DRV2604 Haptic Driver

The DRV2604 device is designed to provide extremely flexible haptic control of ERM and LRA actuators over a shared I2C compatible bus. This control relieves the host processor from ever generating pulse-width modulated (PWM) drive signals, saving both costly timer interrupts and SDA SCL EN IN/TRIG .
