Chris Schlund 8ef3953108 HID: hid-lcpower: fix key mapping
I already got some feedback for this module, telling me red and blue keys are
exchanged.  I checked it, and they are right. Due to my incorrect userspace
settings I missed this during my testing.

Alan Ott b4dbde9da8 HID: Add Support for Setting and Getting Feature Reports from hidraw
Per the HID Specification, Feature reports must be sent and received on
the Configuration endpoint (EP 0) through the Set_Report/Get_Report
interfaces.  This patch adds two ioctls to hidraw to set and get feature
reports to and from the device.  Modifications were made to hidraw and
usbhid.

New hidraw ioctls:
  HIDIOCSFEATURE - Perform a Set_Report transfer of a Feature report.
  HIDIOCGFEATURE - Perform a Get_Report transfer of a Feature report.

The safest quirk for a device (the one that works out of the box for

make any assumption on the device. When adding a new device, we can
easily test it against MT_CLS_DEFAULT, and then optimize it with other
quirks: that's why no device use MT_CLS_DEFAULT right now.

David Rientjes 6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

Melchior FRANZ 73bc7d315f USB: add support for Dream Cheeky DL100B Webmail Notifier (1d34:0004)
So far the USBLED driver only supports Delcom's "USB Visual Signal
Indicator" (http://www.delcomproducts.com/products_USBLMP.asp). The
driver generates virtual files "red", "green", and "blue" under the
device's /sys/ directory, where color values can be read from and
written to.

This patch adds support for Dream Cheeky's "DL100B Webmail Notifier"
(http://www.dreamcheeky.com/webmail-notifier -- available from several
shops, such as http://www.conrad.at/ce/de/product/777048/USB-WEBMAIL).
This device isn't as pretty as Delcom's, but it's *far* cheaper, and
its 3 LEDs can be set in 32 brightness steps each. The grey envelope
contour can easily be removed, leaving a rather neutral white box (with
a few small holes), which is useful for generic signalling purposes.
Of course, the small circuit board can easily be put into a prettier
case.

The DL100B device pretends to be a HID, but the HID descriptor shows
that it's not overly useful as such (see below). The patch therefore
removes the "HID-ness" (hid-core.c, hid-ids.h), and adds the necessary
commands to usbled.c. The protocol info comes from the developer's
manual that Dream Cheeky kindly provided (815DeveloperManual.pdf).

the absense of any indication of a touch frame. This patch converts
the driver to the MT slots protocol, and outputs one full touch frame

The drivers using the type B protocol all report tracking information
the same way. The contact id is semantically equivalent to
ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates
the driver. The situation can be improved upon by providing a common
pointer emulation code, thereby removing the need for the tracking id
in the driver.  This patch moves all tracking event handling over to
the input core, simplifying both the existing drivers and the ones
currently in preparation.

Benjamin Tissoires ad6d426702 HID: hid-mosart: ignore buttons report
This commit allows the device to be recognized as a touchscreen, and not a
touchpad by xf86-input-evdev.

The device has 2 modes. The first one is an emulation of a touchscreen by
sending left and right button, and the second mode is the one used in
dual-touch (sending trackingID, touch and else).

That's why there is a hid report containing left and right buttons
(9000001 and 9000002). The point is that xorg relies on these fields to
determine if it's a touchpad or a touchscreen.
Clearing the report (return -1) makes xorg detecting it out of the box
as a quite pleasant (dual)touchscreen.

be fine in the normal mode, but the driver puts the device in multitouch
mode where no relative events are generated. Also, userspace software
depends on accurate axis information for device type detection. Thus,
ignoring the relative axes from the Magic Trackpad is best.

Valentine Barshak 1a8e8fab79 HID: Fix race between disconnect and hiddev_ioctl
A USB HID device can be disconnected at any time.
If this happens right before or while hiddev_ioctl is in progress,
the hiddev_ioctl tries to access invalid hiddev->hid pointer.
When the hid device is disconnected, the hiddev_disconnect()
ends up with a call to hid_device_release() which frees
hid_device, but doesn't set the hiddev->hid pointer to NULL.
If the deallocated memory region has been re-used by the kernel,
this can cause a crash or memory corruption.

