A video bridge typically converts video from one format to another, e.g. DisplayPort to LVDS. Add driver model support for these with a simple interface to control activation and backlight. The uclass supports GPIO control of power and reset lines. Signed-off-by: Simon Glass <sjg@chromium.org>

Turn on this option to enable a very simple driver which uses vesa
|
|
to discover the video mode and then provides a frame buffer for use
|
|
by U-Boot. This can in principle be used with any platform that
|
|
supports PCI and video cards that support VESA BIOS Extension (VBE).
