d72e64ec0b Input: migor_ts - convert to dev_pm_ops
There is a general move towards the use of dev_pm_ops rather than
bus specific suspend APIs as this simplifies both the bus and PM core
implementations. Convert the migor_ts driver over.

Compile tested only.

OLPC has switched to a Synaptics touchpad.  It turns out that it's

4f56ce929c Input: synaptics - ignore bogus mt packet
In multitouch mode, at least one device (fw: 7.4 id: 0x1c0b1) sometimes
sends a final main packet with x == 1. Since the normal values are above
1472, this is clearly bogus. At the same time, a two-finger touch is
signaled, even though only one finger was on the pad to begin with. This
patch ignores the packet altogether, removing the problem.

fec6e5252b Input: synaptics - add multi-finger and semi-mt support
The Synaptics 2.7 series of touchpads support a mode for reporting two
sets of X/Y/Pressure data (advanced gesture mode). By default, these
devices report only single finger data, depriving userspace of the
nowadays ubiquitous two-finger scroll gesture.

Enabling advanced gesture mode also enables the multi-finger report,
although the device does not claim that capability. Up to three
fingers can be reported this way.

While two or three fingers are touching, the normal packet is
prepended by a reduced finger packet of lower resolution. From the two
packets (which do not represent the actual fingers), the bounding
rectangle of the individual contacts can be extracted.  This
information is sufficient to perform scaling gestures and a limited
form of rotation gesture. The behavior has been coined semi-mt
capability, and is signaled to userspace via the INPUT_PROP_SEMI_MT
device property.

Work to decode the advanced gesture packet: Takashi Iwai.
Cleanup and testing of the original patch: Chase Douglas.
Minor cleanup and testing: Chris Bagwell.
Finalization and semi-mt support: Henrik Rydberg.

fcd3027abb Input: fix double equality sign in uevent
Looking at the uevent stream for input devices, all properties are on
the form "A=B" except the bitmap values, which are on the form
"A==B". This bug has been around at least since 2007, and the input
uevent code has been untouched since. The recent addition of device
properties suggests this is a good time for a remedy.

85b7720039 Input: introduce device properties
Today, userspace sets up an input device based on the data it emits.
This is not always enough; a tablet and a touchscreen may emit exactly
the same data, for instance, but the former should be set up with a
pointer whereas the latter does not need to. Recently, a new type of
touchpad has emerged where the buttons are under the pad, which
changes logic without changing the emitted data. This patch introduces
a new ioctl, EVIOCGPROP, which enables user access to a set of device
properties useful during setup. The properties are given as a bitmap
in the same fashion as the event types, and are also made available
via sysfs, uevent and /proc/bus/input/devices.

c5f4dec1ce input: mt: Move tracking and pointer emulation to input-mt
The drivers using the type B protocol all report tracking information
the same way. The contact id is semantically equivalent to
ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates
the driver. The situation can be improved upon by providing a common
pointer emulation code, thereby removing the need for the tracking id
in the driver.  This patch moves all tracking event handling over to
the input core, simplifying both the existing drivers and the ones
currently in preparation.

39de52104d Input: serio HIL MLC - don't deref null, don't leak and return proper error
While reviewing various users of kernel memory allocation functions I came
across drivers/input/serio/hil_mlc.c::hil_mlc_register() and noticed that:

 - it calls kzalloc() but fails to check for a NULL return before use.
 - it makes several allocations and if one fails it doesn't free the
   previous ones.
 - It doesn't return -ENOMEM in the failed memory allocation case (it just
   crashes).

This patch corrects all of the above and also reworks the only caller of
this function that I could find
(drivers/input/serio/hp_sdc_mlc.c::hp_sdc_mlc_out()) so that it now checks
the return value of hil_mlc_register() and properly propagates it on
failure and I also restructured the code to remove some labels and goto's
to make it, IMHO nicer to read.
