[v5,00/52] drm/omap: Replace custom display drivers with drm_bridge and drm_panel

Message

Laurent Pinchart Jan. 24, 2020, 3:53 a.m. UTC

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

        git://linuxtv.org/pinchartl/media.git omapdrm/bridge/devel

[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.
