The driver looks for "vib-overdrive-mv" property, while in documentation we have "vib-overdriver-mv". Fix the doc. Cc: Francesco Diotalevi <francesco.diotalevi@iit.it> Signed-off-by: Andrea Merello <andrea.merello@gmail.com> Signed-off-by: Rob Herring <robh@kernel.org>

* Texas Instruments - drv260x Haptics driver family
|
|
|
|
Required properties:
|
|
- compatible - One of:
|
|
"ti,drv2604" - DRV2604
|
|
"ti,drv2605" - DRV2605
|
|
"ti,drv2605l" - DRV2605L
|
|
- reg - I2C slave address
|
|
- vbat-supply - Required supply regulator
|
|
- 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_EMPTY - Do not use a pre-programmed library
|
|
DRV260X_ERM_LIB_A - Pre-programmed Library
|
|
DRV260X_ERM_LIB_B - Pre-programmed Library
|
|
DRV260X_ERM_LIB_C - Pre-programmed Library
|
|
DRV260X_ERM_LIB_D - Pre-programmed Library
|
|
DRV260X_ERM_LIB_E - Pre-programmed Library
|
|
DRV260X_ERM_LIB_F - Pre-programmed Library
|
|
DRV260X_LIB_LRA - Pre-programmed LRA Library
|
|
|
|
Optional properties:
|
|
- enable-gpio - gpio pin to enable/disable the device.
|
|
- vib-rated-mv - 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-mv - The overdrive voltage of the actuator in millivolts.
|
|
If this is not set then the value will be defaulted to
|
|
3.2 v.
|
|
Example:
|
|
|
|
haptics: haptics@5a {
|
|
compatible = "ti,drv2605l";
|
|
reg = <0x5a>;
|
|
vbat-supply = <&vbat>;
|
|
enable-gpio = <&gpio1 28 GPIO_ACTIVE_HIGH>;
|
|
mode = <DRV260X_LRA_MODE>;
|
|
library-sel = <DRV260X_LIB_LRA>;
|
|
vib-rated-mv = <3200>;
|
|
vib-overdrive-mv = <3200>;
|
|
}
