[PATCH 11/12] gpu/drm: Ingenic: Add support for the IPU

2020-05-16 Thread Paul Cercueil
Add support for the Image Processing Unit (IPU) found in all Ingenic SoCs. The IPU can upscale and downscale a source frame of arbitrary size ranging from 4x4 to 4096x4096 on newer SoCs, with bicubic filtering on newer SoCs, bilinear filtering on older SoCs. Nearest-neighbour can also be obtained
