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>
2017-05-15edid: Add HDMI flag to timing infoJernej Skrabec
Some DVI monitors don't show anything in HDMI mode since audio stream confuses them. To solve this situation, this commit adds HDMI flag in timing data and sets it accordingly during edid parsing. First existence of extension block is checked. If it exists and it is CEA861 extension, then data blocks are checked for presence of HDMI vendor specific data block. If it is present, HDMI flag is set. Signed-off-by: Jernej Skrabec <jernej.skrabec@siol.net> Reviewed-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>
2015-05-13edid: Add a function to read detailed monitor timingsSimon Glass
For digital displays (such as EDP LCDs) we would like to read the EDID information and use that to set display timings. Provide a function to do this. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>

2013-08-12edid: rename struct member to fix two EDID_* macrosChristian Gmeiner
Without this change EDID_DETAILED_TIMING_VSYNC_OFFSET and EDID_DETAILED_TIMING_VSYNC_PULSE_WIDTH macros can not be used (compile error). The fix is quite trivial: rename struct member to the expected name. Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com>

2012-12-11edid: Library of EDID decode and printTom Wai-Hong Tam
This implements a library for accessing EDID data from an LCD panel. This is used to obtain information about the panel such as its resolution and type. This is a tidied-up version of the original code pulled from https://github.com/ynezz/u-boot-edid. The changes we made are: - removed bit fields in the struct; - removed endianness cases in the struct; - fixed some wrong definitions; - fixed to fit 80 columns; - fixed some code styles.
