Commit 7707f7227f09 ("drm/rockchip: Add support for afbc") switched up the rk3399_vop_big[] register windows, but it did so incorrectly. The biggest problem is in rk3288_win23_data[] vs. rk3368_win23_data[] .format field: RK3288's format: VOP_REG(RK3288_WIN2_CTRL0, 0x7, 1) RK3368's format: VOP_REG(RK3368_WIN2_CTRL0, 0x3, 5) Bits 5:6 (i.e., shift 5, mask 0x3) are correct for RK3399, according to the TRM. There are a few other small differences between the 3288 and 3368 definitions that were swapped in commit 7707f7227f09. I reviewed them to the best of my ability according to the RK3399 TRM and fixed them up. This fixes IOMMU issues (and display errors) when testing with BG24 color formats.
