1 * TPS65086 Power Management Integrated Circuit (PMIC) bindings
2
3 Required properties:
4  - compatible           : Should be "ti,tps65086".
5  - reg                  : I2C slave address.
6  - interrupt-parent     : Phandle to the parent interrupt controller.
7  - interrupts           : The interrupt line the device is connected to.
8  - interrupt-controller : Marks the device node as an interrupt controller.
9  - #interrupt-cells     : The number of cells to describe an IRQ, should be 2.
10                             The first cell is the IRQ number.
11                             The second cell is the flags, encoded as trigger
12                             masks from ../interrupt-controller/interrupts.txt.
13  - gpio-controller      : Marks the device node as a GPIO Controller.
14  - #gpio-cells          : Should be two.  The first cell is the pin number and
15                             the second cell is used to specify flags.
16                             See ../gpio/gpio.txt for more information.
17  - regulators:          : List of child nodes that specify the regulator
18                             initialization data. Child nodes must be named
19                             after their hardware counterparts: buck[1-6],
20                             ldoa[1-3], swa1, swb[1-2], and vtt. Each child
21                             node is defined using the standard binding for
22                             regulators and the optional regulator properties
23                             defined below.
24
25 Optional regulator properties:
26  - ti,regulator-step-size-25mv  : This is applicable for buck[1,2,6], set this
27                                     if the regulator is factory set with a 25mv
28                                     step voltage mapping.
29  - ti,regulator-decay           : This is applicable for buck[1-6], set this if
30                                     the output needs to decay, default is for
31                                     the output to slew down.

38                 interrupt-parent = <&gpio1>;
39                 interrupts = <28 IRQ_TYPE_LEVEL_LOW>;
40                 interrupt-controller;
41                 #interrupt-cells = <2>;
42                 gpio-controller;
43                 #gpio-cells = <2>;

45                 regulators {
46                         buck1 {
47                                 regulator-name = "vcc1";
48                                 regulator-min-microvolt = <1600000>;
49                                 regulator-max-microvolt = <1600000>;
50                                 regulator-boot-on;
51                                 ti,regulator-decay;
52                                 ti,regulator-step-size-25mv;
