+* 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>;

+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>;
+	};
