Generic battery handling code is spread between the pen and pad codepaths
since battery usages may appear in reports for either. This makes it
difficult to concisely see the logic involved. Since battery data is
not treated like other data (i.e., we report it through the power_supply
subsystem rather than through the input subsystem), it makes reasonable
sense to split the functionality out into its own functions.
This commit has the generic battery handling duplicate the same pattern
that is used by the pen, pad, and touch interfaces. A "mapping" function
is provided to set up the battery, an "event" function is provided to
update the battery data, and a "report" function is provided to notify
the power_supply subsystem after all the data has been read. We look at
the usage itself rather than its collection to determine if one of the
battery functions should handle it. Additionally, we unconditionally
call the "report" function since there is no particularly good way to
know if a report contained a battery usage; 'wacom_notify_battery()'
will filter out any duplicate updates, however.

At the moment, our driver relies on 'wacom_battery_get_property()' to
determine the most likely battery state (e.g charging, discharging, or
full) based on the information available. It is not always possible
for the function to properly determine this, however. For instance,
whenever an AES pen leaves proximity the battery state becomes
indeterminite. This commit adds the ability to provide it with explict
state information if desired. Whenever explicit state is not required
(the majority of circumstances), WACOM_POWER_SUPPLY_STATUS_AUTO can
be used in its place.
Three uses of explicit battery status are added: two wireless disconnect
paths and the AES case mentioned above.

In addition to its USB interface, the second-generation Intuos Pro
includes a Bluetooth radio that offers two pairing interfaces: classic
and low-energy. The classic interface functions just like the earlier
Bluetooth-enabled Intuos4 and Graphire4 tablets, appearing as a HID device
that our driver can work with. The low-energy interface is intented to
be used by userspace applications that make use of its paper-to-digital
capabilities.
Despite the USB interface using Wacom's new vendor-defined HID usages,
the Bluetooth interface provides us with useless black-box "blob"
report descriptors like past devices. We thus have to explicitly add
support for the PIDs and reports used.
These devices pack a /lot/ of information into a single Bluetooth
input report. Each report contains up to seven snapshots of the pen
state, four snapshots of the touch state (of five touches each), pad
state, and battery data. Thankfully this isn't too hard for the driver
to report -- it just takes a fair amount of code to extract!

Many of Wacom's display tablets include an "outbound" area where pen
digitizing is possible but outside of the display area. To accommodate
such sensors in the HID_GENERIC codepath, we add support for the

values of the X and Y axes accordingly, similar to what is done in

Many of Wacom's display tablets include an "outbound" area where pen
digitizing is possible but outside of the display area. To ensure that
pen coordinates are mapped to the correct on-screen location, the driver
sets the minimum and maximum axis values of X and Y to those coordinates
which coincide with the screen edge. These values are simply the
hardware minimum/maximum plus/minus the outbound size for a particular
edge.
When outbound support was added/updated in ac414da, fa77034, and
ecd618d, we decided to have the wacom_features structs store the desired
minimum and maximum values directly. In hindsight, this was perhaps not
the best choice since it has allowed minor errors to crop up unnoticed.
Some tablets have had their coordinates over-corrected (e.g. most of the
devices "fixed" in ecd618d were already adjusted in ac414da), while
others never had a correction applied (e.g. the ISDv5 325, whose
declared maximum the hardware maximum instead of the outbound maximum).
A less error-prone method of handling the outbound is to let the driver
calculate the correct minimum/maximum values by providing it with both
the actual hardware maximums and the size of the outbound on each edge.
These values are more easy to verify as correct since the values can be
trivially compared against specifications.
This patch reverts the declared maximum values to the actual hardware
maximums, e.g. as declared prior to ac414da (values for these and other
display tablets that were subsuquently introduced have been verified
against specs). Per-edge outbound sizes are stored in the wacom_features
struct as offset_{left,right,top,bottom} and used in combination with
the hardware ranges to calculate effective axis ranges for ABS_X and
ABS_Y.

