+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;

[PATCH v5] 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.

+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.

+Optional properties:

[PATCH v5] 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.

v5 - Move register defines to c file and rm header file, error check
init in probe, fixed identation, remove empty labels in probe
and just return on fail and removed the remove callback and function.
Did not factor out the suspend into a stop function. -
https://patchwork.kernel.org/patch/4649631/
v4 - Convert regulator to devm, added error checking where required,
updated bindings doc, moved dt parsing to separate call and made platform
data the first data point, moved vibrator enable and mode programming from
play entry to worker thread, added user check and input mutex in suspend/resume
calls, moved platform data to individual file and into include platform-data
directory,
removed file names from file headers -
https://patchwork.kernel.org/patch/4642221/
v3 - Updated binding doc, changed to memless device, updated input alloc to
devm, removed mutex locking, add sanity checks for mode and library -
https://patchwork.kernel.org/patch/4635421/
v2 - Fixed binding doc and patch headline -
https://patchwork.kernel.org/patch/4619641/
