Those pixel formats are used in Synaptics's VideoSmart series SoCs, likes VS640, VS680. I just disclose the pixel formats used in the video codecs and display pipeline this time. Actually any device connected to the MTR module could support those tiling and compressed pixel formats. https://synaptics.com/products/multimedia-solutions Changelog: v5: Moving back the document and rewriting the description. v4: Removed the patches for V4L2, V4L2 would use the drm_fourcc.h .
