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-ep@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/63 Signed-off-by: Jim Quinlan <jim2101024@xxxxxxxxx> --- .../bindings/pci/brcm,stb-pcie.yaml | 23 +++++++++++++++++++ 1 file changed, 23 insertions(+) diff --git a/Documentation/devicetree/bindings/pci/brcm,stb-pcie.yaml b/Documentation/devicetree/bindings/pci/brcm,stb-pcie.yaml index 508e5dce1282..ef2427320b7d 100644 --- a/Documentation/devicetree/bindings/pci/brcm,stb-pcie.yaml +++ b/Documentation/devicetree/bindings/pci/brcm,stb-pcie.yaml @@ -158,5 +158,28 @@ examples: <0x42000000 0x1 0x80000000 0x3 0x00000000 0x0 0x80000000>; brcm,enable-ssc; brcm,scb-sizes = <0x0000000080000000 0x0000000080000000>; + + /* PCIe bridge */ + pci@0,0 { + #address-cells = <3>; + #size-cells = <2>; + reg = <0x0 0x0 0x0 0x0 0x0>; + compatible = "pciclass,0604"; + device_type = "pci"; + vpcie3v3-supply = <&vreg7>; + ranges; + + /* PCIe endpoint */ + pci-ep@0,0 { + assigned-addresses = + <0x82010000 0x0 0xf8000000 0x6 0x00000000 0x0 0x2000>; + reg = <0x0 0x0 0x0 0x0 0x0>; + compatible = "pci14e4,1688"; + #address-cells = <3>; + #size-cells = <2>; + + ranges; + }; + }; }; }; -- 2.17.1
