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.
7
8
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>;
19- interrupt-parent : The parent interrupt controller.
20
21Optional 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.
