+TPS65132 regulators
+
+Required properties:
+- compatible: "ti,tps65132"
+- reg: I2C slave address
+
+Optional Subnode:
+Device supports two regulators OUTP and OUTN. A sub node within the
+ device node descrbe the properties of these regulators. The sub-node
+ names must be as follows:
+ -For regulator outp, the sub node name should be "outp".
+ -For regulator outn, the sub node name should be "outn".
+
+-ti,enable-gpio: Regulators are controlled by the input pins. If
+ it is connected to GPIO through host system then provide the
+ gpio number as per gpio.txt.
+-ti,disable-active-discharge: Boolean, presence of this property
+ will disable active discharge on the regulator output.
+-ti,active-discharge-gpio: Some configurations use delay mechanisms
+ on the enable pin, to keep the regulator enabled for some time after
+ the enable signal goes low. This GPIO is used to actively discharge
+ the delay mechanism. Requires specification of ti,active-discharge-time
+-ti,active-discharge-time: how long the active discharge gpio should be
+ asserted for during active discharge, in microseconds.
+
+Each regulator is defined using the standard binding for regulators.
+
+Example:
+
+ tps65132@3e {
+ compatible = "ti,tps65132";
+
+ outp {
+ regulator-name = "outp";
+ regulator-boot-on;
+ regulator-always-on;
+ ti,enable-gpio = <&gpio 23 0>;
+ };
+
+ outn {
+ regulator-name = "outn";
+ regulator-boot-on;
+ regulator-always-on;
+ ti,enable-gpio = <&gpio 40 0>;
+ };
+ };
