This driver adds support for slidebars found on some Lenovo IdeaPad
laptops (the slidebars work with SlideNav/Desktop Navigator under
Windows).

Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=16004

Registers 'IdeaPad Slidebar' input device and
/sys/devices/platform/ideapad_slidebar/slidebar_mode
for switching slidebar's modes.

Now works on:
IdeaPad Y550, Y550P.

May work on (testing and adding new models is needed):
Ideapad Y560, Y460, Y450, Y650,
and, probably, some others.

Remove unneeded error handling on the result of a call to
platform_get_resource when the value is passed to devm_ioremap_resource.

Move the call to platform_get_resource adjacent to the call to
devm_ioremap_resource to make the connection between them more clear.

A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)

* Fix version recognition in elantech_set_properties

  The new hardware reports itself as v7 but the packets'
  structure is unaltered.

* Fix packet type recognition in elantech_packet_check_v4

  The bitmask used for v6 is too wide, only the last three bits of
  the third byte in a packet (packet[3] & 0x03) are actually used to
  distinguish between packet types.
  Starting from v7, additional information (to be interpreted) is
  stored in the remaining bits (packets[3] & 0x1c).
  In addition, the value stored in (packet[0] & 0x0c) is no longer
  a constant but contains additional information yet to be deciphered.
  This change should be backwards compatible with v6 hardware.

The OLPC XO-1.75 and XO-4 laptops include a PS/2 touchpad and an AT
keyboard, yet they do not have a hardware PS/2 controller. Instead, a
firmware runs on a dedicated core ("Security Processor", part of the SoC)
that acts as a PS/2 controller through bit-banging.

Communication between the main cpu (Application Processor) and the
Security Processor happens via a standard command mechanism implemented
by the SoC. Add a driver for this interface to enable keyboard/mouse
input on this platform.
