1a3f83f649 HID: plantronics: fix errant mouse events
This version of the driver prevents Telephony pages which are not mapped as
Consumer Control applications AND are not on the Consumer Page from being
registered by the hid-input driver.

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.

9578f41aea HID: core: do not scan reports if the group is already set
This allows the transport layer (I have in mind hid-logitech-dj and uhid)
to set the group before it is added to the hid bus. This way, it can
bypass the hid_scan_report() call, and choose in advance which driver
will handle the newly created hid device.

c241c5eea8 HID: fix merge from wacom into the HID tree
While merging wacom from the input to the hid tree, some
comments have been duplicated. We can also integrate the
test for Synaptics devices in the switch case below, so
it is clear that there will be only one place for such

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)

ffe51d0d8a HID: add support for PenMount HID TouchScreen Driver
This patch adds a seperate hid-penmount driver to work
around an issue with the HID report descriptor. The
descriptor does not contain the ContactID usage and as
result the touchscreen is represented as normal mouse
to the system.

This driver maps the button 0 emitted by the touchscreen
to BTN_TOUCH. This makes it possible to use touch events
in userspace.

e19ff99f25 HID: rmi: only bind the hid-rmi driver to the mouse interface of composite USB devices
On composite HID devices there may be multiple HID devices on separate interfaces, but hid-rmi
should only bind to the mouse interface. One example is the Dell Venue 11 Pro's keyboard dock
which contains a composite USB device with a HID touchpad and HID keyboard on separate intefaces.
Since the USB Vendor ID is Synaptic's, hid-core is currently trying to bind hid-rmi to all\of
the HID devices. This patch ensures that hid-rmi only binds to the mouse interface.

29b4739134 Input: wacom - switch from an USB driver to a HID driver
All USB Wacom tablets are actually HID devices.
For historical reasons, they are handled as plain USB devices.
The current code makes more and more reference to the HID subsystem
like implementing its own HID report descriptor parser to handle new
devices.

From the user point of view, we can transparently switch from this state
to a driver handled in the HID subsystem and clean up a lot of USB specific
code in the wacom.ko driver.

The other benefit once the USB dependecies have been removed is that we can
use a tool like uhid to make regression tests and allow further cleanup or
new implementations without risking breaking current behaviors.

To match the current handling of devices in wacom_wac.c, we rely on the
hid_type set by usbhid. usbhid sets the hid_type to HID_TYPE_USBMOUSE when
it sees a USB boot mouse protocol declared and HID_TYPE_USBNONE when the
device is plain HID. There is thus a one to one matching between the list
of supported devices before and after the switch from USB to HID.

This breaks X and probably other userspace software.

and generating presses of a single button if it changes.  Also the missing

1b15d2e5b8 HID: core: fix validation of report id 0
Some drivers use the first HID report in the list instead of using an

19e4ec525b HID: core: fix computation of the report size
The extra seven bits are only required when allocating the report buffer.
We can not use those extra bytes for the length of the report in the
generic implementation of .request because the device might (will) refuse
the set_report command.
This has been verified on the Atmel touchpad found on the Samsung Ativ 9
plus, which uses hid-multitouch and HID over I2C. Without this fix, the
device refuses to switch to the multitouch mode, and it becomes unresponsive
from the user point of view.

Actually, this has been discussed during the initial submission of the
commit 4fa5a7f76c, see
https://patchwork.kernel.org/patch/3621751/

9fb6bf02e3 HID: rmi: introduce RMI driver for Synaptics touchpads
This driver add support for RMI4 over USB or I2C.
The current state is that it uses its own RMI4 implementation, but once
RMI4 is merged upstream, the driver will be a transport driver for the
RMI4 library.

Part of this driver should be considered as temporary. Most of the RMI4
processing and input handling will be deleted at some point.

I based my work on Andrew's regarding its port of RMI4 over HID (see
https://github.com/mightybigcar/synaptics-rmi4/tree/rmihid )
This repo presents how the driver may looks like at the end:
https://github.com/mightybigcar/synaptics-rmi4/blob/rmihid/drivers/input/rmi4/rmi_hid.c

Without this temporary solution, the workaround we gave to users
is to disable i2c-hid, which leads to disabling the touchscreen on the
XPS 11 and 12 (Haswell generation).

e24d0d399b HID: core: do not scan constant input report
The Microsoft Surface Type/Touch Cover 2 is a fancy device which advertised
itself as a multitouch device but with constant input reports.
This way, hid_scan_report() gives the group MULTITOUCH to it, but
hid-multitouch can not handle it due to the constant collection ignored
by hid-input.

