Pull input layer updates from Dmitry Torokhov:

 - evdev interface has been adjusted to extend the life of timestamps on
   32 bit systems to the year of 2108

 - Synaptics RMI4 driver's PS/2 guest handling ha beed updated to
   improve chances of detecting trackpoints on the pass-through port

 - mms114 touchcsreen controller driver has been updated to support
   generic device properties and work with mms152 cntrollers

 - Goodix driver now supports generic touchscreen properties

 - couple of drivers for AVR32 architecture are gone as the architecture
   support has been removed from the kernel

 - gpio-tilt driver has been removed as there are no mainline users and
   the driver itself is using legacy APIs and relies on platform data

 - MODULE_LINECSE/MODULE_VERSION cleanups

Pull driver core updates from Greg KH:
 "Here is the set of "big" driver core patches for 4.16-rc1.

  The majority of the work here is in the firmware subsystem, with
  reworks to try to attempt to make the code easier to handle in the
  long run, but no functional change. There's also some tree-wide sysfs
  attribute fixups with lots of acks from the various subsystem
  maintainers, as well as a handful of other normal fixes and changes.

  And finally, some license cleanups for the driver core and sysfs code.

  All have been in linux-next for a while with no reported issues"

Merge branch 'next' into for-linus

Prepare input updates for 4.16 merge window.

Input: goodix - use generic touchscreen_properties

2018-01-31T22:44:40+00:00

Use touchscreen_properties structure instead of implementing all
properties by our own. It allows us to reuse generic code for parsing
device-tree properties (which was implemented manually in the driver for
now). Additionally, it allows us to report events using generic
touchscreen_report_pos(), which automatically handles inverted and
swapped axes.

This fixes the issue with the custom code incorrectly handling case where
ts->inverted_x and ts->swapped_x_y were true, but ts->inverted_y was
false. Assuming we have 720x1280 touch panel, ts->abs_x_max == 1279 and
ts->abs_y_max == 719 (because we inverted that in goodix_read_config()).
Now let's assume that we received event from (0:0) position (in touch
panel original coordinates). In function goodix_ts_report_touch() we
calculate input_x as 1279, but after swapping input_y takes that value
(which is more that maximum 719 value reported during initialization).

Note that since touchscreen coordinates are 0-indexed, we now report
touchscreen range as (0:size-1).

Developed and tested on custom DT-based device with gt1151 touch
panel.

Input: mms114 - replace mdelay with msleep

2018-01-30T18:08:12+00:00

200 milliseconds is a very long time to keep the CPU busy looping.
Use msleep instead.

Input: mms114 - add support for mms152

2018-01-26T19:27:45+00:00

MMS152 has no configuration registers, but the packet format used in
interrupts is identical to mms114.

Input: mms114 - drop platform data and use generic APIs

2018-01-26T19:27:23+00:00

The MMS114 platform data has no in-tree users, so drop it.

Switch to using the standard touchscreen properties via
touchscreen_parse_properties(), and move the old DT parsing code
to use device_property_*() APIs.

Finally, use touchscreen_report_pos to report x/y coordinates
and drop the custom x/y inversion code.

Input: mms114 - mark as direct input device

2018-01-26T19:27:18+00:00

mms14 is a touchscreen and thus a direct input device; let's mark it
as such. This also allows us to drop some initialization code as
input_init_mt_slots() will do that for us.

Also add error handling for input_mt_init_slots().
