Hello,
This patch series is the fifth attempt to (nearly, see [1]) complete the rework of the omapdrm driver to move to drm_bridge and drm_panel.
Version 2, available at [2], explains in its long cover letter the rationale for the changes. I won't duplicate it here as it is still valid as-is.
Compared to v4, available at [3], this version has been rebased on top of drm-next, and support for interlaced modes has been added, fixing a regression in the omapdrm VENC output.
There are multiple options to support interlaced modes, one of them being manual filtering of modes by all bridges in the chain. I decided to instead add an interlace_allowed flag to the drm_bridge structure to simplify the implementation of bridges, the same way drm_connector has a flag with the same name. I'm open to alternative solutions, or extensions to this one, possibly on top of this series.
The patches can be found at

[1] The only notable exception is the omapdrm-specific DSI panel driver that implements a large number of custom operations. This is being addressed separately.
