Sometime valid events may not be supported by the driver yet. Make
sure we don't process them when the code is not ready.
This fix prevents a kernel panic due to unsupported HID events.

The eraser end of the 8K pen available for the MobileStudio Pro has a tool
ID of 0x84a. The 'wacom_intuos_get_tool_type' function does not currently
recognize this ID, causing it to return BTN_TOOL_PEN rather than
BTN_TOOL_RUBBER. This does not cause a problem for the MobileStudio Pro
since, as a HID_GENERIC device, the driver relies on the state of the
HID_DG_INVERT usage instead. It would, however, cause problems if the pen
is used with devices that use the traditional 'wacom_intuos_irq' codepath
instead.

The "Steering" usage (HID_UP_SIMULATION | 0xc8) is defined in HUT 1.12 as
follows:
"A steering wheel is a single degree-of-freedom device that rotates about
an axis. The zero position is always the neutral or 'straight ahead'
position, with positive values turning clockwise and negative values
turning counterclockwise. If the Coordinate Values Wrap attribute is
set, the steering wheel can be turned past 360 degrees."
The hidinput_configure_usage function canonically maps this usage to the
ABS_WHEEL axis, but hidinput_calc_abs_res does not recognize this axis
as one for which it can calculate a resolution. This effectively prevents
wheels from being assigned a proper resolution that userspace can use
to determine the precise angle of input.
This commit adds ABS_WHEEL as a rotational axis to hidinput_calc_abs_res.

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
necessary vendor-defined HID feature usages and adjust the min/max
values of the X and Y axes accordingly, similar to what is done in
the non-generic codepath.

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.

The 'wacom_intuos_inout' function incorrectly assmebles tool IDs from the
proximity report, shifting the higher values of the ID four bits farther
than intended. This problem was not detected until too late, but has not
caused any issues since the incorrect IDs still fit in a 32-bit integer
and userspace programs have not required the value to match the hardware
(just that the values are unique and constant).
The tool IDs reported by the new MobileStudio Pro (or any future
HID_GENERIC device that supports them) do not suffer from the same
assembly issue, however. In order for 'wacom_intuos_get_tool_type' to
work for with both codepaths, we correct this issue internally and
have 'wacom_intuos_general' only mangle the ID when it is posted to
userspace.

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").

The vendor-defined 0xFF0D01032 ("Distance") usage is nearly equivalent to
HID_GD_Z, except that the axis direction is inverted. Unlike HID_GD_Z which
increases in value as the pen-to-surface distance is decreased, this usage
decreases. Treat this usage as a special case to ensure we don't invert the
scale to be ABS_DISTANCE compatible like we do for HID_GD_Z.

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.

The HID standard defines usages that allow digitizers to report the pen's
height, tilt, and rotation and which are used by Wacom's new "MobileStudio
Pro" devices.
Note that 'hidinput_calc_abs_res' expects ABS_Z (historically used by our
driver to report twist) to have linear units. To ensure it calculates a
resolution with the actually-angular units provided in the HID descriptor
we nedd to lie and tell it we're calculating it for the (rotational) ABS_RZ
axis instead.

ISDv4 devices have long supported reporting data from each of two barrel
switches, but HID_DG_BARRELSWITCH2 itself was only recently standardized.
Prior to its adoption, ISDv4 devices would associate the bit indicating
the state of the second barrel switch with the "Undefined" 0x000D0000
usage. Although most such devices have explicit support, a few use the
HID_GENERIC codepath which ignores the "Undefined" usage.
This patch adds code which detects the presence of a pre-standard second
barrel switch and corrects the usage value so that the HID_GENERIC code
will declare its presence and report its state.

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.

This adds support for the THQ uDraw tablet for the PS3, as
4 separate device nodes, so that user-space can easily consume
events coming from the hardware.
Note that the touchpad two-finger support is fairly unreliable,
and a right-click can only be achieved with a two-finger tap
with the two fingers slightly apart (about 1cm should be enough).

