Subject: [PATCH 1/2] regulator: 88pg86x: add DT bindings document
Date: Fri, 9 Mar 2018 01:53:02 +0300 [thread overview]
Message-ID: <20180308225303.329-1-amonakov@ispras.ru> (raw)
The only device-specific node names are "buck1" and "buck2" for the two
regulators present on the device. Sleep mode GPIO and per-regulator GPIO
enable pins are not exposed (the driver does not support them either).

+Marvell 88PG867/88PG868 voltage regulators
+
+Required properties:
+- compatible: one of "marvell,88pg867", "marvell,88pg868";
+- reg: I2C slave address.
+
+Optional subnodes for regulators: "buck1", "buck2", using common regulator
+bindings given in <Documentation/devicetree/bindings/regulator/regulator.txt>.
+
+Example:
+
+ pg868@19 {
+ compatible = "marvell,88pg868";
+ reg = <0x19>;
+
+ vcpu: buck1 {
+ regulator-boot-on;

+ regulator-min-microvolt = <1000000>;
+ regulator-max-microvolt = <1350000>;
