Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input 

Pull more input updates from Dmitry Torokhov:
 "A second round of updates for the input subsystem:

   - a new driver for PWM-controlled vibrators

   - ucb1400 touchscreen driver had completely busted suspend/resume
     handling

   - we now handle "home" button found on some devices with Goodix
     touchscreens

   - assorted other fixups"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: i8042 - add Gigabyte P57 to the keyboard reset table
  Input: xpad - validate USB endpoint type during probe
  Input: ucb1400_ts - fix suspend and resume handling
  Input: edt-ft5x06 - fix access to non-existing register
  Input: elantech - make arrays debounce_packet static, reduces object code size
  Input: surface3_spi - make const array header static, reduces object code size
  Input: goodix - add support for capacitive home button
  Input: add a driver for PWM controllable vibrators
  Input: adi - make array seq static, reduces object code size

* PWM vibrator device tree bindings



Registers a PWM device as vibrator. It is expected, that the vibrator's

strength increases based on the duty cycle of the enable PWM channel

(100% duty cycle meaning strongest vibration, 0% meaning no vibration).



The binding supports an optional direction PWM channel, that can be

driven at fixed duty cycle. If available this is can be used to increase

the vibration effect of some devices.



Required properties:

- compatible: should contain "pwm-vibrator"

- pwm-names: Should contain "enable" and optionally "direction"

- pwms: Should contain a PWM handle for each entry in pwm-names



Optional properties:

- vcc-supply: Phandle for the regulator supplying power

- direction-duty-cycle-ns: Duty cycle of the direction PWM channel in

                           nanoseconds, defaults to 50% of the channel's

			   period.



Example from Motorola Droid 4:



&omap4_pmx_core {

	vibrator_direction_pin: pinmux_vibrator_direction_pin {

		pinctrl-single,pins = <

		OMAP4_IOPAD(0x1ce, PIN_OUTPUT | MUX_MODE1) /* dmtimer8_pwm_evt (gpio_27) */

		>;

	};



	vibrator_enable_pin: pinmux_vibrator_enable_pin {

		pinctrl-single,pins = <

		OMAP4_IOPAD(0X1d0, PIN_OUTPUT | MUX_MODE1) /* dmtimer9_pwm_evt (gpio_28) */

		>;

	};

};



/ {

	pwm8: dmtimer-pwm {

		pinctrl-names = "default";

		pinctrl-0 = <&vibrator_direction_pin>;



		compatible = "ti,omap-dmtimer-pwm";

		#pwm-cells = <3>;

		ti,timers = <&timer8>;

		ti,clock-source = <0x01>;

	};



	pwm9: dmtimer-pwm {

		pinctrl-names = "default";

		pinctrl-0 = <&vibrator_enable_pin>;



		compatible = "ti,omap-dmtimer-pwm";

		#pwm-cells = <3>;

		ti,timers = <&timer9>;

		ti,clock-source = <0x01>;

	};



	vibrator {

		compatible = "pwm-vibrator";

		pwms = <&pwm8 0 1000000000 0>,

		       <&pwm9 0 1000000000 0>;

		pwm-names = "enable", "direction";

		direction-duty-cycle-ns = <1000000000>;

	};

};
