Enable DT based probing of the vibra driver.
Example of dts section to load the twl6040-vibra driver:
twl6040: twl6040@4b {
...
twl6040_vibra: twl6040@1 {
compatible = "ti,twl6040-vibra";
interrupts = <4>;
vddvibl-supply = <&vbat>;
vddvibr-supply = <&vbat>;
vibldrv_res = <8>;
vibrdrv_res = <3>;
viblmotor_res = <10>;
vibrmotor_res = <10>;
};
};

Vibra driver for the twl6040 family
|
|
|
|
The vibra driver is a child of the twl6040 MFD dirver.
|
|
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
|
|
|
