1*4882a593Smuzhiyun* TPS65912 Power Management Integrated Circuit bindings
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun - compatible		: Should be "ti,tps65912".
5*4882a593Smuzhiyun - reg			: Slave address or chip select number (I2C / SPI).
6*4882a593Smuzhiyun - interrupts		: The interrupt line the device is connected to.
7*4882a593Smuzhiyun - interrupt-controller	: Marks the device node as an interrupt controller.
8*4882a593Smuzhiyun - #interrupt-cells	: The number of cells to describe an IRQ, should be 2.
9*4882a593Smuzhiyun			    The first cell is the IRQ number.
10*4882a593Smuzhiyun			    The second cell is the flags, encoded as trigger
11*4882a593Smuzhiyun			    masks from ../interrupt-controller/interrupts.txt.
12*4882a593Smuzhiyun - gpio-controller	: Marks the device node as a GPIO Controller.
13*4882a593Smuzhiyun - #gpio-cells		: Should be two.  The first cell is the pin number and
14*4882a593Smuzhiyun			    the second cell is used to specify flags.
15*4882a593Smuzhiyun			    See ../gpio/gpio.txt for more information.
16*4882a593Smuzhiyun - regulators:		: List of child nodes that specify the regulator
17*4882a593Smuzhiyun			    initialization data. Child nodes must be named
18*4882a593Smuzhiyun			    after their hardware counterparts: dcdc[1-4] and
19*4882a593Smuzhiyun			    ldo[1-10]. Each child nodes is defined using the
20*4882a593Smuzhiyun			    standard binding for regulators.
