Commit 718749d5 authored by Linus Torvalds's avatar Linus Torvalds

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

Pull input updates from Dmitry Torokhov:
 "The first round of updates for the input subsystem.

  A few new drivers (power button handler for AXP20x PMIC, tps65218
  power button driver, sun4i keys driver, regulator haptic driver, NI
  Ettus Research USRP E3x0 button, Alwinner A10/A20 PS/2 controller).

  Updates to Synaptics and ALPS touchpad drivers (with more to come
  later), brand new Focaltech PS/2 support, update to Cypress driver to
  handle Gen5 (in addition to Gen3) devices, and number of other fixups
  to various drivers as well as input core"

National Instruments Ettus Research USRP E3x0 button driver
This module is part of the NI Ettus Research USRP E3x0 SDR.
This module provides a simple power button event via two interrupts.
Required properties:
- compatible: should be one of the following
- "ettus,e3x0-button": For devices such as the NI Ettus Research USRP E3x0
- interrupt-parent:
- a phandle to the interrupt controller that it is attached to.
- interrupts: should be one of the following
- <0 30 1>, <0 31 1>: For devices such as the NI Ettus Research USRP E3x0
- interrupt-names: should be one of the following
- "press", "release": For devices such as the NI Ettus Research USRP E3x0
Note: Interrupt numbers might vary depending on the FPGA configuration.
Example:
button {
compatible = "ettus,e3x0-button";
interrupt-parent = <&intc>;
interrupts = <0 30 1>, <0 31 1>;
interrupt-names = "press", "release";
}
* Regulator Haptic Device Tree Bindings
Required Properties:
- compatible : Should be "regulator-haptic"

[The unit of the voltage is a micro]
- min-microvolt : The minimum voltage value supplied to the haptic motor.
[The unit of the voltage is a micro]
Example:
haptics {
compatible = "regulator-haptic";
haptic-supply = <&motor_regulator>;
max-microvolt = <2700000>;
min-microvolt = <1100000>;

charge step, so this does in fact function as a
hardware knob for adjusting the amount of "settling
