[PATCH v2 00/54] R-Car VSP improvements for v4.7

[Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>]

Hello,

This patch series contains all the pending vsp1 driver improvements for v4.7.
In particular, it enables display list usage in non-DRM pipelines (24/54) and
adds support for multi-body display lists (48/54) and the R-Car Gen3 RPF alpha
multiplier (50/54), Z-order control (51/54) and global alpha control (52/54).

The other patches are cleanups, bug fixes and refactoring to support the five
features listed above.

The code is based on top of the "[PATCH v6 0/2] media: Add entity types" patch
series. For convenience I've pushed a branch that contains all the necessary
patches on top of the latest Linux media master branch to

        git://linuxtv.org/pinchartl/media.git vsp1/next

Note that while patch 51/54 and 52/54 enable support for Z-order control and
global alpha control in the vsp1 driver, enabling the features for userspace
requires additional patches for the rcar-du-drm driver. I have pushed a branch
that includes the rcar-du-drm changes and platform enablements to

        git://linuxtv.org/pinchartl/media.git drm/du/vsp1-kms/boards


Changes since v1:

- Fix a typo in the commit message of 03/54
- Base RPF alpha multiplier detection on generation number instead of feature
  flag
- Add patches 52/54 to 54/54
