1 Texas Instruments TWL family
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.
10 - compatible : Must be "ti,twl4030";
11 For Integrated power-management/audio CODEC device used in OMAP3
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>;
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.
