  (Krzysztof Kozlowski)

- Add SM8750 compatible to qcom,pcie-sm8550.yaml (Krishna Chaitanya
  Chundru)

- Add Peripheral Virtualization Unit (PVU), which restricts DMA from PCIe
  devices to specific regions of host memory, to the ti,am65 binding (Jan

  Glymur, which is compatible with X1E80100 but doesn't have the
  cnoc_sf_axi clock (Qiang Yu)
