Input: twl6040-vibra - update for device tree support
The twl6040 DT support implementation has been changed from the originally planned. None of the child devices going to have compatible_of property which means that the child devices of twl6040 will be created as traditional MFD devices. The mfd core driver will decide (based on the DT blob) to create a device for the twl6040-vibra or not. If the DT blob has 'vibra' section the device will be created without pdata. In this case the vibra driver will reach up to the parent node to get the needed properties. With DT booted kernel we no longer be able to link the regulators to the vibra driver, they can be only linked to the MFD device (probed via DT). From the vibra driver we ned to use pdev->dev.parent to get the regulators. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

-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
