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

Browse source 
Pull input subsystem updates from Dmitry Torokhov:
 "- we finally merged driver for USB version of Synaptics touchpads
    (I guess most commonly found in IBM/Lenovo keyboard/touchpad combo);

   - a bunch of new drivers for embedded platforms (Cypress
     touchscreens, DA9052 OnKey, MAX8997-haptic, Ilitek ILI210x
     touchscreens, TI touchscreen);

   - input core allows clients to specify desired clock source for
     timestamps on input events (EVIOCSCLOCKID ioctl);

   - input core allows querying state of all MT slots for given event
     code via EVIOCGMTSLOTS ioctl;

   - various driver fixes and improvements."

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (45 commits)
  Input: ili210x - add support for Ilitek ILI210x based touchscreens

A simple common binding for matrix-connected key boards. Currently targeted at
defining the keys in the scope of linux key codes since that is a stable and
standardized interface at this time.
Required properties:
- linux,keymap: an array of packed 1-cell entries containing the equivalent
of row, column and linux key-code. The 32-bit big endian cell is packed
as:
row << 24 | column << 16 | key-code
Optional properties:
Some users of this binding might choose to specify secondary keymaps for
cases where there is a modifier key such as a Fn key. Proposed names
for said properties are "linux,fn-keymap" or with another descriptive
word for the modifier other from "Fn".
Example:
linux,keymap = < 0x00030012
0x0102003a >;

Required properties:
- compatible: "nvidia,tegra20-kbc"
Optional properties:
- debounce-delay: delay in milliseconds per row scan for debouncing
- repeat-delay: delay in milliseconds before repeat starts
- ghost-filter: enable ghost filtering for this device
- wakeup-source: configure keyboard as a wakeup source for suspend/resume
Optional properties, in addition to those specified by the shared
matrix-keyboard bindings:
- linux,fn-keymap: a second keymap, same specification as the
matrix-keyboard-controller spec but to be used when the KEY_FN modifier
key is pressed.
- nvidia,debounce-delay-ms: delay in milliseconds per row scan for debouncing
- nvidia,repeat-delay-ms: delay in milliseconds before repeat starts
- nvidia,ghost-filter: enable ghost filtering for this device
- nvidia,wakeup-source: configure keyboard as a wakeup source for suspend/resume
Example:
keyboard: keyboard {
compatible = "nvidia,tegra20-kbc";
reg = <0x7000e200 0x100>;
ghost-filter;
nvidia,ghost-filter;
};
