[00/14] plane update with damage

Message

Hi,

Set of patches for a new plane property FB_DAMAGE_CLIPS to send damage during
plane update. I have incorporated review comments since last RFC. Also with
this patch series vmwgfx implementation of plane damage.

Based on Rob Clark earlier patch, implemented legacy dirtyfb with new damage
clips property.

I will be sending a separate patch series for unit test case for damage
interface using igt-gpu-tools. Also a separate patch series for a rudimentary
weston implementation, which for now only send damage for default scanout plane.

Testing: vmware xorg driver mainly use dirty_fb ioctl to update the screen so
it is a good overall test of damage interface. Weston implementation also works
as intended.

Let me know what you think. Thanks,
Deepak