Wacom's professional tablets beginning with the Intuos4 are capable of
reporting an intermediate degree of proximity where the pen is no longer
close enough to communicate with ("in prox"), but still close enough to
be sensed ("in range"). This additional state is particularly useful for
performing palm rejection as it allows the driver to disable the touch
sensor while the pen is a greater distance from the tablet.
Like other professional tablets, the new MobileStudio Pro also reports
this intermeidate "in range" proximity state. Its descriptor assigns
usage 0xff0d0036 to this bit. Normally 'wacom_equivalent_usage' would
translate this to the standard HID "Quality" usage, but since this has
a different meaning we have it explicitly ignore the usage and define
it ourselves as "Sense" (since "In Range" is already defined by the
HID standard and interpreted by our driver as meaning "in prox").

Wacom's new "MobileStudio Pro" tablets are the first devices in their
branded product line-up to include a usable HID descriptor for the pen
interface. Like prior branded products, the device can operate in one
of two modes: 'Standard HID', and 'Wacom Custom HID'. Although the
first mode is usable by the HID_GENERIC codepath as-is (huzzah!), it is
subject to some restrictions -- most notably pressure being limited
to 2048 levels instead of 8192. To ensure tablets that include support
for Custom HID mode work optimally, we add support for its usages and
switch the device to Custom HID mode if possible.
The usages defined for Custom HID mode are often numerically similar to
their standard HID equivalents, allowing us to write a simple translation
function that takes arbitrary HID usages as input and which returns
the corresponding standard HID usage as output (if one exists). Switching
on this translated usage instead of the actual usage allows the existing
cases to apply to both modes of operation without having to explicitly
define every Custom HID usage.

Our loose use of "pen" and "digitizer" in the naming of several of our
vendor-defined usages may be a source of confusion given that the terms
have specific meaning within the HID specification. "Pen" specifically
refers to "an integrated display that allows the use of a stylus" (e.g.
something like a tablet PC or Cintiq) wheras "Digitizer" is a better
fit for opaque tablets like an Intuos.
While we're at it, go ahead and rename the definitions to make them more
distinct and better match up with the convention used by HID (e.g. the use
of '_UP_' for usage pages) and make them more distinct.

If a touchscreen contains both multitouch and single-touch reports in its
descriptor in that order, the driver may overwrite information it saved
about the format of the multitouch report. This can cause the report
processing code to get tripped up and send an incorrect event stream to
userspace.
In particular, this can cause last_slot_field to be overwritten with the
result that the driver prematurely assumes it has finished processing a
slot and sending the ABS_MT_SLOT event at the wrong point in time,
associating events for the current contact with the following contact
instead.
To prevent this from occurring, we update the value of last_slot_field
durring the pre_report phase to ensure that it is correct for the report
that is to be processed.

The cached indicies 'cc_index' and 'cc_value_index' introduced in 1b5d514
are only valid for a single report ID. If a touchscreen has multiple
reports with a HID_DG_CONTACTCOUNT usage, its possible that the values
will not be correct for the report we're handling, resulting in an
incorrect value for 'num_expected'. This has been observed with the Cintiq
Companion 2.
To address this, we store the ID of the report those indicies are valid
for in a new 'cc_report' variable. Before using them to get the expected
contact count, we first check if the ID of the report we're processing
matches 'cc_report'. If it doesn't, we update the indicies to point to
the HID_DG_CONTACTCOUNT usage of the current report (if it has one).

WACOM_QUIRK_NO_INPUT is a signal to the driver that input devices
should not be created for a particular device. This quirk was used by
the wireless receiver to prevent any devices from being created during
the initial probe (defering it instead until we got a tablet connection
event in 'wacom_wireless_work').
This quirk is not necessary now that a device_type is associated with each
device. Any input device allocated by 'wacom_allocate_inputs' which is
not necessary for a particular device is freed in 'wacom_register_inputs'.
In particular, none of the wireless receivers devices have the pen, pad,
or touch device types set so the same effect is achieved without the need
to be explicit.
We now return early in wacom_retrieve_hid_descriptor for wireless devices
(to prevent the device_type from being overridden) but since we ignore the
HID descriptor for the wireless reciever anyway, this is not an issue.

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

This patch introduces no functional changes.
