Adding RCar DU lib support(Encoder, vsp and KMS) proved that it can save 50% code saving on RZ/G2L compared to patch series [1]. The current patchset contains just movement of codes with some trivial changes. The subsequent patch series will have more additions to vsp and kms library. There is also plan to add library support for DU DRM and DU CRTC (Not yet ready/tested), which will further increase the common code. Current patch set + subsequent patch sets are tested on both RZ/G2M, RZ/G1N and RZ/G2L.
