Hello,
This patch series is the second version of the second (and most probably last) round of vsp1 driver improvements for v4.7. In particular, it enables runtime PM support (03/13 and 04/13), adds support for the FCP (01/13, 02/13 and 05/13), prepare for HGO (histogram) support (06/13 to 09/13) and update the API towards the DRM driver (10/13 to 13/13).
The FCP is a companion module of video processing modules in the Renesas R-Car Gen3 SoCs. It provides data compression and decompression, data caching, and conversion of AXI transaction in order to reduce the memory bandwidth. The FCP driver is not meant to be used standalone but provides an API to the video processing modules to control the FCP.
The API towards the DRM driver is updated to store all configuration parameters in a structure in order to improve readability and make future updates easier. This series contain two R-Car DU DRM patches that update the DU DRM driver to the new API. They would normally be merged through Dave Airlie's tree, but due to dependencies on VSP1 patches queued up for v4.7 Dave agreed to get them merged through the linux-media tree (hence his Acked-by for the two patches). They should not conflict with any patch queued up for v4.7 through Dave's tree.
Note that patch 10/13 adds some macro magic to make the API transition easier. Depending on your taste you will find the implementation beautiful or ugly, but in any case patch 13/13 removes the macros and inline wrapper.
The code is based on top of the latest linux-media master branch. For convenience I've pushed the patches to the following git tree branch. patches on top of the latest Linux media master branch to

Changes since v1:
- Fixed typos - Made rcar_fcp_enable() return a status - Dropped the unneeded dependency on PM for the VSP driver
