[PATCH v4 0/3] drm/bridge: Add it66121 driver

[Neil Armstrong]

The IT66121 is a high-performance and low-power single channel HDMI
transmitter, fully compliant with HDMI 1.3a, HDCP 1.2 and backward
compatible to DVI 1.0 specifications.
It supports pixel rates from 25MHz to 165MHz.

This series contains document bindings, add vendor prefix, Kconfig to
enable or not.
For now, the driver handles only RGB without color conversion.
