Patches 1-7 are mostly generic cleanups, which will grease up the way for bigger changes to be introduced. Patch 3 adds support for a private state structure, which is then used to store state-specific information, which was previously stored in the driver's private structure directly. Patch 10 is the big one; it adds a double-scan feature emulated with DMA descriptors. This trick makes it possible to support a handful of boards which have strange panels with non-square pixels (320x480 4:3). Patch 11 updates the driver to support one top-level bridge per encoder, as it seems to be the norm now.
