Documentation/devicetree/bindings/mfd/twl6040.txt

Required properties:
- compatible : Must be "ti,twl6040-vibra";
- interrupts: 4, Vibra overcurrent interrupt
- vddvibl-supply: Regulator supplying the left vibra motor
- vddvibr-supply: Regulator supplying the right vibra motor
- vibldrv_res: Board specific left driver resistance
- vibrdrv_res: Board specific right driver resistance
- viblmotor_res: Board specific left motor resistance
- vibrmotor_res: Board specific right motor resistance

Optional properties:
- vddvibl_uV: If the vddvibl default voltage need to be changed
- vddvibr_uV: If the vddvibr default voltage need to be changed
