From: "Hsia-Jun(Randy) Li" <randy.li@xxxxxxxxxxxxx> 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: v6: Refresh and fix warnings in its document. v5: Moving back the document and rewriting the description. v4: Removed the patches for V4L2, V4L2 would use the drm_fourcc.h . Moving the documents to the mesa project. v3: There was a mistake in format macro. Correcting the description of 64L4 variant modifiers. v2: The DRM modifiers in the first draft is too simple, it can't tell the tiles in group attribute in memory layout. Removing the v4l2 fourcc.
