[PATCH v3 0/3] drm/atomic: Allow drivers to write their own plane check for async

Hi,

AMD hardware can do more on the async flip path than just the primary plane, so
to lift up the current restrictions, this patchset allows drivers to write their
own check for planes for async flips.

This patchset allows for async commits with IN_FENCE_ID in any driver and
overlay planes on AMD. Userspace can query if a driver supports this with
TEST_ONLY commits.

Changes from v2:
- Allow IN_FENCE_ID for any driver
- Allow overlay planes again
v2: https://lore.kernel.org/lkml/20240119181235.255060-1-andrealmeid@xxxxxxxxxx/

Changes from v1:
- Drop overlay planes option for now
v1: https://lore.kernel.org/dri-devel/20240116045159.1015510-1-andrealmeid@xxxxxxxxxx/

flips
