| * Texas Instruments - drv260x Haptics driver family |
| |
| Required properties: |
| - compatible - One of: |
| "ti,drv2604" - DRV2604 |
| "ti,drv2605" - DRV2605 |
| "ti,drv2605l" - DRV2605L |
| - reg - I2C slave address |
| - vbat-supply - Required supply regulator |
| - mode - Power up mode of the chip (defined in include/dt-bindings/input/ti-drv260x.h) |
| DRV260X_LRA_MODE - Linear Resonance Actuator mode (Piezoelectric) |
| DRV260X_LRA_NO_CAL_MODE - This is a LRA Mode but there is no calibration |
| sequence during init. And the device is configured for real |
| time playback mode (RTP mode). |
| DRV260X_ERM_MODE - Eccentric Rotating Mass mode (Rotary vibrator) |
| - library-sel - These are ROM based waveforms pre-programmed into the IC. |
| This should be set to set the library to use at power up. |
| (defined in include/dt-bindings/input/ti-drv260x.h) |
| DRV260X_LIB_EMPTY - Do not use a pre-programmed library |
| DRV260X_ERM_LIB_A - Pre-programmed Library |
| DRV260X_ERM_LIB_B - Pre-programmed Library |
| DRV260X_ERM_LIB_C - Pre-programmed Library |
| DRV260X_ERM_LIB_D - Pre-programmed Library |
| DRV260X_ERM_LIB_E - Pre-programmed Library |
| DRV260X_ERM_LIB_F - Pre-programmed Library |
| DRV260X_LIB_LRA - Pre-programmed LRA Library |
| |
| Optional properties: |
| - enable-gpio - gpio pin to enable/disable the device. |
| - vib-rated-mv - The rated voltage of the actuator in millivolts. |
| If this is not set then the value will be defaulted to |
| 3.2 v. |
| - vib-overdrive-mv - The overdrive voltage of the actuator in millivolts. |
| If this is not set then the value will be defaulted to |
| 3.2 v. |
| Example: |
| |
| haptics: haptics@5a { |
| compatible = "ti,drv2605l"; |
| reg = <0x5a>; |
| vbat-supply = <&vbat>; |
| enable-gpio = <&gpio1 28 GPIO_ACTIVE_HIGH>; |
| mode = <DRV260X_LRA_MODE>; |
| library-sel = <DRV260X_LIB_LRA>; |
| vib-rated-mv = <3200>; |
| vib-overdriver-mv = <3200>; |
| } |
