    1 * Texas Instruments - drv260x Haptics driver family
    2 
    3 Required properties:
    4         - compatible - One of:
    5                 "ti,drv2604" - DRV2604
    6                 "ti,drv2605" - DRV2605
    7                 "ti,drv2605l" - DRV2605L
    8         - reg -  I2C slave address
    9         - vbat-supply - Required supply regulator
   10         - mode - Power up mode of the chip (defined in include/dt-bindings/input/ti-drv260x.h)
   11                 DRV260X_LRA_MODE - Linear Resonance Actuator mode (Piezoelectric)
   12                 DRV260X_LRA_NO_CAL_MODE - This is a LRA Mode but there is no calibration
   13                                 sequence during init.  And the device is configured for real
   14                                 time playback mode (RTP mode).
   15                 DRV260X_ERM_MODE - Eccentric Rotating Mass mode (Rotary vibrator)
   16         - library-sel - These are ROM based waveforms pre-programmed into the IC.
   17                                 This should be set to set the library to use at power up.
   18                                 (defined in include/dt-bindings/input/ti-drv260x.h)
   19                 DRV260X_LIB_EMPTY - Do not use a pre-programmed library
   20                 DRV260X_ERM_LIB_A - Pre-programmed Library
   21                 DRV260X_ERM_LIB_B - Pre-programmed Library
   22                 DRV260X_ERM_LIB_C - Pre-programmed Library
   23                 DRV260X_ERM_LIB_D - Pre-programmed Library
   24                 DRV260X_ERM_LIB_E - Pre-programmed Library
   25                 DRV260X_ERM_LIB_F - Pre-programmed Library
   26                 DRV260X_LIB_LRA - Pre-programmed LRA Library
   27 
   28 Optional properties:
   29         - enable-gpio - gpio pin to enable/disable the device.
   30         - vib-rated-mv - The rated voltage of the actuator in millivolts.
   31                           If this is not set then the value will be defaulted to
   32                           3.2 v.
   33         - vib-overdrive-mv - The overdrive voltage of the actuator in millivolts.
   34                           If this is not set then the value will be defaulted to
   35                           3.2 v.
   36 Example:
   37 
   38 haptics: haptics@5a {
   39         compatible = "ti,drv2605l";
   40         reg = <0x5a>;
   41         vbat-supply = <&vbat>;
   42         enable-gpio = <&gpio1 28 GPIO_ACTIVE_HIGH>;
   43         mode = <DRV260X_LRA_MODE>;
   44         library-sel = <DRV260X_LIB_LRA>;
   45         vib-rated-mv = <3200>;
   46         vib-overdrive-mv = <3200>;
   47 }
