This patch adds a DisplayPort driver for the Mediatek mt8195 SoC.
It supports both functional units on the mt8195, the embedded DisplayPort as well as the external DisplayPort units. It offers hot-plug-detection, audio up to 8 channels, and DisplayPort 1.4 with up to 4 lanes.
This driver is based on an initial version by Jason-JH.Lin jason-jh.lin@mediatek.com.
