This patch adds support for the Primary Plane scaling. On the Amlogic GX SoCs, the primary plane is used as On-Screen-Display layer on top of video, and it's needed to keep the OSD layer to a lower size as the physical display size to : - lower the memory bandwidth - lower the OSD rendering - lower the memory usage This use-case is used when setting the display mode to 3840x2160 and the OSD layer is rendered using the GPU. In this case, the GXBB & GXL cannot work on more than 2000x2000 buffer, thus needing the OSD layer to be kept at 1920x1080 and upscaled to 3840x2160 in hardware. The primary plane atomic check still allow 1:1 scaling, allowing native 3840x2160 if needed by user-space applications.
