   1 * TPS65086 Power Management Integrated Circuit (PMIC) bindings
   2
   3 Required properties:
   4  - compatible           : Should be "ti,tps65086".
   5  - reg                  : I2C slave address.
   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: buck[1-6],
  19                             ldoa[1-3], swa1, swb[1-2], and vtt. Each child
  20                             node is defined using the standard binding for
  21                             regulators and the optional regulator properties
  22                             defined below.
  23
  24 Optional regulator properties:
  25  - ti,regulator-step-size-25mv  : This is applicable for buck[1-6], set this
  26                                     if the regulator is factory set with a 25mv
  27                                     step voltage mapping.
  28  - ti,regulator-decay           : This is applicable for buck[1-6], set this if
  29                                     the output needs to decay, default is for
  30                                     the output to slew down.

  35                 compatible = "ti,tps65086";

  38                 interrupts = <28 IRQ_TYPE_LEVEL_LOW>;
  39                 interrupt-controller;
  40                 #interrupt-cells = <2>;
  41                 gpio-controller;
  42                 #gpio-cells = <2>;
