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 (v7), and is available from the following URL:

ChangeLog:
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
Kieran Bingham (11): media: vsp1: drm: Fix minor grammar error media: vsp1: Remove packed attributes from aligned structures media: vsp1: Rename dl_child to dl_next media: vsp1: Remove unused display list structure field media: vsp1: Clean up DLM objects on error media: vsp1: Provide VSP1 feature helper macro media: vsp1: Use header display lists for all WPF outputs linked to the DU media: vsp1: Add support for extended display list headers media: vsp1: Provide support for extended command pools media: vsp1: Support Interlaced display pipelines drm: rcar-du: Support interlaced video output through vsp1
