Hi Krzysztof,
Sorry for the late answer.
The mtk_drm_drv is the component master of the full mediatek drm stack.
it "binds" all of the crtc/dpi/ovl/mutex/merge... components of the stack.
That mtk_ddp_comp_dt_ids array is iterated over to find all of the components
from the device tree.
Hope this clarifies things?
Thx,
Guillaume.
