Scaling is supported for every format handled by the frontend. The tiling mode used by the VPU on Allwinner platforms is also supported by this series and a dedicated fourcc modifier is introduced, along with a specific ioctl for allocating tiled buffers. New common fourcc helpers are also introduced in this series, especially related to YUV formats. This was tested on the A33 and A20 platforms and all supported features work properly on both. Framebuffer offsets and source positions are not supported at this point. Changes since v1: * Extended source selected cleanup to both YUV and video channels; * Split and reworded comment about backend scaling; * Sorted newly-introduced lists alphabetically; * Simplified functions to check if a format is supported; * Reworked frontend selection logic as discussed; * Made YUV helpers common, with fourcc and drm_info fashions; * Changed the CREATE_TILED ioctl flags to match the CREATE_DUMB ioctl; * Reworked YUV dimensions calculations to use drm_format_info; * Dropped MB32 part in modifier to match V4L2 definition name; * Improved the description of the tiling modifier; * Avoided splitting CSC coefficients to avoid introducing a new module; * Fixed building the driver as modules; * Various code simplifications and cleanups; * Split commits into logical changes.
