[PATCH 0/5] omapdrm: fences and zpos

[Laurent Pinchart]

Hello,

This patch series contains two completely unrelated features that just happen
to have been developed one right after the other.

Patches 1/5 to 3/5 implement explicit fences support. The first patch fixes
event handling in the omapdrm driver as required by the atomic commit helper
(and the DRM atomic update API). The second patch replace the hand-rolled
atomic commit handler with the DRM core atomic commit helper, bringing fences
support as a bonus. The third patch then removes the omapdrm custom sync
support that has no user in the mainline kernel.

Patches 4/5 and 5/5 clean up zpos handling by switching to the standard zpos
property implemented in the DRM core. The omapdrm-specific zorder property is
kept for backward compatibility as an alias and should be removed later after
a long enough grace period for userspace to be updated.

As fence support is implemented completely inside the atomic commit helper I
have only tested it lightly using the sw-sync driver. No issue has been
noticed.

The patches are based on top of my previous omapdrm series that has been fully
acked and should thus be merged in v4.11. It also requires the "drm: Constify
drm_mode_config atomic helper private pointer" patch that I have sent to the
dri-devel mailing list today.
