Input: tl6040-vibra - Device Tree support
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>;
};
};
