1	Texas Instruments TWL family
2	
3	The TWLs are Integrated Power Management Chips.
4	Some version might contain much more analog function like
5	USB transceiver or Audio amplifier.
6	These chips are connected to an i2c bus.
7	
8	
9	Required properties:
10	- compatible : Must be "ti,twl4030";
11	  For Integrated power-management/audio CODEC device used in OMAP3
12	  based boards
13	- compatible : Must be "ti,twl6030";
14	  For Integrated power-management used in OMAP4 based boards
15	- interrupts : This i2c device has an IRQ line connected to the main SoC
16	- interrupt-controller : Since the twl support several interrupts internally,
17	  it is considered as an interrupt controller cascaded to the SoC one.
18	- #interrupt-cells = <1>;
19	- interrupt-parent : The parent interrupt controller.
20	
21	Optional node:
22	- Child nodes contain in the twl. The twl family is made of several variants
23	  that support a different number of features.
24	  The children nodes will thus depend of the capability of the variant.
25

27	Example:
28	/*
29	 * Integrated Power Management Chip
30	 * http://www.ti.com/lit/ds/symlink/twl6030.pdf
31	 */
32	twl@48 {
33	    compatible = "ti,twl6030";
34	    reg = <0x48>;
35	    interrupts = <39>; /* IRQ_SYS_1N cascaded to gic */
36	    interrupt-controller;
37	    #interrupt-cells = <1>;
38	    interrupt-parent = <&gic>;
39	    #address-cells = <1>;
40	    #size-cells = <0>;
41	
42	    twl_rtc {
43	        compatible = "ti,twl_rtc";
44	        interrupts = <11>;
45	        reg = <0>;
46	    };
47	};
