From: Markus Schneider-Pargmann msp@baylibre.com
This patch adds a DisplayPort driver for the Mediatek mt8195 SoC.
It supports the mt8195, the embedded DisplayPort units. It offers DisplayPort 1.4 with up to 4 lanes.
The driver shares its iomap range with the mtk-dp-phy driver using the regmap/syscon facility.
This driver is based on an initial version by Jason-JH.Lin jason-jh.lin@mediatek.com.

Hello Guillaume,
I think the module author is not Jason-JH Lin. He is the owner of 8195 DRM. The owner should be Jitao Shi jitao.shi@mediatek.com
