Subject: [PATCH v3 1/6] dt-bindings: PCI: Add bindings for Brcmstb EP voltage regulators
Date: Fri, 26 Mar 2021 15:18:59 -0400 [thread overview]
Message-ID: <20210326191906.43567-2-jim2101024@gmail.com> (raw)
In-Reply-To: <20210326191906.43567-1-jim2101024@gmail.com>
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
