8c9952b26b HID: logitech-hidpp: fix negated returns
Reported by Dan Carpenter:

drivers/hid/hid-logitech-hidpp.c:359 hidpp_root_get_protocol_version() warn: should this return really be negated?
drivers/hid/hid-logitech-hidpp.c:398 hidpp_devicenametype_get_count() warn: should this return really be negated?
drivers/hid/hid-logitech-hidpp.c:417 hidpp_devicenametype_get_device_name() warn: should this return really be negated?
drivers/hid/hid-logitech-hidpp.c:524 hidpp_touchpad_get_raw_info() warn: should this return really be negated?

The problem lies in hidpp_send_message_sync() which can return 2 types of
errors depending of their sign. Adding a comment there to clarify what is
happening.

To solve that, print an error in case of a protocol problem, and raise
-EPROTO instead.

9c5c6ed7b5 HID: core: cleanup .claimed field on disconnect
When a subdriver is rmmod-ed then re-insmod-ed, the hid device is not
destroyed as it is owned by the transport layer.
So when we re-probed the device, the hid device is assumed to be already
claimed, and can lead to page faults if hid-core tries to forward the
emitted data to the to-be-created claimed node.

b905811a49 HID: usbhid: prevent unwanted events to be sent when re-opening the device
When events occurs while no one is listening to the node (hid->open == 0
and usb_kill_urb() called) some events are still stacked somewhere in
the USB (kernel or device?) stack. When the node gets reopened, these
events are drained, and this results in spurious touch down/up, or mouse
button clicks.

The problem was spotted with touchscreens in fdo bug #81781 [1], but it
actually occurs with any mouse using hid-generic or touchscreen.

A way to reproduce it is to call:

$ xinput disable 9 ; sleep 5 ; xinput enable 9

With 9 being the device ID for the touchscreen/mouse. During the "sleep",
produce some touch events or click events. When "xinput enable" is called,
at least one click is generated.

This patch tries to fix this by draining the queue for 50 msec and
during this time frame, not forwarding these old events to the hid layer.

Hans completed the explanation:
"""
Devices like mice (basically any hid device) will have a fifo
on the device side, when we stop submitting urbs to get hid reports from
it, that fifo will fill up, and when we resume we will get whatever
is there in that fifo.
"""

5989a55a4c HID: input: Fix TransducerSerialNumber implementation
The commit which introduced TransducerSerialNumber (368c966) is missing
two crucial implementation details. Firstly, the commit does not set the
type/code/bit/max fields as expected later down the code which can cause
the driver to crash when a tablet with this usage is connected. Secondly,
the call to 'set_bit' causes MSC_PULSELED to be sent instead of the
expected MSC_SERIAL. This commit addreses both issues.

3a61e97563 HID: logitech-hidpp: support combo keyboard touchpad TK820
The TK820 presents both a keyboard and a touchpad on the same
physical (and logical device). Use the generic hid-input
processing for the keyboard part. The keyboard input device is created
when the receiver is plugged in, so no events are missed on connect.

When the device actaully connects, we can set it to use the raw
multitouch reporting to have a consistent user experience accross
all Logitech touchpads.

c39e3d5fc9 HID: logitech-hidpp: late bind the input device on wireless connection
Now that the receiver forwards the connect/disconnect events, we can
know when the device is available to communicate with us.

When it is ready, we can for instance retrieve its full name, which
guarantee that we always have the same name for the DJ device (the DJ
name is somewhat shorter than the HID++ name).

This mechanism is mandatory for the touchpads line, which has the
min/max information stored in the device. This information can only
be retrieved when the device is connected. So we can not populate
the input device until we are sure that the device is connected.

This patch creates a new input device for such devices. However,
this input is not bound to hid directly, so the various drivers
which wants to use it are required to process completely the
incoming reports in .raw_event().

Note that the patch in itself just adds the bits for the next
ones, and this feature is disabled by default.

33797820af HID: logitech: allow the DJ device to request the unifying name
The names of the DJ devices are stored in the receiver. These names
can be retrieved through a HID++ command. However, the protocol says
that you have to ask the receiver for that, not the device iteself.

Introduce a special case in the DJ handling where a device can request
its unifying name, and when such a name is given, forward it also to
the corresponding device.

On the HID++ side, the receiver talks only HID++ 1.0, so we need to
implement this part of the protocol in the module.

925f0f3ed2 HID: logitech-dj: allow transfer of HID++ reports from/to the correct dj device
HID++ is a Logitech-specific protocol for communicating with HID
devices. DJ devices implement HID++, and so we can add the HID++
collection in the report descriptor and forward the incoming
reports from the receiver to the appropriate DJ device.

The same can be done in the other way, if someone calls a
.raw_request(), we can forward it to the correct dj device
by overriding the device_index in the HID++ report.

2f31c52529 HID: Introduce hidpp, a module to handle Logitech hid++ devices
Logitech devices use a vendor protocol to communicate various
information with the device. This protocol is called HID++,
and an exerpt can be found here:
https://drive.google.com/folderview?id=0BxbRzx7vEV7eWmgwazJ3NUFfQ28&usp=shar

The main difficulty which is related to this protocol is that
it is a synchronous protocol using the input reports.
So when we want to get some information from the device, we need
to wait for a matching input report.

