• 43c6bdd02   edid: Add HDMI flag to timing info ... Browse Code »

  20

  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.

• 2dcf14339   dm: video: Repurpose the 'displayport' uclass to 'display' ... Browse Code »

  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.

  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.

• d46b5f7dc   edid: Library of EDID decode and print ... Browse Code »

  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.
