This changes how the touch packets for Intuos5 and 3rd-gen Bamboo
are interpreted, so that proper values for the MAJOR and MINOR
axes are reported. Instead of using the amplitude field (data[6]),
we use the size field (data[5]) and do some calculation to
transform it from a scaled-down area into axis lengths.
Note that even though we assume a circular contact, both MAJOR and
MINOR are reported since the resolution of the X and Y axes differ.

Use of the in-kernel tracking code to convert the driver to MT-B.
With ten fingers on the pad, the in-kernel tracking adds approximately
25 us to the maximum irqsoff latency. Under normal workloads, however,
the tracking has no measurable effect.

The logical scale is used to produce special finger width values to
userspace, but has become an unnecessary restriction for everything
else. Also, the bcm5974 trackpads are very accurate and work well
without hysteresis.
This patch simplifies the driver and device data by removing the
logical scale, and by moving the special synaptics code out of the
main path. Also add the orientation range, needed in a subsequent
patch, to the device configuration.

The early generations with this trackpad used the separate mouse
interface to produce button events. With the introduction of the
button pads, this information was moved to the trackpad interface,
leaving the mouse interface unused. The driver is still setting up
both interfaces, which has not caused any problems - until now.
It turns out that without the CONFIG_USB_EHCI_TT_NEWSCHED option, the
driver may return an ENOSPC upon bt_urb submission, resulting in a
failure to open the device. This happens everytime on the MacBookPro
Retina (and likely on other mid-2012 models), but earlier MacBook
models seem to work fine.
This patch skips the bt_urb setup for TYPE2 devices, which arguably
should have been done in the first place.

With the INPUT_MT_TRACK flag set, the function input_mt_assign_slots()
can be used to match a new set of contacts against the currently used
slots. The algorithm used is based on Lagrange relaxation, and performs
very well in practice; slower than mtdev for a few corner cases, but
faster in most commonly occuring cases.

Most MT drivers perform the same actions on frame synchronization.
Some actions, like dropping unseen contacts, are also unnecessarily
complex. Collect common frame synchronization tasks in a new function,
input_mt_sync_frame(). Depending on the flags set, it drops unseen
contacts and performs pointer emulation.
With init flags and frame synchronization in place, most MT drivers
can be simplified. First out are the bcm5974 and hid-multitouch
drivers, following this patch.

On heavy event loads, such as a multitouch driver, the irqsoff latency
can be as high as 250 us. By accumulating a frame worth of data
before passing it on, the latency can be dramatically reduced. As a
side effect, the special EV_SYN handling can be removed, since the
frame is now atomic.
This patch adds the events() handler callback and uses it if it
exists. The latency is improved by 50 us even without the callback.

The events-per-packet estimate has so far been used by MT devices
only. This patch adjusts the packet buffer size to also accomodate the
KEY and MSC events. Keyboards normally send one or two keys at a
time. MT devices normally send a number of button keys along with the
MT information. The buffer size chosen here covers those cases, and
matches the default buffer size in evdev. Since the input estimate is
now preferred, remove the special input-mt estimate.

Andreas Bombe reported that the added ktime_t overflow checking added to
timespec_valid in commit 4e8b14526ca7 ("time: Improve sanity checking of
timekeeping inputs") was causing problems with X.org because it caused
timeouts larger then KTIME_T to be invalid.
Previously, these large timeouts would be clamped to KTIME_MAX and would
never expire, which is valid.
This patch splits the ktime_t overflow checking into a new
timespec_valid_strict function, and converts the timekeeping codes
internal checking to use this more strict function.

Power gating is per crtc pair, but the powergating registers
should be called individually. The hw handles power up/down
properly. The pair is powered up if either crtc in the pair
is powered up and the pair is not powered down until both
crtcs in the pair are powered down. This simplifies
programming and should save additional power as the previous
code never actually power gated the crtc pair.