To prevent such crap in the future, and while we do not fix this particular
device, make the scan_report coherent with hid-input.c, and ignore constant
input reports.

This USB composite device changes it product id dependent on if and which
keyboard cover is attached. Adding the covers to hid_have_special_driver
prevents loading the right hid drivers for the other two interfaces, all 3
get loaded with hid-microsoft. We don't even need hid-microsoft for the
keyboards. We have to revert this to load the right hid modules for each
interface.

e932d81786 HID: add hid-cp2112 driver
This patch adds support for the Silicon Labs CP2112 "Single-Chip HID USB to
SMBus Master Bridge."

This is a HID device driver which registers as an i2c adapter and gpiochip to
expose these functions of the CP2112. The customizable USB descriptor fields
are exposed as sysfs attributes.  The SMBus byte-read, byte-data-read/write,
and word-data-read transfer modes have been tested by talking to an i2c
sensor.  The GPIO functions and USB descriptor field programming have also
been tested.

95d50b6c5e HID: don't ignore eGalax/D-Wav/EETI HIDs
Certain devices with class HID, protocol None did not work with the HID
driver at one point, and as a result were bound to usbtouchscreen
instead as of commit 139ebe8 ("Input: usbtouchscreen - fix eGalax HID
ignoring").  This change was prompted by the following report:

https://lkml.org/lkml/2009/1/25/127

Unfortunately, the device mentioned in this report is no longer
available for testing.

We've recently discovered that some devices with class HID, protocol
None do not work with usbtouchscreen, but do work with usbhid.  Here is
the report that made this evident:

http://comments.gmane.org/gmane.linux.kernel.input/31710

Driver binding for these devices has flip-flopped a few times, so both
of the above reports were regressions.

This situation would appear to leave us with no easy way to bind every
device to the right driver.  However, in my own testing with several
devices I have not found a device with class HID that does not work with
the current HID driver.  It is my belief that changes to the HID driver
since the original report have likely fixed the issue(s) that made it
unsuitable at the time, and that we should prefer it over usbtouchscreen
for these devices.  In particular, HID quirks affecting these devices
were added/removed in the following commits since then:

fe6065d HID: add multi-input quirk for eGalax Touchcontroller
77933c3 Merge branch 'egalax' into for-linus
ebd11fe HID: Add quirk for eGalax touch controler.
d34c4aa HID: add no-get quirk for eGalax touch controller

This patch makes the HID driver no longer ignore eGalax/D-Wav/EETI
devices with class HID.  If there are in fact devices with class HID
that still do not work with the HID driver, we will see another round of
regressions.  In that case I propose we investigate why the device is
not working with the HID driver rather than re-introduce regressions for
functioning HID devices by again binding them to usbtouchscreen.

The corresponding change to usbtouchscreen will be made separately.

ad0e669b92 HID: Fix unit exponent parsing again
Revert some changes done in 7746383868.

Revert all changes done in hidinput_calc_abs_res as it mistakingly used
"Unit" item exponent nibbles to affect resolution value. This wasn't
breaking resolution calculation of relevant axes of any existing
devices, though, as they have only one dimension to their units and thus
1 in the corresponding nible.

Revert to reading "Unit Exponent" item value as a signed integer in
hid_parser_global to fix reading specification-complying values. This
fixes resolution calculation of devices complying to the HID standard,
including Huion, KYE, Waltop and UC-Logic graphics tablets which have
their report descriptors fixed by the drivers.

Explanations follow.

There are two "unit exponents" in HID specification and it is important
not to mix them. One is the global "Unit Exponent" item and another is
nibble values in the global "Unit" item. See 6.2.2.7 Global Items.

The "Unit Exponent" value is just a signed integer and is used to scale
the integer resolution unit values, so fractions can be expressed.

The nibbles of "Unit" value are used to select the unit system (nibble
0), and presence of a particular basic unit type in the unit formula and
its *exponent* (or power, nibbles 1-6). And yes, the latter is in two
complement and zero means absence of the unit type.

Taking the representation example of (integer) joules from the
specification:

[mass(grams)][length(centimeters)^2][time(seconds)^-2] * 10^-7

the "Unit Exponent" would be -7 (or 0xF9, if stored as a byte) and the
"Unit" value would be 0xE121, signifying:

Nibble  Part        Value   Meaning
-----   ----        -----   -------
0       System      1       SI Linear
1       Length      2       Centimeters^2
2       Mass        1       Grams
3       Time        -2      Seconds^-2

To give the resolution in e.g. hundredth of joules the "Unit Exponent"
item value should have been -9.

