Subject: [PATCH v3 0/5] arm64: qcom: sa8775p: add support for EP PCIe

This series adds the relavent DT bindings, new compatible string,
update PHY, add support to EPF driver and add EP PCIe node in dtsi
file for ep pcie0 controller.

v2 -> v3:
- removed if/then schemas, added minItems for reg,
  reg-bnames, interrupt and interrupt-names instead.
- adding qcom,sa8775p-pcie-ep compitable for sa8775p
  as we have some specific change to add.
- reusing sm8450's pcs_misc num table as it is same as sa8775p.
  used appropriate namespace for pcs.
- remove const from sa8775p_header as kernel test robot
  throwing some warnings due to this.
- remove fallback compatiable as we are adding compatiable for sa8775p.

v1 -> v2:
- update description for dma
- Reusing qcom,sdx55-pcie-ep compatibe so remove compaitable
  for sa8775p
- sort the defines in phy header file and remove extra defines
- add const in return type pci_epf_header and remove MHI_EPF_USE_DMA
  flag as hdma patch is not ready
- add fallback compatiable as qcom,sdx55-pcie-ep, add iommu property

Mrinmay Sarkar (5):
  dt-bindings: PCI: qcom-ep: Add support for SA8775P SoC
  PCI: qcom-ep: Add support for SA8775P SOC
  phy: qcom-qmp-pcie: add endpoint support for sa8775p
  PCI: epf-mhi: Add support for SA8775P
  arm64: dts: qcom: sa8775p: Add ep pcie0 controller node
