This driver is responsible for implementing ISH HID client, which
gets HID description and report. Once it has completely gets
report descriptors, it registers as a HID LL drivers. This implements
necessary callbacks so that it can be used by HID sensor hub driver.

The ISH transport layer (ishtp) is a bi-directional protocol implemented
on the top of PCI based inter processor communication layer. This layer
offers:
- Connection management
- Flow control with the firmware
- Multiple client sessions
- Client message transfer
- Client message reception
- DMA for RX and TX for fast data transfer
Refer to Documentation/hid/intel-ish-hid.txt for
overview of the functionality implemented in this layer.

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.

Touch arbitration is always on in wacom.ko. However, there are

We should provide an option for userland to decide if they want
arbitration on or off.
This patch sets default touch_arbitration to on since most userland
apps are not ready to process pen and touch events simultaneously.
In the future, when userland is ready to accept pen and touch events
together, we will switch default touch_arbitration to off.

The 'oVid' and 'oPid' variables used by wacom_are_sibling are a hacky
solution to the problem of the driver historically having few good
heuristics to use in determining if two devices should be considered
siblings or not. While it works well enough for explicitly supported
devices, it offers no help for HID_GENERIC devices. Now that we have
a bit more information (e.g. direct/indirect) available to us though,
we should make use of it it to improve the pairing of such devices.

When upowerd detects a new device, it tries to map this new device to
an input to guess its kind. It works OK for wired tablets when the
wireless module and its battery are attached, but not so well when
connected over wireless.
In that case, the battery is attached to the wireless HID node, not
the Pen or Pad HID node. So there is no input node as a parent of the
reported battery, which means it will be showed as a computer battery
in gnome-control-center.
If we set the power supply type to USB, upowerd has a heuristic that
detects "wacom_" in the name of the power_supply, and set the type to
tablet. So it's now clear that the reported battery of from a tablet.

There is a bug (?) in devm_led_classdev_register() in which its increments
the refcount of the parent. If the parent is an input device, that means
the ref count never reaches 0 when devm_input_device_release() gets called.
This means that the LEDs and all the devres resources attached to the
input device are not released.
Manually force the release of the group so that the leds are released once
we are done using them.

Thanks to devres, we can now afford to create more than one input node
without having to overload the remove/failure paths. Having one input
node per remote is something which should have been implemented from start
but the probability of having users with several remotes is quite low.
Anyway, still, better looking at the future and implement things properly.
Remote input nodes will be freed/unregistered magically as they are
created in the devres group &remote->remotes[index].
We need to open the hid node now that the remotes are dynamically
allocated.
