+================
+Synaptics Tiling
+================
+
+The tiling pixel formats in Synpatics Video Smart platform have
+many variants. Tiles could form the group of tiles(GOT), pixels
+within a group rectangle are stored into tile.
+There are two parameters which consist a modifier described
+the (nearest) width and height pixels in a group.
+
+Meanwhile, the tile in a group may not follow dimension
+layout, tile could form a small group of tiles, then that (sub)group
+of tiles would form a bigger group. We won't describe the dimension
+layout inside the group of tiles here. The layout of the group
+of tiles is fixed with the group width and height parameters
+in the same generation of the platform.
+
+Compression
+===========
+The proprietary lossless image compression protocol in Synaptics
+could minimizes the amount of data transferred (less memory bandwidth
+consumption) between devices. It would usually apply to the tiling
+pixel format.
+
+Each component would request an extra page aligned length buffer
+for storing the compression meta data. Also a 32 bytes parameters
+set would come with a compression meta data buffer.
+
+The component here corresponds to a signal type (i.e. Luma, Chroma).
+They could be encoded into one or multiple metadata planes, but
+their compression parameters would still be individual.
+
+Pixel format modifiers
+======================
+Addition alignment requirement for stride and size of a memory plane
+could apply beyond what has been mentioned below. Remember always
+negotiating with all the devices in pipeline before allocation.
