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

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

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.

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

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

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.Signed-off-by: Tom Wai-Hong Tam
