VPE(Video Processing Engine) is an IP found on DRA7xx, this series adds VPE as a mem to mem v4l2 driver, and VPDMA as a helper library.
The first version of the patch series described VPE in detail, you can have a look at it here: http://www.spinics.net/lists/linux-media/msg66518.html Changes in v4: - Control ID for the driver reserved in v4l2-controls.h - Some fixes/clean ups suggested by Hans. - A small hack done in VPE's probe to use a fixed 64K resource size, this is needed as the DT bindings will split the addresses accross VPE submodules, the driver currently works with register offsets from the top level VPE base. The driver can be modified later to support multiple ioremaps of the sub modules. - Addition of sync on channel descriptors for input DMA channels, this ensures the VPDMA list is stalled in the rare case of an input channel's DMA getting completed after all the output channel DMAs. - Removed the DT and hwmod patches from this series. DRA7xx support is not yet got in the 3.12 merge window. Will deal with those separately.