Since disconnect can happen at any time, we can't initialize
struct hid_device *hid = hiddev->hid at the beginning of ioctl
and then use it.

This change checks hiddev->exist flag while holding
the existancelock and uses hid_device only if it exists.

Arnd Bergmann 6038f373a3 llseek: automatically add .llseek fop
All file_operations should get a .llseek operation so we can make
nonseekable_open the default for future file operations without a
.llseek pointer.

The three cases that we can automatically detect are no_llseek, seq_lseek
and default_llseek. For cases where we can we can automatically prove that
the file offset is always ignored, we use noop_llseek, which maintains
the current behavior of not returning an error from a seek.

New drivers should normally not use noop_llseek but instead use no_llseek
and call nonseekable_open at open time.  Existing drivers can be converted
to do the same when the maintainer knows for certain that no user code
relies on calling seek on the device file.

The generated code is often incorrectly indented and right now contains
comments that clarify for each added line why a specific variant was
chosen. In the version that gets submitted upstream, the comments will
be gone and I will manually fix the indentation, because there does not
seem to be a way to do that using coccinelle.

Some amount of new code is currently sitting in linux-next that should get
the same modifications, which I will do at the end of the merge window.

Many thanks to Julia Lawall for helping me learn to write a semantic
patch that does all this.

Philipp Merkel f51661105c HID: Fix for problems with eGalax/DWAV multi-touch-screen
This patch fixes three problems with the eGalax/DWAV multi-touch
screen found in the Eee PC T101MT:

1) While there is a dedicated multitouch driver for the screen
   (hid-egalax.c), the MULTI_INPUT quirk is also applied, preventing
   the hid-egalax driver from working. This patch removes the quirk
   so the hid-egalax driver can handle the device correctly.
2) The x and y coordinates sent by the screen in multi-touch mode are
   shifted by three bits from the events sent in single-touch mode, thus
   the coordinates are out of range, leading to the pointer being stuck
   in the bottom-right corner if no additional calibration is applied
   (e.g. in the X evdev driver). This patch shifts the coordinates back.
   This does not decrease accuracy as the last three bits of the "wrong"
   coordinates are always 0.
3) Only multi-touch pressure events are sent, single touch emulation is
   missing pressure information. This patch adds single-touch
   ABS_PRESSURE events.

Alan Ott fe2c91ee24 HID: don't Send Feature Reports on Interrupt Endpoint
Feature reports should only be sent on the control endpoint.

The USB HID standard is unclear and confusing on this issue. It seems to
suggest that Feature reports can be sent on a HID device's Interrupt OUT
endpoint.  This cannot be the case because the report type is not encoded in
transfers sent out the Interrput OUT endpoint.  If Feature reports were sent on
the Interrupt OUT endpint, they would be indistinguishable from Output reports
in the case where Report IDs were not used.

Further, Windows and Mac OS X do not send Feature reports out the interrupt OUT
Endpoint.  They will only go out the Control Endpoint.

In addition, many devices simply do not hande Feature reports sent out the
Interrupt OUT endpoint.

Dmitry Torokhov f5854fad39 Input: hid-input - allow mapping unknown usages
Currently HID layer only allows to remap keycodes for known usages,
and responds with -EINVAL when user tries to map new usage code.
This precludes us form relying on udev/keymap for establishing correct
mappings and forces us to write dummy HID drivers responsible only for
setting up keymaps.

Let's allow remapping not only usages that have been set up as keys
(usage->type == EV_KEY) but also yet-unmapped usages (usage->type == 0).

Guillaume Chazarain 8fe294caf8 HID: fix hiddev's use of usb_find_interface
My macbook infrared remote control was broken by commit
bd25f4dd69 ("HID: hiddev: use
usb_find_interface, get rid of BKL").

This device appears in dmesg as:
apple 0003:05AC:8242.0001: hiddev0,hidraw0: USB HID v1.11 Device
[Apple Computer, Inc. IR Receiver] on usb-0000:00:1d.2-1/input0

It stopped working as lircd was getting ENODEV when opening /dev/usb/hiddev0.

AFAICS hiddev_driver is a dummy driver so usb_find_interface(&hiddev_driver)
does not find anything.

