But more important: why existing property perst-gpios, > which you already have there in common schema, is not correct for this case? I am confused... Where do you find perst-gpios defined for the rk3399 ? Under Documentation/devicetree/bindings/pci/, the only schema I see using perst-gpios property are for the qcom (Qualcomm) controllers. The RC bindings for the rockchip rk3399 PCIe controller (pci/rockchip,rk3399-pcie.yaml) already define the ep-gpios property. So if anything, this patch should be probably be modified to move this property to the common schema in pci/rockchip,rk3399-pcie-common.yaml.
