- * Texas Instruments - drv2624 Haptics driver
- Required properties:
- - compatible - "ti,drv2624" - DRV2624
- - reg - I2C slave address
- - ti,reset-gpio - GPIO to reset the device
- Optional properties:
- - ti,irq-gpio - GPIO to receive the interrupt
- - ti,voltage-comp - Voltage compensation for any resistive losses in the
- driver IC.
- - ti,ol-lra-frequency - LRA frequency for open-loop mode
- - ti,bemf-factor - Sets the feedback gain for closed-loop operation
- - ti,bemf-gain - Sets the analog gain of the back-EMF amplifier
- - ti,blanking-time - Time waiting for BEMF to settle. Before ADC
- sampling
- - ti,idiss-time - Sime waiting for inductor current to discharge
- - ti,zc-det-time - Zero crossing detection time
- - ti,lra-wave-shape - Selects which shape to use for driving the LRA
- when in open loop mode. 0 - Square Wave, 1 - Sine Wave.
- - ti,waveform-interval - Sets the internal memory playback interval to
- either 5 ms or 1 ms. 0 - 5 ms, 1 - 1 ms.
- Example:
- drv2624: drv2624@5a {
- compatible = "ti,drv2624";
- reg = <0x5a>;
- ti,reset-gpio = <&tlmm 95 0>;
- };
