: led: Add support for blinking LEDsSimon Glass
Allow LEDs to be blinked if the driver supports it. Enable this for sandbox so that the tests run. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Ziping Chen <techping.chan@gmail.com>
2017-04-14dm: led: Support toggling LEDsSimon Glass
Add support for toggling an LED into the uclass interface. This can be efficiently implemented by the driver. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Ziping Chen <techping.chan@gmail.com>
2017-04-14dm: led: Add support for getting the state of an LEDSimon Glass
It is useful to be able to read the LED as well as write it. Add this to the uclass and update the GPIO driver. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Ziping Chen <techping.chan@gmail.com>
2017-04-14dm: led: Adjust the LED uclassSimon Glass
At present this is very simple, supporting only on and off. We want to also support toggling and blinking. As a first step, change the name of the main method and use an enum to indicate the state. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Ziping Chen <techping.chan@gmail.com>
2017-04-14dm: led: Rename struct led_uclass_platSimon Glass
These structures are normally named with 'uc' instead of 'uclass'. Change this one for consistency. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Ziping Chen <techping.chan@gmail.com>
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>
