1Texas Instruments TWL family (twl4030) reset and power management module
2
3The power management module inside the TWL family provides several facilities
4to control the power resources, including power scripts. For now, the
5binding only supports the complete shutdown of the system after poweroff.
6
7Required properties:
8- compatible : must be one of the following
9	"ti,twl4030-power"
10	"ti,twl4030-power-reset"
11	"ti,twl4030-power-idle"
12	"ti,twl4030-power-idle-osc-off"
13
14The use of ti,twl4030-power-reset is recommended at least on
153530 that needs a special configuration for warm reset to work.
16
17When using ti,twl4030-power-idle, the TI recommended configuration
18for idle modes is loaded to the tlw4030 PMIC.
19
20When using ti,twl4030-power-idle-osc-off, the TI recommended
21configuration is used with the external oscillator being shut
22down during off-idle. Note that this does not work on all boards
23depending on how the external oscillator is wired.
24
25Optional properties:
26
27- ti,system-power-controller: This indicates that TWL4030 is the
28  power supply master of the system. With this flag, the chip will
29  initiate an ACTIVE-to-OFF or SLEEP-to-OFF transition when the
30  system poweroffs.
31
32- ti,use_poweroff: Deprecated name for ti,system-power-controller
33
34Example:
35&i2c1 {
36	clock-frequency = <2600000>;
37
38	twl: twl@48 {
39		reg = <0x48>;
40		interrupts = <7>; /* SYS_NIRQ cascaded to intc */
41		interrupt-parent = <&intc>;
42
43		twl_power: power {
44			compatible = "ti,twl4030-power";
45			ti,use_poweroff;
46		};
47	};
48};
