1* TPS65912 Power Management Integrated Circuit bindings
2
3Required properties:
4 - compatible		: Should be "ti,tps65912".
5 - reg			: Slave address or chip select number (I2C / SPI).
6 - interrupts		: The interrupt line the device is connected to.
7 - interrupt-controller	: Marks the device node as an interrupt controller.
8 - #interrupt-cells	: The number of cells to describe an IRQ, should be 2.
9			    The first cell is the IRQ number.
10			    The second cell is the flags, encoded as trigger
11			    masks from ../interrupt-controller/interrupts.txt.
12 - gpio-controller	: Marks the device node as a GPIO Controller.
13 - #gpio-cells		: Should be two.  The first cell is the pin number and
14			    the second cell is used to specify flags.
15			    See ../gpio/gpio.txt for more information.
16 - regulators:		: List of child nodes that specify the regulator
17			    initialization data. Child nodes must be named
18			    after their hardware counterparts: dcdc[1-4] and
19			    ldo[1-10]. Each child nodes is defined using the
20			    standard binding for regulators.
