b1f466a90c HID: wacom: generic: add the "Report Valid" usage
Wacom Bluetooth reports contain multiple pen frames per report.
Each frame contains a flag indicating if the frame is valid.
Future Wacom devices with this type of report may contain HID
descriptors, add support for this usage to the generic codepath
of the Wacom driver.

8341720642 HID: wacom: Queue events with missing type/serial data for later processing
Userspace expects to receive tool type and serial number information
for the active pen in the very first kernel report, if such data is
supported by the hardware. While this expectation is not an issue for
EMR devices, AES sensors will often send several packets worth of in-
range data before relaying type/serial data to the kernel. Sending this
data "late" can result in proximity-tracking issues by xf86-input-wacom,
or an inability to distinguish different pens by input-wacom.

Options for dealing with this situation include ignoring reports from
the tablet until we get the necessary data, or using the information
from the last-seen pen instead of the (eventual) real data. Neither
option is particularly attractive: the former results in truncated
strokes and the latter causes issues with switching between pens.

This commit instead opts to queue up events with missing information
until we receive a report which contains it. At that point, we can
update the driver's state variables (id[0] and serial[0]) and replay
the queued events.

99acedadde HID: wacom: Properly handle AES serial number and tool type
Current AES sensors relay tool type and serial number information with
a different set of usages than those prescribed by the modern (i.e.
MobileStudio Pro and newer) EMR tablet standard. To ensure the driver
properly understands these usages, we modify them to be compatible.
The identifying information is split across three consecutive fields:
a 16-bit WACOM_HID_WT_SERIALNUMBER (which is more accurately described
as WACOM_HID_WD_TOOLTYPE), a 32-bit HID_DG_TOOLSERIALNUMBER, and an
8-bit 0xFF000000 (which should be WACOM_HID_WD_SERIALHI). While we're
at it, we also define proper min/max values since may may be undefined
on some devices.

9e429d5649 HID: wacom: generic: Send BTN_STYLUS3 when both barrel switches are set
The Wacom Pro Pen 3D includes a third barrel switch which is intended to
be particularly useful in applications where one frequency uses pan, zoom,
and rotate to navigate around a scene or model. The pen is compatible with
the MobileStudio Pro, 2nd-gen Intuos Pro, and Cintiq Pro. When the third
button is pressed, these devices set both the HID_DG_BARRELSWITCH and
HID_DG_BARRELSWITCH2 usages since their HID descriptors do not include a
usage specific to the button.

Rather than send both BTN_STYLUS and BTN_STYLUS2 when the third button is
pressed, userspace (libinput) has requested that we detect this condition
and report a newly-defined BTN_STYLUS3 event instead. We could define a
quirk specific to devices compatible with the Pro Pen 3D, but the liklihood
of seeing both barrel switch bits set with other pens/devices is low enough
to not worry about (pens mechanically prevent accidental activation of
multiple switches).

885e89f601 HID: wacom: generic: Recognize WACOM_HID_WD_PEN as a type of pen collection
The WACOM_PEN_FIELD macro is used to determine if a given HID field should be
associated with pen input. This field includes several known collection types
that Wacom pen data is contained in, but the WACOM_HID_WD_PEN application
collection type is notably missing. This can result in fields within this
kind of collection being completely ignored by the `wacom_usage_mapping`
function, preventing the later '*_event' functions from being notified about
changes to their value.

5ac3d4ae58 HID: wacom: generic: Refactor generic battery handling
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.

16e4598905 HID: wacom: Add ability to provide explicit battery status info
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.

4922cd26f0 HID: wacom: Support 2nd-gen Intuos Pro's Bluetooth classic interface
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!

e779ef2310 HID: wacom: Fix sensor outbounds and redefine as offsets from each edge
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.

61ce346a21 HID: wacom: generic: Add support for vendor-defined "Sense" usage
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").

c9c095874a HID: wacom: generic: Support and use 'Custom HID' mode and usages
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.

While we're at it, go ahead and rename the definitions to make them more

of '_UP_' for usage pages) and make them more distinct.

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

e5bc8eb1b0 HID: wacom: Add WACOM_DEVICETYPE_DIRECT for Cintiqs and similar
"Direct" input devices like Cintiqs and Tablet PCs set the INPUT_PROP_DIRECT
property to notify userspace that the sensor and screen are overlaid. This
information can also be useful elsewhere within the kernel driver, however,
so we introduce a new WACOM_DEVICETYPE_DIRECT that signals this to other
kernel code.

59d69bc821 HID: wacom: EKR: have one power_supply per remote
Previously, all the remotes attached to the same receiver would share the
same power_supply. That's not good as the remotes will constantly change
the battery information according to their own state.

To have something generic enough, we introduce struct wacom_battery
which regroups all the information we need for a battery.

bef7e20006 HID: wacom: Add fuzz factor to distance and tilt axes
The fuzz present on the distance and tilt axes is noticable when a puck is
present, and userspace (specifically libinput) would like the ability to
filter out the noise. To facilitate this, we assign a fuzz value of '1'
for the distance and tilt axes. This is large enough to cover most of the
natural variation in distance value as the puck is moved around, and
enough to cover the jitter in rotation (reported through tilt axes) when
the puck is left alone.

326ea2a905 HID: wacom: Support switching from vendor-defined device mode on G9 and G11
A tablet PC booted into Windows may have its pen/touch hardware switched
into "Wacom mode" similar to what we do with explicitly-supported hardware.
Some devices appear to maintain this state across reboots, preventing their
use with the generic HID driver. This patch adds support for detecting the
presence of the mode switch feature report used by devices based on the G9
and G11 chips and has the HID codepath always attempt to reset the device
back to sending standard HID reports.

0bbfe28ad0 HID: wacom: Use correct report to query pen ID from INTUOSHT2 devices
Unlike other tablets which are compatible with the wacom_intuos_irq handler,
INTUOSHT2 devices provide pen ID with report ID 8 instead of 5. To ensure
wacom_intuos_schedule_prox_event works as intended for these tablets, we
must be sure it uses the correct report ID in this case.

499522c8c0 HID: wacom: Tie cached HID_DG_CONTACTCOUNT indices to report ID
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).