This driver introduce this capabilities to be able to support
the multitouch mode of the Logitech Wireless Touchpad T651
(the bluetooth one). The multitouch data is available directly
from the mouse input reports, and we just need to query the device
on connect about its caracteristics.

HID++ and the touchpad features has a specific reporting mode
which uses pure HID++ reports, but Logitech told us not to use
it for this specific device. During QA, they detected that
some bluetooth input reports where lost, and so the only supported
mode is the pointer mode.

Several benefits here:
- we can drop the macro is_dj_device: I never been really conviced by

- we can simplify the hid driver logitech-djdevice, and make it aware

- we can use the Wireless PID of the DJ device as the product id of the
  hid device, this way the sysfs will differentiate between different
  DJ devices.

ea584595fc This is the bulk of GPIO changes for the v3.18 development

 - Increase the default ARCH_NR_GPIO from 256 to 512. This
   was done to avoid having a custom <asm/gpio.h> header for
   the x86 architecture - GPIO is custom and complicated
   enough as it is already! We want to move to a radix to
   store the descriptors going forward, and finally get rid
   of this fixed array size altogether.
 
 - Endgame patching of the gpio_remove() semantics initiated
   by Abdoulaye Berthe. It is not accepted by the system that
   the removal of a GPIO chip fails during e.g. reboot or
   shutdown, and therefore the return value has now painfully
   been refactored away. For special cases like GPIO expanders
   on a hot-pluggable bus like USB, we may later add some
   gpiochip_try_remove() call, but for the cases we have now,
   return values are moot.
 
 - Some incremental refactoring of the gpiolib core and ACPI
   GPIO library for more descriptor usage.
 
 - Refactor the chained IRQ handler set-up method to handle
   also threaded, nested interrupts and set up the parent IRQ
   correctly. Switch STMPE and TC3589x drivers to use this
   registration method.
 
 - Add a .irq_not_threaded flag to the struct gpio_chip, so
   that also GPIO expanders that block but are still not
   using threaded IRQ handlers.
 
 - New drivers for the ARM64 X-Gene SoC GPIO controller.
 
 - The syscon GPIO driver has been improved to handle the
   "DSP GPIO" found on the TI Keystone 2 SoC:s.
 
 - ADNP driver switched to use gpiolib irqchip helpers.

Unfortunatelly, the current code waits for an event of type UHID_GET_REPORT

Add 1 to UHID_GET_REPORT or UHID_SET_REPORT to actually wait for the
reply, and validate the reply.

7704ac9373 HID: wacom: implement generic HID handling for pen generic devices
ISDv4 and v5 are plain HID devices. We can directly implement a generic
HID parsing/handling and remove the need to manually add those PID in
the list of supported devices.

This patch implements the pen support only. The finger part will come in
a later patch.

To be properly notified of an .event() and a .report(), we need to force
hid-core to go through the HID parsing. By default, wacom.ko binds only
hidraw, so the hid parsing is not done by hid-core. When a true HID device
is there, we add the flag HID_CLAIMED_DRIVER to hid->claimed which will
force hid-core to parse the incoming reports.
(Note that this can be easily backported by directly setting the .claimed
flag to HID_CLAIMED_DRIVER even if hid-core does not support
HID_CONNECT_DRIVER)

2546dacd3e HID: wacom: split out input allocation and registration
If the input can be created earlier during probe, we can already populate
them while reading the report descriptor. This way, we can rely on the
hid subsystem directly for tablets which already provide a meaningful
report descriptor (like ISDv4-5).

This patch only splits the allocation and registration, but do not
change where we allocate the input. This will come in a later patch.

8ffffd5212 HID: wacom: fix timeout on probe for some wacoms
Some Wacom tablets (at least the ISDv4 found in the Lenovo X230) timeout
during probe while retrieving the input reports.
The only time this information is valuable is during the feature_mapping
stage, so we can ask for it there and discard the generic input reports
retrieval.

This gives a code path closer to the wacom.ko driver when it was in the
input subtree (not HID).

fb291cbd3f HID: sony: Corrections for the DualShock 4 HID descriptor
Fix a few minor issues in the HID descriptor:
 - A 6 bit entry had a logical maximum of 255 when the largest it can be is 63.
 - A logical max value was incorrectly being set to -1 instead of 255.
 - Set the min/max of the gyroscopes to -8192/8191 as that is the range of
   values which represent the true controller orientation.  Any values beyond
   those extents are just noise.

5b65c2a029 HID: rmi: check sanity of the incoming report
In the Dell XPS 13 9333, it appears that sometimes the bus get confused
and corrupts the incoming data. It fills the input report with the
sentinel value "ff". Synaptics told us that such behavior does not comes
from the touchpad itself, so we filter out such reports here.

Unfortunately, we can not simply discard the incoming data because they
may contain useful information. Most of the time, the misbehavior is
quite near the end of the report, so we can still use the valid part of
it.

12969e3bdc HID: wacom: make the WL connection friendly for the desktop
Currently, tablets connected to the WL receiver all share the same
VID/PID. There is no way for the user space to know which one is which
besides parsing the name. We can force the PID to be set to the
actual hardware. This way, the input device will have the correct PID
which can be match in libwacom.

With only this trick, the pad input does not inherit the ID_INPUT_TABLET
udev property from its parent. We can force udev to accept it by declaring
a BTN_STYLUS which is never used.

This way, tablets connected through WL can be used from the user point of
view in the same way they are used while connected through wire.
