   1* Texas Instruments - drv260x Haptics driver family
   2
   3Required 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
  28Optional 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.
  36Example:
  37
  38haptics: 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>;
