+* TPS65912 GPIO Controller bindings
+
+Required properties:
+ - compatible : Should be "ti,tps65912-gpio".
+ - gpio-controller : Marks the device node as a GPIO Controller.
+ - #gpio-cells : Should be two.  The first cell is the pin number and
+     the second cell is used to specify flags.
+     See include/dt-bindings/gpio/gpio.h for possible values.
+
+Example:
+
+	gpio4: tps65912_gpio {
+		compatible = "ti,tps65912-gpio";
+		gpio-controller;
+		#gpio-cells = <2>;
+	};

+* TPS65912 Power Management Integrated Circuit bindings
+
+Required properties:
+ - compatible : Should be "ti,tps65912".
+ - reg : Slave address or chip select number (I2C / SPI).
+ - interrupt-parent : The parent interrupt controller.
+ - interrupts : The interrupt line the device is connected to.
+ - interrupt-controller : Marks the device node as an interrupt controller.
+ - #interrupt-cells: The number of cells to describe an IRQ, this should be 2.
+     The first cell is the IRQ number.
+     The second cell is the flags, encoded as the trigger masks from
+     ../interrupt-controller/interrupts.txt
+
+Additional nodes defined in:
+ - Regulators: ../regulator/tps65912-regulator.txt
