Hello,
This patch series is a first step towards moving the omapdrm driver away from
the custom bridge and panel drivers to drm_bridge and drm_panel.
The main blocker to transition to drm_bridge and drm_panel is the direction of
the bridge operations. While the omapdrm driver manages its components from
sink to source (panel to DSS output), the drm_bridge API is manages bridges in
the source to sink direction. This makes the two models incompatible, and
requires reversing the direction of operations inside omapdrm.
Don't rejoice too fast, we're still far from a complete transition, but this
first step paves the way by reworking the driver's internals to make source to
sink order possible. It then transitions the connect and disconnect operations
(the omapdrm equivalent of the drm_bridge attach and detach operations) to the
new direction.
The series contains patches previously posted by Jyri and Peter that I have
found helpful. Please see the individual patches for changes compared to the
original versions (trivial conflict resolutions caused by a rebase are not
mentioned).
The patches are based on top of the "[PATCH v2 0/6] omapdrm: struct_mutex
removal" patch series I've sent yesterday, itself based on top of Dave's
drm-next branch. They can be found at
git://linuxtv.org/pinchartl/media.git omapdrm/bridge
The series has been tested on a Pandaboard with the HDMI and DVI outputs, and
on a TI AM57xx EVM with the LCD and HDMI outputs. All patches have been tested
individually on the Pandaboard.
Compared to v1, patch "drm/omap: dss: Remove omapdss_hdmi_ops set_infoframe
operation" has been dropped, and patch "drm/omap: dss: Handle DPI and SDI port
initialization failures" added. Other small changes are documented in
individual patches.
