HID Sensor Spec defines two usage ids for custom sensors
HID_USAGE_SENSOR_TYPE_OTHER_CUSTOM (0x09, 0xE1)
HID_USAGE_SENSOR_TYPE_OTHER_GENERIC(0x09, 0xE2)
In addition the standard also defines usage ids for custom fields.
The purpose of these sensors is to extend the functionality or provide a way to
obfuscate the data being communicated by a sensor. Without knowing the mapping
between the data and its encapsulated form, it is difficult for an driver to
determine what data is being communicated by the sensor. This allows some
differentiating use cases, where vendor can provide applications. Since these
can't be represented by standard sensor interfaces like IIO, we present these
as fields with
- type (input/output)
- units
- min/max
- get/set value
In addition an dev interface to transfer report events. Details about this
interface is described in /Documentation/hid/hid-sensor.txt. Manufacturers
should not use these ids for any standard sensors, otherwise the the
product/vendor id can be added to black list.

In the unlikely case of hdev vanishing while hid_debug_events_read() was
sleeping, we can't really break out of the case switch as with other cases,
as on the way out we'll try to remove ourselves from the hdev waitqueue.
Fix this by taking a shortcut exit path and avoiding cleanup that doesn't
make sense in case hdev doesn't exist any more anyway.

The Logitech T650 used to report 3 fingers swipes to the up as a press on the
Super key. When we switched the touchpad to the raw mode, we also disable such
firmware gesture and some users may rely on it.
Unfortunately, 3 finger swipes are still not supported in most of the Linux
environments, which means that we disabled a feature of the touchpad.
Allow users to revert the raw reporting mode and keep going with the firmware
gestures by providing a new module parameter.

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.

If noone listens to the input device when a tool comes in proximity,
the tablet does not send the in-prox event when a client becomes available.
That means that no events will be sent until the tool is taken out of
proximity.
In this situation, ask for the report WACOM_REPORT_INTUOSREAD which will
read the corresponding feature and generate an in-prox event.
To make some generation of hardware working, we need to unset the
quirk NO_GET set by hid-core because the interfaces are seen as "boot
mouse".
We don't schedule this read in a worker while we are in an IO interrupt.
We know that usbhid will do it asynchronously. If this is triggered by
uhid, then this is obviously a client side bug :)

For defining enumeration values like report or power status events, the
enumeration usage ids are enclosed in a logical collection. In this case we
need to match logical usage id for pending read on this usage id. For example,
in the below field, when read is requested for 0319, the report will
contain one of the status usages like 850, 851 etc. In this case the raw
event will not match 0319. So when logical collection matches, then wake
up the pending thread.

Logical(Sensor.0319)
