2023-03-22drm/mediatek: Modify mediatek-drm for mt8195 multi mmsys supportNancy.Lin
MT8195 have two mmsys. Modify drm for MT8195 multi-mmsys support. The two mmsys (vdosys0 and vdosys1) will bring up two drm drivers, only one drm driver register as the drm device. Each drm driver binds its own component. The last bind drm driver allocates and registers the drm device to drm core. Each crtc path is created with the corresponding drm driver data.

2023-03-22drm/mediatek: Add ovl_adaptor support for MT8195Nancy.Lin
Add ovl_adaptor driver for MT8195. Ovl_adaptor is an encapsulated module and designed for simplified DRM control flow. This module is composed of 8 RDMAs, 4 MERGEs and an ETHDR. Two RDMAs merge into one layer, so this module support 4 layers.

2023-03-22drm/mediatek: Add ETHDR support for MT8195Nancy.Lin
ETHDR is a part of ovl_adaptor. ETHDR is designed for HDR video and graphics conversion in the external display path. It handles multiple HDR input types and performs tone mapping, color space/color format conversion, and then combine different layers, output the required HDR or SDR signal to the subsequent display path.
