It has two mutually exclusive background planes (same Z level) + one overlay plane.
What's the difference between the two background planes?
How will generic userspace know to pick the "right" one?
First primary plane cannot scale, supports RGB and C8. Second primary plane goes through the IPU, and as such can scale and convert pixel formats; it supports RGB, non-planar YUV, and multi-planar YUV.
Right now the userspace apps we have will simply pick the first one that fits the bill.

The ingenic-drm driver has two mutually exclusive primary planes already; so the fact that a CRTC must have one and only one

plane is an invalid assumption.
Why does this driver expose two primary planes, if it only has a single CRTC?
