Pull input subsystem fixes from Dmitry Torokhov:
 "A couple of driver/build fixups and also redone quirk for Synaptics
  touchpads on Lenovo boxes (now using PNP IDs instead of DMI data to
  limit number of quirks)"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: synaptics - change min/max quirk table to pnp-id matching
  Input: synaptics - add a matches_pnp_id helper function
  Input: synaptics - T540p - unify with other LEN0034 models
  Input: synaptics - add min/max quirk for the ThinkPad W540
  Input: ambakmi - request a shared interrupt for AMBA KMI devices
  Input: pxa27x-keypad - fix generating scancode
  Input: atmel-wm97xx - only build for AVR32
  Input: fix ps2/serio module dependency

Building this driver on ARM/at91 always gives us this error message:

drivers/input/touchscreen/atmel-wm97xx.c:63:2: error: #error Unknown CPU, this driver only supports AT32AP700X CPUs.

Clearly this configuration is not meant to work, so let's just prevent
it in Kconfig. If we ever want to use it on another platform, we should
also pass proper resources for GPIO, IRQ and memory, which are hardcoded
to AT32AP700X at the moment.

Pull input updates from Dmitry Torokhov:
 "The main change is that we now publish "firmware ID" for the serio
  devices to help userspace figure out the kind of touchpads it is
  dealing with: i8042 will export PS/2 port's PNP IDs as firmware IDs.

  You will also get more quirks for Synaptics touchpads in various
  Lenovo laptops, a change to elantech driver to recognize even more
  models, and fixups to wacom and couple other drivers"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: elantech - add support for newer elantech touchpads
  Input: soc_button_array - fix a crash during rmmod
  Input: synaptics - add min/max quirk for ThinkPad T431s, L440, L540, S1 Yoga and X1
  Input: synaptics - report INPUT_PROP_TOPBUTTONPAD property
  Input: Add INPUT_PROP_TOPBUTTONPAD device property
  Input: i8042 - add firmware_id support
  Input: serio - add firmware_id sysfs attribute
  Input: wacom - handle 1024 pressure levels in wacom_tpc_pen
  Input: wacom - references to 'wacom->data' should use 'unsigned char*'
  Input: wacom - override 'pressure_max' with value from HID_USAGE_PRESSURE
  Input: wacom - use full 32-bit HID Usage value in switch statement
  Input: wacom - missed the last bit of expresskey for DTU-1031
  Input: ads7846 - fix device usage within attribute show
  Input: da9055_onkey - remove use of regmap_irq_get_virq()

With commit e585c40ba (Input: ads7846 - convert to
hwmon_device_register_with_groups()) the device passed to the attribute's
show function isn't the spi device as before.
So fixup the passed device to ads7846_read12_ser.

There is a new firmware version for the EDT-FT5x06 chip.
Add support for detecting the firmware version and handle the
differences appropriately.

The chip may report invalid coordinates on touchdown events, so don't
report the initial touchdown event.

The FT5x06 datasheet specifies a minimum reset width of 5ms and a
delay between deassertion of reset and start of reporting of 300ms.
Adjust the delays to conform to the datasheet.

With the original delays I sometimes experienced communication
timeouts when initializing the controller.
