Subject: [PATCH v3] drm/rockchip: support hwc layer
From: ayaka <ayaka@...lik.info>
The Windows 2/3 or a RGB UI layer is a high performance flexibly
plane. It is too waste to use it as a cursor plane.
I have verified this patch with weston git version, I am not
sure whether X would meet with this patch. As the previous
author is gone, I can't confirm this problem with him.
Also the weston only use the only two achors with a same
size and pixel format, I need more users to verify this
patch.
changelog:
v2: the previous version is mixed with the code for the other
patches, I forget to remove it.
v3: fix the error for the rk3399 vop little.
