Subject: [RFC RESEND PATCH] drm/rockchip: update cursors asynchronously through atomic.

Add support to async updates of cursors by using the new atomic
interface for that.

Signed-off-by: Enric Balletbo i Serra <[email protected]>
---
I am sending this as RFC because I still don't have a deep knowledge of
the hw and I am not sure if the vop_plane_update function can be reused
in both cases, atomic_updates and atomic_async_updates. I think that
someone with more knowledge should take a look. The patch was tested on
a Samsung Chromebook Plus in two ways.

1. Running all igt kms_cursor_legacy and kms_atomic@plane_cursor_legacy
tests and see that there is no regression after the patch.

2. Running weston using the atomic API.

Best regards,
Enric

LGTM. Given rockchip hasn't weighed in on the patch, and that you've tested it
on real hardware, let's land it.

Your patch don't apply cleanly anymore. Can you rebase it and add the
r-b to the patch while at it? Thanks!
