Title:
  regression: Cypress touchpad driver (cyapa) ignores events after bieng
  idle for 2 seconds

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Driver update in Kernel 4.2 causes severe usability issues with
  Cypress touchpad (cyapa) used on Acer C7x0 chromebooks.

  The driver in question is ignoring events during entering/leaving idle
  status which from user standpoint seems like touchpad is not reacting
  to actions performed after touchpad is not used for more then 2
  seconds.

  The bug was partially fixed in 4.3 and additional fix was pushed to
  upcoming 4.5.

  After direct communication with driver maintainer, we came up with 2 patches fixing the problem.
  Since 4.2 is EOL now, the patches cannot be pushed into upstream therefor are posted here.

  First patch is a backport of driver from 4.3 to 4.2 and the second
  patch is additional fix that should be applied on 4.3/4.4.

  Tested:
  - 4.2.0-23-generic #28~14.04.1-Ubuntu on Acer C710
  - 4.4 mainline on Acer C720p
