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>
2016-11-25video: Track whether a display is in useSimon Glass
Mark a display as in use when display_enable() is called. This can avoid a display being used by multiple video-output devices. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-03-14dm: video: Add a operation to display uclassJacob Chen
The current display class only allow to get timing from edid. So add a operation to get timing directly from driver. In driver, I will use fdtdec_decode_display_timing to get timing. Signed-off-by: Jacob Chen <jacob-chen@iotwrt.com> Acked-by: Simon Glass <sjg@chromium.org>
2016-01-21dm: video: Repurpose the 'displayport' uclass to 'display'Simon Glass
The current DisplayPort uclass is too specific. The operations it provides are shared with other types of output devices, such as HDMI and LVDS LCD displays. Generalise the uclass so that it can be used with these devices as well. Adjust the uclass to handle the EDID reading and conversion to display_timing internally. Also update nyan-big which is affected by this. Signed-off-by: Simon Glass <sjg@chromium.org>
