The existing G2D driver supports only FIMG2D v3 style H/W. This Patch modifies the existing G2D driver to support FIMG2D v4 style H/W. FIMG2D v4 is present in Exynos4x12 and Exynos52x0 boards. Differences between FIMG2Dv3 and FIMG2Dv4: --Default register values for SRC and DST type is different in v4. --The stretching(Scaling) logic is different in v4. --CACHECTRL_REG Register is not present in v4. Even though Exynos4x12 and Exynos52x0 have same FIMG2D v4 H/W, the source clock for fimg2d is present only in Exynos4x12. Exynos52x0 uses only gating clock. So, 3 type-id are defined inside the driver to distinguish between Exynos4210, Exynos4x12 and Exynos52x0.
