* 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-overdriver-mv = <3200>;

}

Texas Instruments Palmas family power button module



This module is part of the Palmas family of PMICs. For more details

about the whole chip see:

Documentation/devicetree/bindings/mfd/palmas.txt.



This module provides a simple power button event via an Interrupt.



Required properties:

- compatible: should be one of the following

   - "ti,palmas-pwrbutton": For Palmas compatible power on button

- interrupt-parent: Parent interrupt device, must be handle of palmas node.

- interrupts: Interrupt number of power button submodule on device.



Optional Properties:



- ti,palmas-long-press-seconds: Duration in seconds which the power

  button should be kept pressed for Palmas to power off automatically.

  NOTE: This depends on OTP support and POWERHOLD signal configuration

  on platform. Valid values are 6, 8, 10 and 12.

- ti,palmas-pwron-debounce-milli-seconds: Duration in milliseconds

  which the power button should be kept pressed for Palmas to register

  a press for debouncing purposes. NOTE: This depends on specific

  Palmas variation capability. Valid values are 15, 100, 500 and 1000.



Example:



&palmas {

	palmas_pwr_button: pwrbutton {

		compatible = "ti,palmas-pwrbutton";

		interrupt-parent = <&tps659038>;

		interrupts = <1 IRQ_TYPE_EDGE_FALLING>;

		ti,palmas-long-press-seconds = <12>;

		ti,palmas-pwron-debounce-milli-seconds = <15>;

	};

};
