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>; 47} 48 49For more product information please see the link below: 50http://www.ti.com/product/drv2605 51
