This patch adds a driver for Synaptics USB touchpad or pointing stick
devices. These USB devices emulate an USB mouse by default, so one can
also use the usbhid driver. However, in combination with special user
space drivers this kernel driver allows one to customize the behaviour
of the device.
An extended version of this driver with support for the cPad background
display can be found at
<http://jan-steinhoff.de/linux/synaptics-usb.html>.

As noted by Arve and others, since wall time can jump backwards, it is
difficult to use for input because one cannot determine if one event
occurred before another or for how long a key was pressed.
However, the timestamp field is part of the kernel ABI, and cannot be
changed without possibly breaking existing users.
This patch adds a new IOCTL that allows a clockid to be set in the
evdev_client struct that will specify which time base to use for event
timestamps (ie: CLOCK_MONOTONIC instead of CLOCK_REALTIME).
For now we only support CLOCK_MONOTONIC and CLOCK_REALTIME, but
in the future we could support other clockids if appropriate.
The default remains CLOCK_REALTIME, so we don't change the ABI.

Commit 509f87c5f5 (evdev - do not block waiting for an event if fd
is nonblock) created a code path were it was possible to use retval
uninitialized.
This could lead to the xorg evdev input driver getting corrupt data
and refusing to work with log messages like

Cypress TrueTouch(tm) Standard Product controllers are found in
a wide range of embedded devices. This driver add support for a
variety of TTSP controllers.
Since the hardware is capable of tracking identifiable contacts, multi-touch
protocol type B (stateful) is used to report contact information.
The driver is composed of a core driver that process the data sent by
the contacts and a set of bus specific interface modules. This patch
adds the base core TTSP driver.

As part of the removal of get_driver()/put_driver(), this patch
(as1510) changes driver_find(); it now drops the reference it acquires
before returning. The patch also adjusts all the callers of
driver_find() to remove the now unnecessary calls to put_driver().
In addition, the patch adds a warning to driver_find(): Callers must
make sure the driver they are searching for does not get unloaded
while they are using it. This has always been the case; driver_find()
has never prevented a driver from being unregistered or unloaded.
Hence the patch will not introduce any new bugs. The existing callers
all seem to be okay in this respect, however I don't understand the
video drivers well enough to be certain about them.

We don't actually care if the device has been runtime suspended immediately
so we can just drop the reference without waiting for any state change to
be implemented. This may allow us to avoid some suspend/resume cycles and
is a bit more friendly to the rest of the system.

Because we are using platform_device_probe() to register the driver
we do not need to assign driver's probe method. We also can mark
ske_keypad_probe(), together with ske_keypad_chip_init(), as __init
instead of __devinit.
