Instead of having a single 'input_dev' device that will take either pen
or touch data depending on the type of the device, create seperate devices
devices for each. By splitting things like this, we can support devices
(e.g. the I2C "AES" sensors in some newer tablet PCs) that send both pen
and touch reports from a single endpoint.

Historically, both the touch and pad tools would have shared the
'BTN_TOOL_FINGER' type. Any time you needed to distinguish the two, you
had to use some other bit of knowledge (e.g. that the pad was on the same
interface as the pen, and thus 'touch_max' would be zero).
To make these checks more readable, we introduce WACOM_DEVICETYPE_PAD.
Although we still have to rely on other bits of knowledge to set this
bit on the right interface (since it cannot be detected from the HID
descriptor), it can be done just once inside 'wacom_setup_device_quirks'.
This patch introduces no functional changes.

The USB devices that this driver has historically supported segregate the
pen and touch portions of the tablet. Oftentimes the segregation would be
done at the interface level, though on occasion (e.g. Cintiq 24HDT) the
tablet would combine two totally independent USB devices behind an internal
USB hub. Because pen and touch never shared the same interface, it made
sense for the 'device_type' to store a single value: "pen" or "touch".
Recently, however, some I2C devices have been created which combine the
two. A first step to accomodating this is to expand 'device_type' so that
it can represent two (or potentially more) types simultaneously. To do
this, we treat it as a bitfield and set/check individual bits rather
than using the '=' and '==' operators.
This should not result in any functional change since no supported devices
(that I'm aware of, at least) have HID descriptors that indicate both
pen and touch reports on a single interface.

Currently, we assume a device_type of BTN_TOOL_PEN before scanning the
HID descriptor and then change the device_type if what we discover
proves that assumption wrong. This way of doing things makes it more
difficult to figure out if a device (particularly a HID_GENERIC device)
actually does tablet/touch input or is something completley different.
This patch leaves device_type at its initial value of 0 and then calls
'wacom_parse_hid' for every device (not just those that have touch).
As we map the usages, we can set the device_type as before. After we're
finished, we can then check if the value is still zero and do whatever
is most appropriate.
Detecting the pen can be a little tricky on most Wacom devices because
the descriptors describe opaque blobs. Fortunately, older Wacom tablets
have the HID_DG_DIGITIZER usage on the pen's application collection and
newer tablets seem to have a similar vendor-defined usage that we can
trigger on.

The quirk was added for devices that support both pen and touch. It decides if
a device supports multiple inputs by hardcoded feature type. However, for some
devices, we do not know if they support both before accessing their HID
descriptors.
This patch relies on dynamically assigned device_type to make the decision.
Also, we make it certain that wacom_wac->shared is always created. That is, the
driver will not be loaded if it fails to create wacom_wac->shared.

Declare the POWER_SUPPLY_PROP_PRESENT property to provide userspace
with a way to determine if the battery on a wireless tablet is plugged
in. Although current wireless tablets do not explicitly report this
information, it can be inferred from other state information. In
particular, a battery is assumed to be present if any of the following
are true: a non-zero battery level reported, the battery is reported as
charging, or the tablet is operating wirelessly.
Note: The last condition above may not strictly hold for the Graphire
Wireless (it charges from a DC barrel jack instead of a USB port), but I
do not know what is reported in the no-battery condition.

The stylus of this device works just fine out of the box.
The touch is seen by default as a mouse with relative events and some
gestures.
The wireless and the wired version have slightly different firmwares, but
the debug mode 2 on the feature 2 is common to the 2 devices. In this mode,
all the reports are emitted through the debug interface (pen, raw touch
and mouse emulation), so we have to re-route manually the events.
We keep the Pen interface as a HID_GENERIC one because it works, and only
parse the raw touches while discarding the mouse emulation & gestures.
Switching the default in raw mode allows us to have a consistent user
experience accross all the multitouch touchpads (and enable the touch part
of the devices).
Note that the buttons of this devices are reported through the touch
interface. There is no 'Pad' interface. It seemed more natural to have
the BTN_LEFT and BTN_RIGHT reported with the touch because they are
placed under the touch interface and it looks like they belong to the
touch part.

The Bamboo PAD in debug mode needs to re-route events from the debug
interface to the Pen interface. This can be easily done with
hid_input_report(), but that means that we need to keep a reference to
the various hid_devices.
There should be only one touch and one pen interface per physical tablet,
so there is no need to keep a list of hid-devices, plain pointers are
sufficient.

valid data is reported when tool enters proximity; or before out of proximity

While entering proximity, In Range means a pen is detected. This information
can be used for palm/touch rejection on both pen and touch enabled devices.
While exiting, it means the tool has reached its maximum detectable distance.

entire HID report, which practically means that only data about the last
contact in a report will ever be provided to userspace. This patch uses

end of each contact; when such a field is encountered all the stored

ISDv4 and v5 are plain HID devices. We can directly implement a generic
HID parsing/handling and remove the need to manually add those PID in
the list of supported devices.
This patch implements the pen support only. The finger part will come in
a later patch.
To be properly notified of an .event() and a .report(), we need to force
hid-core to go through the HID parsing. By default, wacom.ko binds only
hidraw, so the hid parsing is not done by hid-core. When a true HID device
is there, we add the flag HID_CLAIMED_DRIVER to hid->claimed which will
force hid-core to parse the incoming reports.
(Note that this can be easily backported by directly setting the .claimed
flag to HID_CLAIMED_DRIVER even if hid-core does not support
HID_CONNECT_DRIVER)
