This patch set is in response to Laurent's mail: https://www.spinics.net/lists/dri-devel/msg155618.html So in summary: - The connector is apparently not the right abstraction to carry the detailed timings specification between DRI drivers and bridge drivers. - Instead put detailed timing data into the bridge itself as an optional information pointer. - Add fields to specify triggering edge on the clock, setup and hold time for the bridge. - Augment the dumb VGA driver with this data, supporting a few ADV and TI variants. - Augment the PL111 driver to use this data to figure out if it needs to clock out display data on the negative edge rather than the positive edge because the current clocking out on the positive edge obviously partly misses the setup->hold window, as can be observed in annoying green flicker.
