The Gen3 R-Car DU devices make use of the VSP to handle frame processing.
In this series we implement support for handling interlaced pipelines by using
the auto-fld feature of the VSP hardware.
The implementation is preceded by some cleanup work and refactoring, through
patches 1 to 6. These are trivial and could be collected earlier and
independently if this series requires further revisions.
Patch 7 makes a key distinctive change to remove all existing support for
headerless display lists throughout the VSP1 driver, and ensures that all
pipelines use the same code path. This simplifies the code and reduces
opportunity for untested code paths to exist.
Patches 8, 9 and 10 implement the relevant support in the VSP1 driver, before
patch 11 finally enables the feature through the drm R-Car DU driver.
This series is based upon my previous TLB optimise and body rework (v8), and is
available from the following URL:

ChangeLog:
v3:
- Rebased on top of TLB Optimise rework v8
- Added the DL parameter back into the configure_partition() calls.
- This change could be moved into the TLB-Optimise series.
- Document interlaced field in struct vsp1_du_atomic_config
v2:
- media: vsp1: use kernel __packed for structures
became:
media: vsp1: Remove packed attributes from aligned structures
- media: vsp1: Add support for extended display list headers
- No longer declares structs __packed
- media: vsp1: Provide support for extended command pools
- Fix spelling typo in commit message
- constify, and staticify the instantiation of vsp1_extended_commands
- s/autfld_cmds/autofld_cmds/
- staticify cmd pool functions (Thanks kbuild-bot)
- media: vsp1: Support Interlaced display pipelines
- fix erroneous BIT value which enabled interlaced
- fix field handling at frame_end interrupt
