In drm_universal_plane_init duplicate pixel formats are given. This change avoids adding duplicate pixel formats by sorting and removing duplicates by comparing with the previously added format. Change-Id: I5ca7fb601cc95ca5093651d016cb38369425c079 Signed-off-by: Mahadevan <quic_mahap@quicinc.com>
This change reverts 'commit d28ebf05f4aa ("disp: msm:
sde: populate WB display encoder list before dsi")'
as drm backend takes first encoder as the primary.

…g completion This change addresses an issue where user space PAGE_FLIP_EVENT expects a vblank timestamp value without enabling vblank. The driver sets the timestamps by enabling vblank in prepare_commit and disabling in complete_commit ensuring user space can issue a new frame on completion of the previous frame.

Supersedes #22, which was automatically closed due to inactivity.
Implemented VBLANK handling during the display commit lifecycle to provide valid PAGE_FLIP_EVENT timestamps to userspace. This enables reliable frame-completion signaling and scheduling of subsequent frames.
Restored DSI and DP encoder priority over the WB encoder to maintain correct primary display-encoder selection and expected display-pipeline behavior.
Optimized DRM plane initialization by removing duplicate pixel-format entries before registration.
