0001 Texas Instruments TWL family
0002
0003 The TWLs are Integrated Power Management Chips.
0004 Some version might contain much more analog function like
0005 USB transceiver or Audio amplifier.
0006 These chips are connected to an i2c bus.

0009 Required properties:
0010 - compatible : Must be "ti,twl4030";
0011 For Integrated power-management/audio CODEC device used in OMAP3
0012 based boards
0013 - compatible : Must be "ti,twl6030";
0014 For Integrated power-management used in OMAP4 based boards
0015 - interrupts : This i2c device has an IRQ line connected to the main SoC
0016 - interrupt-controller : Since the twl support several interrupts internally,
0017 it is considered as an interrupt controller cascaded to the SoC one.
0018 - #interrupt-cells = <1>;
0019
0020 Optional node:
0021 - Child nodes contain in the twl. The twl family is made of several variants
0022 that support a different number of features.
0023 The children nodes will thus depend of the capability of the variant.
