Adding a wait before the wakeup signal.
As a precautionary measure sanity check the current sensor mode. If
needed reset it to "dual".
When the device is responding poorly and needs the wakeup call, it was
missing it. Giving it a chance to settle first improves the chances
that signal gets through.

This patch merges the hid-egalax driver into hid-multitouch. There
are two types of devices support by the hid-egalax driver: resistive
and capacitive. Here, they are implicitly distinguished by the absence
of a HID_DG_CONTACTCOUNT field in the latter, so no special code path
needs to be introduced.
As a side effect, this patch fixes the broken suspend/resume behavior
in the old driver.

This device does not tolerate delayed opening and goes into a coma if
we try to that. Ubuntu even has a crutch for udev that opened the device
upon seeing it for the first time, but it did not work if we happened to
boot with the device attached, since by the time userspace got around
opening the device it was too late. Let's start the device immediately
to deal with this issue.

The magic trackpad and mouse both report touch orientation in opposite
direction to the bcm5974 driver and what is written in
Documents/input/multi-touch-protocol.txt. This patch reverts the
direction, so that all in-kernel devices with this feature behave the
same way.
Since no known application has been utilizing this information yet, it
seems appropriate also for stable.

When the multi input quirk is set, there is a new input device
created for every feature report. Since the idea is to present
features per hid device, not per input device, revert back to
the original report loop and change the feature_mapping() callback

The safest quirk for a device (the one that works out of the box for
most of them) is MT_QUIRK_NOT_SEEN_MEANS_UP. Indeed, it does not
make any assumption on the device. When adding a new device, we can
easily test it against MT_CLS_DEFAULT, and then optimize it with other
quirks: that's why no device use MT_CLS_DEFAULT right now.

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.
This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).
Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.