See also the examples of "Unit" values for some common units in the same
chapter.

However, there is a common misunderstanding about the "Unit Exponent"
value encoding, where it is assumed to be stored the same as nibbles in
"Unit" item. This is most likely due to the specification being a bit
vague and overloading the term "unit exponent". This also was and still
is proliferated by the official "HID Descriptor Tool", which makes this
mistake and stores "Unit Exponent" as such. This format is also
mentioned in books such as "USB Complete" and in Microsoft's hardware
design guides.

As a result many devices currently on the market use this encoding and
so the driver should support them.

f961bd3516 HID: detect Win 8 multitouch devices in core
Detecting Win 8 multitouch devices in core allows us to set quirks
before the device is parsed through hid_hw_start().
It also simplifies the detection of those devices in hid-multitouch and
makes the handling of those devices cleaner.

As Win 8 multitouch panels are in the group multitouch and rely on a
special feature to be detected, this patch adds a bitfield in the parser.

3dc8fc083d HID: Use hid_parser for pre-scanning the report descriptors
The Win 8 detection is sufficiently complex to warrant use of the full
parser code, in spite of the inferred memory usage. Therefore, we can use
the existing HID parser in hid-core for hid_scan_report() by re-using the
code from hid_open_report(). hid_parser_global, hid_parser_local and
hid_parser_reserved does not have any side effects. We just need to
reimplement the MAIN_ITEM callback to have a proper parsing without side
effects.

The driver currently only supports the Dual Arcade controller.
It fixes the negative axis event values (the devices sends -2) to match the
logical axis minimum of the HID report descriptor (the report announces -1).
It is needed because hid-input discards out of bounds values.

27ce405039 HID: fix data access in implement()
implement() is setting bytes in LE data stream. In case the data is not
aligned to 64bits, it reads past the allocated buffer. It doesn't really
change any value there (it's properly bitmasked), but in case that this
read past the boundary hits a page boundary, pagefault happens when
accessing 64bits of 'x' in implement(), and kernel oopses.

This happens much more often when numbered reports are in use, as the
initial 8bit skip in the buffer makes the whole process work on values
which are not aligned to 64bits.

This problem dates back to attempts in 2005 and 2006 to make implement()
and extract() as generic as possible, and even back then the problem
was realized by Adam Kroperlin, but falsely assumed to be impossible
to cause any harm:

  http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg47690.html

I have made several attempts at fixing it "on the spot" directly in
implement(), but the results were horrible; the special casing for processing
last 64bit chunk and switching to different math makes it unreadable mess.

I therefore took a path to allocate a few bytes more which will never make
it into final report, but are there as a cushion for all the 64bit math
operations happening in implement() and extract().

All callers of hid_output_report() are converted at the same time to allocate
the buffer by newly introduced hid_alloc_report_buf() helper.

Bruno noticed that the whole raw_size test can be dropped as well, as
hid_alloc_report_buf() makes sure that the buffer is always of a proper
size.

3685c18e17 HID: kye: Add report fixup for Genius Gila Gaming mouse
Genius Gila Gaming Mouse presents an obviously wrong report descriptor.
the Consumer control (report ID 3) is the following:
0x05, 0x0c,                    // Usage Page (Consumer Devices)       105

0x2a, 0xff, 0x7f,              //   Usage Maximum (32767)             115
0x15, 0x00,                    //   Logical Minimum (0)               118
0x26, 0xff, 0x7f,              //   Logical Maximum (32767)           120
0x75, 0x10,                    //   Report Size (16)                  123
0x95, 0x03,                    //   Report Count (3)                  125
0x81, 0x00,                    //   Input (Data,Arr,Abs)              127
0x75, 0x08,                    //   Report Size (8)                   129
0x95, 0x01,                    //   Report Count (1)                  131
0x81, 0x01,                    //   Input (Cnst,Arr,Abs)              133
0xc0,                          // End Collection                      135

So the first input whithin this report has a count of 3 but a usage range
of 32768. So this value is obviously wrong as it should not be greater than
the report count.

b1a1442a23 HID: core: fix reporting of raw events
hdrw->raw event can return three different return value types:

- ret < 0	indicates that the hdrv driver found an error while parsing
- ret == 0	indicates no error has been encountered, and the driver has
          	processed the report
- ret > 0	indicates that there was no parsing error, and the driver hasn't
		processed the event.

Calling hid_report_raw_event() has to be called appropriately so that it
reflects what has been done by ->raw_event() callback, otherwise we might
updates of the in-kernel structure are lost upon arrival of the report, which
is wrong.

d23efc1947 HID: add driver for ELO 4000/4500
This is a driver for ELO 4000/4500 devices which report themselves as
HID devices, but do not really send HID events on touch. So we
introduce a new HID 'quirk' driver with a raw_event handler where we
take care of those events.