The DS4 side of hid-sony used the hid-core layer to assign buttons
and axes based on the HID report descriptors. The default mapping
was strange e.g. right stick using ABS_Z/ABS_RZ or the physical
'south button' being reported as BTN_EAST etcetera.
This patch makes the DS4 side ofi the hid-sony driver comply to
the Linux game controller spec as suggested in a discussion with
Dmitry on the linux-input list.
Currently the main user of the DS4 is the SDL2 library, which has
a mapping table using vendor/device/version as a key. In order to
not break SDL2 we discussed adjusting the version number, so it
can have both mappings. This was discust on linux-input and we
discussed privately with SDL2 developers.

The dualshock 4 supports both analog sticks of which one uses
ABS_X/_Y and a touchpad. In a recent discussion with Dmitry about
some input-mt changes we proposed for disabling pointer emulation from
input_mt_sync_frame, Dmitry mentioned ABS_X/_Y should report the
same data as ABS_MT_POSITION_X/_Y. The current driver is mixing axes
for different subdevices. It was suggested to make the touchpad
its own sub-device.
This patch turns the touchpad into its own device. In addition
this patch also moves the button underneath the touchpad into
the new device. It felt like this button should be part of the
device. No known user space application (not even SDL2) seems to
be using it.

A previous patch moved most input initialization from sony_probe to
sony_input_configured to avoid some race conditions. The driver has some
special logic to prevent the device to get registered twice in case the
user connects it both over Bluetooth and USB. When this condition
happens sony_input_configured returns a failure, but sony_probe continues
as hid_hw_start doesn't fail. As was discussed on linux-input, it is
acceptable for this function to fail.
This patch adds a check for the HID_CLAIMED_INPUT flag within sony_probe
to determine whether initialization succeeded correctly. The flag is
not set by the HID layer when sony_input_configured fails.

The motion sensor values are 16-bit, so make the value range match.
It is hard to reach the upper values, but they can be reached. At
least the current accelerometer value of 8192 is very easy to pass.
It is still not nice that the motion sensors live in no man's land
in between ABS_MISC and ABS_MT_SLOT, but that's something for another
time, which the proposed ABS_ACCEL_*/ABS_GYRO_* were meant for.

Early on the sony_probe function calls hid_hw_start to start the hardware.
Afterwards it issues some hardware requests, initializes other functionality
like Force Feedback, power classes and others. However by the time
hid_hw_start returns, the device nodes have already been created, which leads
to a race condition by user space applications which may detect the device
prior to completion of initialization. We have observed this problem many
times, this patch fixes the problem.
This patch moves most of sony_probe to sony_input_configured, which is called
prior to device registration. This fixes the race condition and the same
approach is used in other HID drivers.

external buttons have some weird usage mapping:

- Button 3 Indicates Button State for external button for secondary

So in the current state, the buttons are mapped to right and middle.

We already have in place a quirk for Windows 8 devices, but it looks
like the Surface Cover are not conforming to it.
Given that we are only interested in 3 feature reports (the ones that
the Windows driver retrieves), we should be safe to unconditionally apply
the quirk to everybody.
In case there is an issue with a controller, we can always mark it as such
in the transport driver, and hid-multitouch won't try to retrieve the
feature report.

With the previous hid-input fix, there is now a full support of the Type

also remove it from the list of ushbid quirks.

The purpose of HID_QUIRK_MULTI_INPUT is to have an input device per
report id. This is useful when the HID device presents several HID
collections of different device types.
The current implementation of hid-input creates one input node per id per
type (input or output). This is problematic for the LEDs of a keyboard as
they are often set through an output report. The current code creates
one input node with all the keyboard keys, and one other with only the
LEDs.
To solve this, we use a two-passes way:
- first, we initialize all input nodes and associate one per report id
- then, we register all the input nodes
