edid: Use sizeof() in cea_is_hdmi_vsdb_present()

We should not use an open-coded value here. Use sizeof() instead.

edid: Add HDMI flag to timing info

2017-05-15T18:32:12+00:00

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.

edid: Set timings flags according to edid

2017-05-15T18:28:12+00:00

Timing flags are never set, so they may contain garbage. Since some
drivers check them, video output may be broken on those drivers.

Initialize them to 0 and check for few common flags.

edid: Add a function to read detailed monitor timings

2015-05-13T16:24:10+00:00

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.

edid: Library of EDID decode and print

2012-12-11T20:17:34+00:00

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.
