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

Pull input updates from Dmitry Torokhov:

 - support for inhibiting input devices at request from userspace. If a
   device implements open/close methods, it can also put device into low
   power state. This is needed, for example, to disable keyboard and
   touchpad on convertibles when they are transitioned into tablet mode

 - now that ordinary input devices can be configured for polling mode,
   dedicated input polling device implementation has been removed

 - GTCO tablet driver has been removed, as it used problematic custom
   HID parser, devices are EOL, and there is no interest from the
   manufacturer

 - a new driver for Dialog DA7280 haptic chips has been introduced

 - a new driver for power button on Dell Wyse 3020

 - support for eKTF2132 in ektf2127 driver

 - support for SC2721 and SC2730 in sc27xx-vibra driver

 - enhancements for Atmel touchscreens, AD7846 touchscreens, Elan
   touchpads, ADP5589, ST1232 touchscreen, TM2 touchkey drivers

 - fixes and cleanups to allow clean builds with W=1

atmel,mXT224
- reg: The I2C address of the device
- interrupts: The sink for the touchpad's IRQ output
See ../interrupt-controller/interrupts.txt
Optional properties for main touchpad device:
- linux,gpio-keymap: When enabled, the SPT_GPIOPWN_T19 object sends messages
on GPIO bit changes. An array of up to 8 entries can be provided
indicating the Linux keycode mapped to each bit of the status byte,
starting at the LSB. Linux keycodes are defined in
<dt-bindings/input/input.h>.
Note: the numbering of the GPIOs and the bit they start at varies between
maXTouch devices. You must either refer to the documentation, or
experiment to determine which bit corresponds to which input. Use
KEY_RESERVED for unused padding values.
- reset-gpios: GPIO specifier for the touchscreen's reset pin (active low)
Example:
touch@4b {

The open() callback should return a 0 in case of success or any nonzero value
in case of failure. The close() callback (which is void) must always succeed.
Inhibiting input devices
~~~~~~~~~~~~~~~~~~~~~~~~
Inhibiting a device means ignoring input events from it. As such it is about
maintaining relationships with input handlers - either already existing
relationships, or relationships to be established while the device is in
inhibited state.
If a device is inhibited, no input handler will receive events from it.
The fact that nobody wants events from the device is exploited further, by
calling device's close() (if there are users) and open() (if there are users) on
inhibit and uninhibit operations, respectively. Indeed, the meaning of close()
is to stop providing events to the input core and that of open() is to start
providing events to the input core.
Calling the device's close() method on inhibit (if there are users) allows the
driver to save power. Either by directly powering down the device or by
releasing the runtime-pm reference it got in open() when the driver is using
runtime-pm.
Inhibiting and uninhibiting are orthogonal to opening and closing the device by
input handlers. Userspace might want to inhibit a device in anticipation before
any handler is positively matched against it.
Inhibiting and uninhibiting are orthogonal to device's being a wakeup source,
too. Being a wakeup source plays a role when the system is sleeping, not when
the system is operating. How drivers should program their interaction between
inhibiting, sleeping and being a wakeup source is driver-specific.
Taking the analogy with the network devices - bringing a network interface down
doesn't mean that it should be impossible be wake the system up on LAN through
this interface. So, there may be input drivers which should be considered wakeup
sources even when inhibited. Actually, in many I2C input devices their interrupt
is declared a wakeup interrupt and its handling happens in driver's core, which
is not aware of input-specific inhibit (nor should it be). Composite devices
containing several interfaces can be inhibited on a per-interface basis and e.g.
inhibiting one interface shouldn't affect the device's capability of being a
wakeup source.
If a device is to be considered a wakeup source while inhibited, special care
must be taken when programming its suspend(), as it might need to call device's
open(). Depending on what close() means for the device in question, not
opening() it before going to sleep might make it impossible to provide any
wakeup events. The device is going to sleep anyway.
