Subject: [PATCH v2] dt-bindings: input: Convert ti,drv260x to DT schema
Convert the drv260x haptics binding to DT schema format.
The only notable change from .txt format is that vbat-supply is not
actually required, so don't make it a required property.
Signed-off-by: Luca Weiss <luca@...tu.xyz>

@Andrew Davis: You maintain some other TI bindings, would you be willing
to also maintain this one? It was originally written by Dan Murphy but
apparently Dan no longer works for TI.
Changes since v1:
* add $ref to types as suggested by Rob
* change maintainer

-* 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>;
