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 Signed-off-by: Jim Quinlan <jim2101024@xxxxxxxxx> --- Documentation/devicetree/bindings/pci/brcm,stb-pcie.yaml | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/Documentation/devicetree/bindings/pci/brcm,stb-pcie.yaml b/Documentation/devicetree/bindings/pci/brcm,stb-pcie.yaml index f90557f6deb8..f2caa5b3b281 100644 --- a/Documentation/devicetree/bindings/pci/brcm,stb-pcie.yaml +++ b/Documentation/devicetree/bindings/pci/brcm,stb-pcie.yaml @@ -64,6 +64,9 @@ properties: aspm-no-l0s: true + vpcie12v-supply: true + vpcie3v3-supply: true + brcm,scb-sizes: description: u64 giving the 64bit PCIe memory viewport size of a memory controller.