The device is associated with the usbhid driver, so let's do
usb_find_interface(&hid_driver) instead.

Chase Douglas a462230e16 HID: magicmouse: enable Magic Trackpad support
The trackpad speaks a similar, but different, protocol from the magic
mouse. However, only small code tweaks here and there are needed to make
basic multitouch work.

Extra logic is required for single-touch emulation of the touchpad. The
changes made here take the approach that only one finger may emulate the
single pointer when multiple fingers have touched the screen. Once that
finger is raised, all touches must be raised before any further single
touch events can be sent.

Sometimes the magic trackpad sends two distinct touch reports as one big
report. Simply splitting the packet in two and resending them through
magicmouse_raw_event ensures they are handled properly.

I also added myself to the copyright statement.

Nikolai Kondrashov 67168fd7d4 HID: rdesc parser: remove local item size limit
The HID report descriptor parser requires local items, except "delimiters",
to have data. I.e. to have non-zero size. This removes the restriction.

The HID specification doesn't seem to have such restriction and, for
example, a "usage" item could have zero size if the usage ID is zero.
At least one usage page - Keyboard/Keypad lists zero ID as valid.

This doesn't seem to happen in the wild, probably because the official tool
for authoring report descriptors always puts data even for zero values for
some items, including "usage" items.

However, this makes little sense and at least one open source tool for
descriptor authoring generates zero data size "usage" items, which saves
some space, especially if many such items are used in a descriptor.

at device disconnect time, such as

This patch selects a compromise usage - "Tablet Pick" (0x46) to be mapped to
BTN_STYLUS2. Some tablets use "Eraser" usage, but mapping it to a button
wouldn't be entirely correct, because the specification says it may be "a

Arnd Bergmann bd25f4dd69 HID: hiddev: use usb_find_interface, get rid of BKL
This removes the private hiddev_table in the usbhid
driver and changes it to use usb_find_interface
instead.

The advantage is that we can avoid the race between
usb_register_dev and usb_open and no longer need the
big kernel lock.

This doesn't introduce race condition -- the intf pointer could be
invalidated only in hiddev_disconnect() through usb_deregister_dev(),
but that will block on minor_rwsem and not actually remove the device
until usb_open().

Bruno Prémont 365f1fcd0d HID: picolcd: do not reallocate memory on depth change
Reallocating memory in depth change does not work well if some
userspace application has mmapped() the framebuffer as that mapping
does not get adjusted (thus application continues to write to old
buffer).
In addition doing deferred_io_cleanup() and init() inside of set_par()
tends to deadlock with fbcon's flashing cursor.

Avoid all this by allocating a buffer that can hold 8bpp framebuffer
and just use 1/8 of it while running at 1bpp.

Chase Douglas 0b778e76c1 HID: magicmouse: add param for scroll speed
The new scroll_speed param takes an integer value from 0 to 63, where 0
is slowest and 63 is fastest. The default of 32 remains the same. This
parameter also affects scroll acceleration linearly.

A second part of this change is a tightly coupled modification to the
scroll acceleration. Previously, scroll acceleration could be reset
without lifting the scroll finger. This is rather unintuitive and hard
to control in the case where a user wants faster scrolling, but wants to
hold the scroll touch for longer than a moment.

Note that scroll acceleration levels are now 1-7, where 7 is slowest. In
the previous implementation, there were 8 levels defined, but it was
impossible to start at the slowest level. In order to keep the default
scroll speed unchanged, only 7 levels are used now.

user supplied ignore flags are not. Thus, the IGNORE quirk (0x0004)

HID_QUIRK_NO_IGNORE still takes precedence over HID_QUIRK_IGNORE.

Stefan Achatz 206f5f2fcb HID: roccat: propagate special events of roccat hardware to userspace
Module roccat is a char device used to report special events of roccat hardware
to userland. These events include requests for on-screen-display of profile or
dpi settings or requests for execution of macro sequences that are not stored
in device. The information in these events depends on hid device implementation
and contains data that is not available in a single hid event or else hidraw
could have been used.

