[PATCH v7 00/54] drm/omap: Replace custom display drivers with drm_bridge and drm_panel

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

This patch series is the sixth 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 v6, available at [3], this version has been rebased on top
of drm-misc-next, and documentation of the bridge overview and operation
usage has been improved. The "drm/omap: dss: Remove unused
omap_dss_device operations" patch has been moved to the end of the
series and isn't meant to be merged yet, as it gets in the way of
Sebastian's DSI rework.

Boris, could you have a look at the small fixes to the drm_bridge
documentation in patches 04/54 and 05/54 ? Daniel, patch 06/54, as well
as the documentation improvements in 07/54 and 09/54 are for you.

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.
