Subject: [PATCH v4 2/6] dt-bindings: PCI: Add bindings for Brcmstb endpoint device voltage regulators
Date: Thu,  1 Apr 2021 17:21:42 -0400	[thread overview]
Message-ID: <20210401212148.47033-3-jim2101024@gmail.com> (raw)
In-Reply-To: <20210401212148.47033-1-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