It is inspired by hidraw, but uses only one circular buffer for all readers.
The device is as generic as possible so that the functionality is usable by all
(kone and upcomming) roccat device drivers.

Jiri Kosina 73d5e8f77e HID: fix up 'EMBEDDED' mess in Kconfig
The whole point of making some of the drivers automatically selected
unless 'EMBEDDED' was to handle quirks transparently after their separation
from the generic core.

Over time, some of the later-added quirks grew into more standalone drivers,
implementing non-trivial features a being larger than a few bytes of code.

In addition to that, some of the standalone drivers don't make sense for
99.9% of the users, as they are very specific to rare devices.

Therefore build by default in only those drivers which

- we historically used to support even before quirk separation from the
  core code
- are isolated enough and likely to hit quite large portion of the
  users anyway (Microsoft, Logitech)

Alan Stern 0ede76fcec USB: remove uses of URB_NO_SETUP_DMA_MAP
This patch (as1350) removes all usages of coherent buffers for USB
control-request setup-packet buffers.  There's no good reason to
reserve coherent memory for these things; control requests are hardly
ever used in large quantity (the major exception is firmware
transfers, and they aren't time-critical).  Furthermore, only seven
drivers used it.  We might as well always use streaming DMA mappings
for setup-packet buffers, and remove some extra complexity from
usbcore.

The DMA-mapping portion of hcd.c is currently in flux.  A separate
patch will be submitted to remove support for URB_NO_SETUP_DMA_MAP
after everything else settles down.  The removal should go smoothly,
as by then nobody will be using it.

Alan Ott a8ab5d58b0 HID: hidraw: Use Interrupt Endpoint for OUT Transfers if Available
This patch makes the hidraw driver use the first Interrupt OUT endpoint for
HID transfers to the device if such an endpoint exists. This is consistent
with the behavior of the hiddev driver, and the logic is similar.

From the USB HID specification:

   The Interrupt Out pipe is optional. If a device declares an Interrupt Out
   endpoint then Output reports are transmitted by the host to the device
   through the Interrupt Out endpoint. If no Interrupt Out endpoint is
   declared then Output reports are transmitted to a device through the
   Control endpoint, using Set_Report(Output) requests.

Jiri Kosina 23d021167e HID: magicmouse: fix input registration
When HIDRAW is not set, hid_hw_start() returns ENODEV as no subsystem has
claimed the magicmouse device, and probe routine bails out. Which is not what we want.

This happens because magicmouse driver is instantiating the connection to
Input subsystem itself, and since commit 28918c211d ("HID: magicmouse: fix
oops after device removal") the HID core is not registering input device
itself.

Fix this by letting HID core register the input device (so that hid_hw_start()
succeeds, as the device is claimed by at least one subsystem) and de-register
it again later before proceeding with proper input setup.

Rafi Rubin 369db2a600 HID: ntrig: add sensitivity and responsiveness support
The old rejection size thresholds were too high for the 12" devices.
Larger surfaces like the Dell Studio17 exacerbated the problem since
contact size is reported on the same logical scale, making a contact
look smaller to the larger screen.

Since we have observed erroneous ghost events from these devices we
still need to filter the incoming stream.

The prior size threshold filter is still in place, though with
defaults set to leave it off.

This patch adds the two new classes of filters, those that reject
live frames before activation, and those that reject empty frames
until deactivation.  These filters are expressed in terms of a
simple state machine for clarity (I hope).

The activation filter has two components, slack and size, events
are discarded until either is satisfied.  Slack is defined as
the number of seemingly good contacts to read before accepting the
stream as valid (if the threshold is reached in the middle of a frame
the remainder of that frame is still discarded).

The deactivation filter discards empty frames until hitting a
deactivate slack.  This time measured in frames.  N-Trig devices
emit 5-8 (observed so far) empty frames at the end of multitouch
activity.  Ignoring the first few enables us to safely and gracefully
handle erroneous empty frames, thus preventing a change in the tool
state which would otherwise result in things like broken lines or
dragged objects being dropped in bad places.

Also, now that devices with different logical densities have
been observed, the aforementioned sizes are scaled from physical
to logical scales once those scales are identified.  Hopefully this
should mean that a given threshold value means the same thing across
differing devices.