What we need additionally is an input_configured hook, because the
device does not mention anything about PRESSURE and TOUCH in its
report descriptor, but it actually generate those. So we set the bits
in the corresponding input_dev in that hook.

Thanks to Petr Ostadal who was willing to test the driver. The rest of
Cc's listed below had something to do with that driver over the years
in our enterprise tree.

interface.
On those devices, the USB audio interface is working nicely,
but the HID interface is not working with the kernel usbhid driver,
and it requires a specific userspace program.
We could unbind it from userspace but just attaching the usbhid driver has
sometimes nasty effects:
either confusing the device state machine or triggering a storm of volume key
events making eventual sound UI blinking like crazy.

1deb9d341d HID: debug: fix RCU preemption issue
Commit 2353f2bea ("HID: protect hid_debug_list") introduced mutex
locking around debug_list access to prevent SMP races when debugfs
nodes are being operated upon by multiple userspace processess.

mutex is not a proper synchronization primitive though, as the hid-debug
callbacks are being called from atomic contexts.

We also have to be careful about disabling IRQs when taking the lock
to prevent deadlock against IRQ handlers.

Benjamin reports this has also been reported in RH bugzilla as bug #958935.

More recent versions of the IR receiver are also supported through
a patch by Alex Karpenko. The patch also adds support for the 2nd

c849a6143b HID: Separate struct hid_device's driver_lock into two locks.
This patch separates struct hid_device's driver_lock into two. The
goal is to allow hid device drivers to receive input during their
probe() or remove() function calls. This is necessary because some
drivers need to communicate with the device to determine parameters
needed during probe (e.g., size of a multi-touch surface), and if
possible, may perfer to communicate with a device on host-initiated
disconnect (e.g., to put it into a low-power state).

Historically, three functions used driver_lock:

- hid_device_probe: blocks to acquire lock
- hid_device_remove: blocks to acquire lock
- hid_input_report: if locked returns -EBUSY, else acquires lock

This patch adds another lock (driver_input_lock) which is used to
block input from occurring. The lock behavior is now:

- hid_device_probe: blocks to acq. driver_lock, then driver_input_lock
- hid_device_remove: blocks to acq. driver_lock, then driver_input_lock
- hid_input_report: if driver_input_lock locked returns -EBUSY, else
  acquires driver_input_lock

This patch also adds two helper functions to be called during probe()
or remove(): hid_device_io_start() and hid_device_io_stop(). These
functions lock and unlock, respectively, driver_input_lock; they also
make a note of whether they did so that hid-core knows if a driver has
changed the lock state.

This patch results in no behavior change for existing devices and
drivers. However, during a probe() or remove() function call in a
driver, that driver may now selectively call hid_device_io_start() to
let input events come through, then optionally call
hid_device_io_stop() to stop them.

30ba2fbde1 HID: add ThingM blink(1) USB RGB LED support
The ThingM blink(1) is an open source hardware USB RGB LED. It contains
an internal EEPROM, allowing to configure up to 12 light patterns. A
light pattern is a RGB color plus a fade time. This driver registers a
LED class instance with additional sysfs attributes to support basic
functions such as setting RGB colors, fade and playing. Other functions
are still accessible through the hidraw interface.

At this time, the only documentation for the device is the firmware
source code from ThingM, plus a few schematics. They are available at:

https://github.com/todbot/blink1

This patch is version 3. It updates the name of the source file, the
driver and the led sysfs entry, according to comments from Jiri Kosina
and Simon Wood.

a464918419 HID: add support for Sony RF receiver with USB product id 0x0374
Some Vaio desktop computers, among them the VGC-LN51JGB multimedia PC, have
a RF receiver, multi-interface USB device 054c:0374, that is used to connect
a wireless keyboard and a wireless mouse.

The keyboard works flawlessly, but the mouse (VGP-WMS3 in my case) does not
seem to be generating any pointer events. The problem is that the mouse pointer
is wrongly declared as a constant non-data variable in the report descriptor
(see lsusb and usbhid-dump output below), with the consequence that it is
ignored by the HID code.

Add this device to the have-special-driver list and fix up the report
descriptor in the Sony-specific driver which happens to already have a fixup
for a similar firmware bug.

4529eefad0 HID: hidp: fallback to input session properly if hid is blacklisted
This patch against kernel 3.7.0-rc8 fixes a kernel oops when turning on the
bluetooth mouse with id 0458:0058 [1].

