This patchset depends on the series "imx8mp: Add media block control"[1] and "i.MX8MP GPC and blk-ctrl"[2] which provide the power driver infrastructure. The Vivante DW100 Dewarp Engine, found on i.MX8MP SoC, provides high-performance dewarp processing for the correction of the distortion that is introduced in images produced by fisheye and wide angle lenses. The engine can be used for accelerating scaling, cropping and pixel format conversion operations independently of the dewarping feature.
