[PATCH 00/16] drm/i915: Add support for big joiner on gen11.

[Maarten Lankhorst]

For this to work, we need to split crtc_state in a hw and uapi state.
uapi is what's visible for userspace, hw is what gets committed to
hardware.

In case of planes we use master_plane_state for all properties, and
write the new properties to plane_state.

This patch series is mostly untested and slightly goes against hardware
programming by enabling the master crtc completely before the slave crtc
gets enabled, and still has some bugs in the code as well.

I'm hoping to get some feedback on the approach, as it seems I can make
it work with this. Cursor updates and watermarks are working, cursor
updates only through the slowpath, and planar programming is untested,
but should work.