The mouse in question supports both input and hid sessions, however it is
blacklisted in drivers/hid/hid-core.c so the input session is one that should
be used. Long ago (around kernel 3.0.0) some changes in the bluetooth
subsystem made the kernel do not fallback to input session when hid session is
not supported or blacklisted. This patch restore that behaviour by making the
kernel try the input session if hid_add_device returns ENODEV.

The patch exports hid_ignore() from hid-core.c so that it can be used in the
bluetooth subsystem.

f9af7b9edc HID: Add Apple wireless keyboard 2011 ANSI to special driver list
Commit 0a97e1e9f9 ('HID: apple: Add Apple wireless keyboard 2011 ANSI PID')
did not update the special driver list in hid-core.c, so hid-generic may
still bind to this device.

f262d1fa2c HID: add usage_index in struct hid_usage.
Currently, there is no way to know the index of the current field
in the .input_mapping and .event callbacks  when this field is inside
an array of HID fields.
This patch adds this index to the struct hid_usage so that this
information is available to input_mapping and event callbacks.

729b814ace HID: Ignore D-WAV/eGalax devices handled by usbtouchscreen
Previously, both usbhid and usbtouchscreen would bind to D-WAV devices
with class HID and protocol None, so they would be claimed by whichever
driver was loaded first.  Some of these devices do in fact work with
usbhid, but not all of them do.  OTOH they all work with usbtouchscreen
as of commit 037a833ed0 ("Input:
usbtouchscreen - initialize eGalax devices").  So we ignore them in
usbhid to prevent getting in the way of usbtouchscreen and claiming an
interface that we may not be able to do anything useful with.

4ddfe0289b HID: Add driver for ION iCade
Add a driver for the ION iCade mini arcade cabinet [1]. The device generates a
key press and release for each joystick movement or button press or release.
For example, moving the stick to the left will generate the "A" key being
pressed and then released.

A list of all the combinations is available in the iCade developer guide [2].

This driver hides all this and makes the device work as a generic joystick.

def7cb8cd4 Staging tree update for 3.7-rc1
Here is the big staging tree update for the 3.7-rc1 merge window.
 
 There are a few patches in here that are outside of the staging area,
 namely HID and IIO patches, but all of them have been acked by the
 relevant subsystem maintainers.  The IIO stuff is still coming in
 through this tree as it hasn't entirely moved out of the staging tree,
 but is almost there.
 
 Other than that, there wa a ton of work on the comedi drivers to make
 them more readable and the correct style.  Doing that removed a lot of
 code, but we added a new driver to the staging tree, so we didn't end up
 with a net reduction this time around:
  662 files changed, 51649 insertions(+), 26582 deletions(-)

5844c1cdb6 HID: Add support for Sony PS3 BD Remote Control
The Sony PS3 Blue-ray Disc Remote Control used to be supported by the
BlueZ project's user space, but the code that handled it was recently
removed as its functionality conflicted with a real HSP implementation
and the mapping was thought to be better handled in the kernel. This is
a port of the mapping logic from the fakehid driver by Marcel Holtmann
to the in-kernel HID layer.

We also add support for the Logitech Harmony Adapter for PS3, which
emulates the BD Remote.

86e6b77eb7 HID: keep dev_rdesc unmodified and use it for comparisons
The dev_rdesc member of the hid_device structure is meant to store the original
report descriptor received from the device, but it is currently passed to any
report_fixup method before it is copied to the rdesc member. This patch uses a
temporary buffer to shield dev_rdesc from the side effects of many HID drivers'
report_fixup implementations.

usbhid's hid_post_reset checks the report descriptor currently returned by the
device against a descriptor that may have been modified by a driver's
report_fixup method. That leaves some devices nonfunctional after a resume, with
a "reset_resume error 1" reported. This patch checks the new descriptor against
the unmodified dev_rdesc instead and uses the original, instead of modified,
report size.

23408f95fa HID: Bump maximum global item tag report size to 128 bytes
The Freescale i.MX28 BootROM USB recovery mode implements the USB HID
protocol, yet the global item tag report size is 128. Linux checks if
this is 96 as of now, see [1]. This causes Linux to refuse to communicate
with this device, making it impossible to use the recovery mode.

This is not a standard HID device per se, but rather a software emulation
implemented within the BootROM code and realized through USB OTG-capable
port switched to device mode present on the device.

Previous attempt to discuss this issue dates back to 2011, see [2]. There
has been not much response. Also noteworthy is the [3], where there seems
to be a pointing device that has issue similar to this one.

The tool making use of the USB recovery mode is available at [4].
