This series introduce a macro to generate a function to read simple formats. It avoid duplication of the same logic for similar formats.
In addition, it also introduce multiple "easy" formats (rgb888 variants) and also 16 bits yuv support (P01* formats). PATCH 1 is the introduction of the macro and adaptation of the existing code to avoid duplication PATCH 2-5 introduce new formats with the help of this macro. PATCH 6 adds support for 16-bit yuv formats PATCH 7 introduces a macro to reduce code duplication between yuv formats PATCH 8 adds support for P01* formats I tested the implementation using kms_plane.
