drm/msm: Defer VMA unmap for fb unpins
With the conversion to drm_gpuvm, we lost the lazy VMA cleanup, which
means that fb cleanup/unpin when pageflipping to new scanout buffers
immediately unmaps the scanout buffer. This is costly (with tlbinv,
it can be 4-6ms for a 1080p scanout buffer, and more for higher
resolutions)!
To avoid this, introduce a vma_ref, which is incremented whenever
userspace has a GEM handle or dma-buf fd. When unpinning if the
vm is the kms->vm we defer tearing down the VMA until the vma_ref
drops to zero. If the buffer is still part of a flip-chain then
userspace will be holding some sort of reference to the BO, either
via a GEM handle and/or dma-buf fd. So this avoids unmapping the VMA
when there is a strong possibility that it will be needed again.

unmap steps for updating the page tables.
Since, unlike our prior vm/vma setup, with drm_gpuvm the vm_bo holds a
reference to the GEM object. To prevent reference loops causing us to
leak all GEM objects, we implicitly tear down the mapping when the GEM
handle is close or when the obj is unpinned. Which means the submit

DSI PHY PLLs, the parents of pixel and byte clocks, cannot be used as

out to avoid conflict.

fully compatible with earlier SM8650 variant - both are of version
v1.5.1 of the IP block. Datasheet also mentions that both support 4x
MST for DPTX0 and 2x MST for DPTX1.
Add DSI controller for Qualcomm SM8750 SoC which is quite different from
previous (SM8650) generation.
It does not allow the display clock controller clocks like "byte" and
"pixel" to be reparented to DSI PHY PLLs while the DSI PHY PLL is not
configured (not prepared, rate not set). Therefore
assigned-clock-parents are not working here and driver is responsible
for reparenting clocks with proper procedure. These clocks are now
inputs to the DSI controller device.
Except that SM8750 DSI comes with several differences, new blocks and
changes in registers, making it incompatible with SM8650.
