1Texas Instruments TWL family
2
3The TWLs are Integrated Power Management Chips.
4Some version might contain much more analog function like
5USB transceiver or Audio amplifier.
6These chips are connected to an i2c bus.

9Required 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>;

20Optional node:
21- Child nodes contain in the twl. The twl family is made of several variants
22  that support a different number of features.
23  The children nodes will thus depend of the capability of the variant.
