Subject[PATCH v4 2/6] dt-bindings: PCI: Add bindings for Brcmstb endpoint device voltage regulators
Date
Similar to the regulator bindings found in "rockchip-pcie-host.txt", this
allows optional regulators to be attached and controlled by the PCIe RC
driver. That being said, this driver searches in the DT subnode (the EP
node, eg pci@0,0) for the regulator property.

The use of a regulator property in the pcie EP subnode such as
"vpcie12v-supply" depends on a pending pullreq to the pci-bus.yaml
file at

https://github.com/devicetree-org/dt-schema/pull/54
