[PATCHv4 3/3] drm: bridge: anx78xx: Add anx78xx driver support by analogix.

Enric Balletbo i Serra
2015-09-25T19:30:06Z

At the moment it only supports ANX7814.

The ANX7814 is an ultra-low power Full-HD (1080p60) SlimPort transmitter
designed for portable devices.

This driver adds initial support and supports HDMI to DP pass-through mode.
