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 Dave's drm-next branch. They can be found at
git://linuxtv.org/pinchartl/media.git omapdrm/bridge/next
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.
Compared to v2, a crash at module removal has been fixed by adding patch 22/61 and rebasing the rest of the series on top of it.
