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.

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 first bind drm driver will allocate the drm device, and the last bind drm driver registers the drm device to drm core. Each crtc path is created with the corresponding drm driver data.
