* video: at91: Adjust vidconsole_position_cursor() to use char posSimon Glass2018-10-091-0/+2
| | | | | | | | | | | | At present this function uses pixels but it seems more useful for it to position in terms of characters on the screen. This also matches the comment to the function. Update this. Unfortunately there is one user of this function (at91). Have a crack at fixing this, since I cannot test it.

* ctags: Minor changes to fix ctags outputSimon Glass2018-10-091-1/+2
| | | | | | | | | | At present ctags emits lines with unmatched quotes which means that the output file is invalid. This is with exuberant-ctags version 5.9~svn201103 but I also see it with plain ctags. I am not sure that it is a bug though. Make a few minor changes in the source code to fix this problem.

* panel: Expand the backlight supportSimon Glass2018-10-094-36/+199
| | | | | | | | | | | | At present the panel can be turned on but not off, and the brightness cannot be controlled at run-time. Add a new API function to both the panel and backlight uclasses to handle this. Enhance the PWM backlight driver to deal with custom levels properly and allow the backlight to be turned on and off. Update the test to cover thes new features. Signed-off-by: Simon Glass <sjg@chromium.org>

* sandbox: video: Speed up video outputSimon Glass2018-10-093-10/+10
| | | | | | | | | | | | | | At present there are many situations where sandbox syncs the display to the SDL frame buffer. This is a very expensive operation but is only needed every now and then. Update video_sync() so that we can specify whether this operation is really needed. At present this flag is not used on other architectures. It could also be used for reducing writeback-cache flushes but the benefit of that would need to be investigated.

* dm: video: support more escape sequencesHeinrich Schuchardt2018-09-281-13/+62
| | | | | | | | | | | | | | | | The EFI subsystems needs to know the size of the terminal. If the environment variable stdout = serial,vidconsole this size cannot be read from the video console.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-07107-219/+107
| | | | | | | | | | | | | | | | | | | | 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>
