* 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, should be 2.
|
|
The first cell is the IRQ number.
|
|
The second cell is the flags, encoded as trigger
|
|
masks from ../interrupt-controller/interrupts.txt.
|
|
- 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 ../gpio/gpio.txt for more information.
|
|
- regulators: : List of child nodes that specify the regulator
|
|
initialization data. Child nodes must be named
|
|
after their hardware counterparts: dcdc[1-4] and
|
|
ldo[1-10]. Each child nodes is defined using the
|
|
standard binding for regulators.
|
|
|
|

|
|
interrupts = <28 IRQ_TYPE_LEVEL_LOW>;
|
|
interrupt-controller;
|
|
#interrupt-cells = <2>;
|
|
gpio-controller;
|
|
#gpio-cells = <2>;
