Bhaktipriya Shridhar c9a3a7cf95 Input: wm97xx - remove deprecated create_singletheread_workqueue
alloc_ordered_workqueue() replaces deprecated
create_singlethread_workqueue().

It queues work items via &wm->ts_reader and &wm->pen_event_work which map
to wm97xx_pen_irq_worker (handles a pen down interrupt) and
wm97xx_ts_reader (the touchscreen sample reader) respectively. Hence, an
ordered dedicated workqueue has been used.

Bhaktipriya Shridhar 62e5147568 Input: mc13783_ts - remove deprecated create_singletheread_workqueue
The workqueue "workqueue" has a single workitem(&priv->work) and hence
doesn't require ordering. Also, it is not being used on a memory reclaim
path. Hence, the singlethreaded workqueue has been replaced with the use
of system_wq.

System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.

Workitem is sync cancelled in mc13783_ts_remove() to ensure that there
are no workitems pending when the driver is disconnected.

Bhaktipriya Shridhar 24dde60f56 Input: psmouse - remove deprecated create_singletheread_workqueue
alloc_ordered_workqueue() replaces the deprecated
create_singlethread_workqueue().

There are multiple work items on the work queue viz
&priv->dev3_register_work, &priv->recalib_wq, &psmouse->resync_work,
which require execution ordering. Hence, an ordered workqueue has been
used.

The workqueue is not being used on a memory reclaim path.  Hence,
WQ_MEM_RECLAIM has not been set.

This commit removes this duplicate driver and adds the i2c ids and

This commit also adds the standard touchscreen properties as optional
properties to the edt,ft5x06 binding, these were documented in the
focaltech,ft6236 bindingi, but were missing from the edt,ft5x06 doc.

Cameron Gutman f712a5a052 Input: xpad - power off wireless 360 controllers on suspend
When the USB wireless adapter is suspended, the controllers
lose their connection. This causes them to start flashing
their LED rings and searching for the wireless adapter
again, wasting the controller's battery power.

Instead, we will tell the controllers to power down when
we suspend. This mirrors the behavior of the controllers
when connected to the console itself and how the official
Xbox One wireless adapter behaves on Windows.

Dmitry Torokhov 4097461897 Input: i8042 - break load dependency between atkbd/psmouse and i8042
As explained in 1407814240-4275-1-git-send-email-decui@microsoft.com we
have a hard load dependency between i8042 and atkbd which prevents
keyboard from working on Gen2 Hyper-V VMs.

> hyperv_keyboard invokes serio_interrupt(), which needs a valid serio
> driver like atkbd.c.  atkbd.c depends on libps2.c because it invokes
> ps2_command().  libps2.c depends on i8042.c because it invokes
> i8042_check_port_owner().  As a result, hyperv_keyboard actually
> depends on i8042.c.
>
> For a Generation 2 Hyper-V VM (meaning no i8042 device emulated), if a
> Linux VM (like Arch Linux) happens to configure CONFIG_SERIO_I8042=m
> rather than =y, atkbd.ko can't load because i8042.ko can't load(due to
> no i8042 device emulated) and finally hyperv_keyboard can't work and
> the user can't input: https://bugs.archlinux.org/task/39820
> (Ubuntu/RHEL/SUSE aren't affected since they use CONFIG_SERIO_I8042=y)

To break the dependency we move away from using i8042_check_port_owner()
and instead allow serio port owner specify a mutex that clients should use
to serialize PS/2 command stream.

In cros_ec_keyb we stored "dev" in "struct cros_ec_keyb", but this was
the EC's dev pointer and not the keyboard's.  Let's clean this up to
make it the keyboard's dev pointer.  This could be useful in future
patches but also has the nice effect of changing a few printouts to
include the name of the keyboard device instead of the EC device, so we
will see:

[    1.224648] cros-ec-keyb ff110000.spi:ec@0:keyboard-controller: valid_keys[00] = 0x14

This allows for the use of the product variable to set the input_dev->name

let's keep this quirk.

Make this a proper typed array. Drop the old allocate context code since
that is no longer used.

Note that the memops functions now get a struct device pointer instead of
the struct device ** that was there initially (actually a void pointer to
a struct containing only a struct device pointer).

This code is now a lot cleaner.

Sinclair Yeh 60842ef812 Input: vmmouse - remove port reservation
The VMWare EFI BIOS will expose port 0x5658 as an ACPI resource.  This
causes the port to be reserved by the APCI module as the system comes up,
making it unavailable to be reserved again by other drivers, thus
preserving this VMWare port for special use in a VMWare guest.

This port is designed to be shared among multiple VMWare services, such as
the VMMOUSE.  Because of this, VMMOUSE should not try to reserve this port
on its own.

The VMWare non-EFI BIOS does not do this to preserve compatibility with
existing/legacy VMs.  It is known that there is small chance a VM may be
configured such that these ports get reserved by other non-VMWare devices,
and if this ever happens, the result is undefined.

Cameron Gutman c7f1429389 Input: xpad - fix oops when attaching an unknown Xbox One gamepad
Xbox One controllers have multiple interfaces which all have the
same class, subclass, and protocol. One of the these interfaces
has only a single endpoint. When Xpad attempts to bind to this
interface, it causes an oops when trying initialize the output URB
by trying to access the second endpoint's descriptor.

This situation was avoided for known Xbox One devices by checking
the XTYPE constant associated with the VID and PID tuple. However,
this breaks when new or previously unknown Xbox One controllers
are attached to the system.

This change addresses the problem by deriving the XTYPE for Xbox
One controllers based on the interface protocol before checking
the interface number.

 "Pegasus Mobile Notetaker M210",
 "Genie e-note The Notetaker",
 "Staedtler Digital ballpoint pen 990 01",
 "IRISnotes Express" or
 "NEWLink Digital Note Taker".

Here's an example, so that you know what we are talking about:
http://www.genie-online.de/genie-e-note-2/

https://pegatech.blogspot.com/ seems to be a remaining official resource.

This device can also transfer saved (offline recorded handwritten) data and
there are userspace programs that do this, see https://launchpad.net/m210
(Well, alternatively there are really fast scanners out there :)

It's *really* fun to use as an input tablet though! So let's support this
for everybody.
