[Patch v3] input: drv260x: Add TI drv260x haptics driver
Add the TI drv260x haptics/vibrator driver.
This device uses the input force feedback
to produce a wave form to driver an
ERM or LRA actuator device.
The initial driver supports the devices
real time playback mode. But the device
has additional wave patterns in ROM.
This functionality will be added in
future patchsets.

Re: [Patch v3] input: drv260x: Add TI drv260x haptics driver
Dmitry
Thanks for the review.

Add the TI drv260x haptics/vibrator driver.
This device uses the input force feedback
to produce a wave form to driver an
ERM or LRA actuator device.
The initial driver supports the devices
real time playback mode. But the device
has additional wave patterns in ROM.
This functionality will be added in
future patchsets.

+Texas Instruments - drv260x Haptics driver family
+
+The drv260x family serial control bus communicates through I2C protocols
+
+Required properties:
+- compatible - One of:
+ti,drv2604 - DRV2604
+ti,drv2605 - DRV2605
+ti,drv2605l - DRV2605L
+- reg - I2C slave address
+- supply- Required supply regulators are:
+vbat - battery voltage
+- 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_A - Pre-programmed Library
+DRV260X_LIB_B - Pre-programmed Library
+DRV260X_LIB_C - Pre-programmed Library
+DRV260X_LIB_D - Pre-programmed Library
+DRV260X_LIB_E - Pre-programmed Library
+DRV260X_LIB_F - Pre-programmed Library
+
+Optional properties:
+- enable-gpio - gpio pin to enable/disable the device.
+- vib_rated_voltage - 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_voltage - The overdrive voltage of the actuator in
millivolts.
+ If this is not set then the value will be defaulted to
+ 3.2 v.
+Example:
+
+drv2605l: drv2605l@5a {
+compatible = ti,drv2605l;
+reg = 0x5a;
+enable-gpio = gpio1 28 GPIO_ACTIVE_HIGH;
+mode = DRV260X_LRA_MODE;
+library-sel = DRV260X_LIB_SEL_DEFAULT;
+vib-rated-voltage = 3200;
+vib-overdriver-voltage = 3200;
