[PATCH 0/3] PCI: qcom: Binding fix

[Manivannan Sadhasivam <manivannan.sadhasivam@oss.qualcomm.com>]

Hi,

This series fixes the binding issue around the PERST# and PHY properties.
The binding issue was reported in [1], while discussing a DTS fix [2].

The binding fix provided in this series is not sufficient enough to spot all the
shenanigans, especially keeping one property in Controller node and another in
Root Port node. But this series does catch the DTS issue fixed by [2]:

arch/arm64/boot/dts/qcom/sm8750-mtp.dtb: pcie@1c00000 (qcom,pcie-sm8750): 'oneOf' conditional failed, one must be fixed:
	'phys' is a required property
	False schema does not allow [[148, 102, 1]]
	False schema does not allow [[148, 104, 0]]
	from schema $id: http://devicetree.org/schemas/pci/qcom,pcie-sm8550.yaml#
arch/arm64/boot/dts/qcom/sm8750-mtp.dtb: pcie@1c00000 (qcom,pcie-sm8750): pcie@0: 'oneOf' conditional failed, one must be fixed:
	'reset-gpios' is a required property
	'wake-gpios' is a required property
	False schema does not allow [[34]]
	from schema $id: http://devicetree.org/schemas/pci/qcom,pcie-sm8550.yaml#
arch/arm64/boot/dts/qcom/sm8750-mtp.dtb: pcie@1c00000 (qcom,pcie-sm8750): Unevaluated properties are not allowed ('#address-cells', '#interrupt-cells', '#size-cells', 'bus-range', 'device_type', 'dma-coherent', 'interconnect-names', 'interconnects', 'interrupt-map', 'interrupt-map-mask', 'iommu-map', 'linux,pci-domain', 'msi-map', 'msi-map-mask', 'num-lanes', 'operating-points-v2', 'opp-table', 'pcie@0', 'perst-gpios', 'power-domains', 'ranges', 'wake-gpios' were unexpected)
	from schema $id: http://devicetree.org/schemas/pci/qcom,pcie-sm8550.yaml#

Thanks to Dmitry for suggesting the binding fix!
