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