[PATCH v5 0/3] GUD USB Display driver

[Noralf Trønnes]

Hi,

A while back I had the idea to turn a Raspberry Pi Zero into a $5
USB to HDMI/SDTV/DPI display adapter.

The protocol is open so people are free to make displays implementing it and
use this driver, all that's needed is to add a USB vid:pid to the driver for
the display.

See the wiki[1] for more information and images for the Raspberry Pi Zero/4.

Minor changes this time, no protocol changes.

Noralf.
