Subject: [PATCH 00/10] Add binding from PS/2 to SMBus for Synaptics and Elan

Hi,

Well, this is the last series which enables RMI4 over SMBus for the Thinkpad
t*40, t*50, t*60 series. Few comments on the patches:

patches 1 to 3 allows the re-routing of the trackstick buttons from the touchpad
  to the trackstick
patch 4 to 7 allow rmi_smbus to actually control the PS/2 node to not resume and
  mess up the configuration after a resume
patch 8 was originally sent as a RMI4 specific driver, but I came to realise
  that Elan could also benefit from the same driver
patch 9 has already been sent once, but there was no clear way of enabling the
  trackstick, so it was not merged
patch 10 allows the elantech driver to create an instance of elan_i2c and
  forwards the trackstick information from PS/2

Note that patch 10 has only been tested on a machine without a functional
elan_i2c touchpad, so only the binding has been tested.

This series requires the Host Notify flag patch from Dmitry:

Cheers,
Benjamin

  Input: serio - store the pt_buttons in the struct serio directly
  Input: synaptics-rmi4 - Add rmi_find_function()
  Input: synaptics-rmi4 - f30/f03: Forward mechanical buttons on
    buttonpads to PS/2 guest
  Input: psmouse - allow to deactivate a driver from the serio handle
  Input: synaptics - allocate a Synaptics Intertouch device
  Input: synaptics-rmi4 - smbus: call psmouse_deactivate before
    binding/resume
  Input: synaptics-rmi4 - smbus: on resume, try 3 times if init fails
  Input: add a PS/2 to SMBus platform module
  Input: elan_i2c - add trackstick report
  Input: elantech - automatically bind an SMBus device when acceptable
