hidinput_calc_abs_res should return the closest int in the division
instead of the floor.
On a device with a logical_max of 3008 and a physical_max of 255mm,
previous implementation gave a resolution of 11 instead of 12.
With 11, user-space computes a physical size of 273.5mm and the
round_closest results gives 250.6mm.
The old implementation introduced an error of 2cm in this example.

Button names for USB gamepads are currently assigned incorrectly, as the evdev
code assigned to buttons is "BTN_GAMEPAD + code", which on devices with more
then 16 buttons bleeds over into button names reserved for graphic tablets
(BTN_TOOL_PEN, etc.). This causes problems further down the line as the device
are now no longer detected as joystick. This patch fixes that by assigning
buttons outside the range to BTN_TRIGGER_HAPPY (as is already the case for USB
joysticks).
Furthermore this patch corrects the assignment to BTN_TRIGGER_HAPPY, as
currently the first button over 16 is assigned to BTN_TRIGGER_HAPPY17 (i.e.
BTN_TRIGGER_HAPPY+0x10) not BTN_TRIGGER_HAPPY.

Switch the driver over to device group handling. By adding the

can be removed. Since all HID MT devices have HID_DG_CONTACTID, they
can be removed from the hid_have_special_driver list.

I've sent an email earlier asking for help with a GetFeature code, and now I
have a second patch on top of Jeremy's to provide the battery functionality
for devices that support reporting it.
If I understood correctly when talking to Jeremy he said his device
never actually reported the status as an input event (sorry if I didn't
understand it correctly), and after reading HID specs I believe it's
really because it was meant to be probed, I have an Apple Keyboard and
Magic Trackpad both bluetooth batteries operated, so using PacketLogger
I saw that Mac OSX always ask the battery status using the so called
GetFeature.
What my patch does is basically:
- store the report id that matches the battery_strength
- setup the battery if 0x6.0x20 is found, even if that is reported as a feature
(as it was meant to be but only the MagicTrackpad does)
- when upower or someone access /sys/class/power_supply/hid-*/capacity it
will probe the device and return it's status.
It works great for both devices, but I have two concerns:
- the report_features function has a duplicated code
- it would be nice if it was possible for specific drivers to provide their own
probe as there might be some strange devices... (but maybe it's
already possible)
I've talked to the upower dev and he fixed it to be able to show the
right percentage.
Here how the uevent file (in /sys/class/power_supply/hid-*/) looks like:
POWER_SUPPLY_NAME=hid-00:22:41:D9:18:E7-battery
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_ONLINE=1

Some HID devices, such as my Bluetooth mouse, report their battery
strength as an event. Rather than passing it through as a strange
absolute input event, this patch registers it with the power_supply
subsystem as a battery, so that the device's Battery Strength can be
reported to usermode.
The battery appears in sysfs names
/sys/class/power_supply/hid-<UNIQ>-battery, and it is a child of the
battery-containing device, so it should be clear what it's the battery of.
Unfortunately on my current Fedora 16 system, while the battery does
appear in the UI, it is listed as a Laptop Battery with 0% charge (since
it ignores the "capacity" property of the battery and instead computes
it from the "energy*" fields, which we can't supply given the limited
information contained within the HID Report).
Still, this patch is the first step.

HID 1.11 specification, section 5.10 tells us:
HID class devices support the ability to ignore selected fields in a
report at run- time. This is accomplished by declaring bit field in a
report that is capable of containing a range of values larger than
those actually generated by the control. If the host or the device
receives an out-of-range value then the current value for the
respective control will not be modified.
So we shouldn't be restricted to EV_ABS only.

I've got a Tivo Slide bluetooth remote/dongle, which uses a fair number
of hid usages that aren't currently mapped in hid-input.c. I'd initially
written additions to hid-input.c with just this device in mind,
including some bits that were specific to the device. This go around,
I'm looking at adding/correcting as many generic HID usages from the HID
Usage Tables, version 1.12, as I can -- which also serves to enable all
but four of the buttons on the Tivo Slide remote[*].
Outside of fixing the obviously incorrect mapping of 0xc 0x45 from
KEY_RADIO to KEY_RIGHT, and making use of the new KEY_IMAGES (just added
in 2.6.39-rc4) for AL Image Browser instead of KEY_MEDIA, these are
purely additions, and thus should have no negative impact on any already
functional HID devices. Most of the added mappings seemed to be
perfectly logical to me, but there were a few that were mapped on more
of an "I think this makes the most sense" basis.
[*] I'll handle the last four tivo buttons via an hid-tivo.c follow-up.

It is a little bit inconvenient for people who have some non-standard
HID hardware (usually violating the HID specification) to have to
recompile kernel with CONFIG_HID_DEBUG to be able to see kernel's perspective
of the HID report descriptor and observe the parsed events. Plus the messages
are then mixed up inconveniently with the rest of the dmesg stuff.
This patch implements /sys/kernel/debug/hid/<device>/rdesc file, which
represents the kernel's view of report descriptor (both the raw report
descriptor data and parsed contents).
With all the device-specific debug data being available through debugfs, there
is no need for keeping CONFIG_HID_DEBUG, as the 'debug' parameter to the
hid module will now only output only driver-specific debugging options, which has
absolutely minimal memory footprint, just a few error messages and one global
flag (hid_debug).
We use the current set of output formatting functions. The ones that need to be
used both for one-shot rdesc seq_file and also for continuous flow of data
(individual reports, as being sent by the device) distinguish according to the
passed seq_file parameter, and if it is NULL, it still output to kernel ringbuffer,
otherwise the corresponding seq_file is used for output.
The format of the output is preserved.

Since 2.6.25 the HID_QUIRK_APPLE_HAS_FN quirk is enabled even for
non-laptop Apple keyboards of the Aluminium series. The USB version of
these don't need Numlock emulation, like the laptop (and Aluminium
Wireless) do, as they have a proper keypad.
This patch splits the Numlock emulation for Apple keyboards in a
different quirk flag, so that it can be enabled for all the keyboards
but the Aluminium USB ones.
If the Numlock emulation is enabled for Aluminium USB keyboards, the
JKL and UIO keys become the numeric pad, and the rest of the keyboard
is disabled, included the key used to disable Numlock.
Additionally, these keyboard should not have a Numlock at all, as the
Numlock key is instead replaced by the 'Clear' key as usual for Apple
USB keyboards.

F5 and F6 have no second function printed on them. Thus their definitions have
been removed from the table.
KEY_CYCLEWINDOWS doesn't name the function of Mac OS X' Expose properly and
because we couldn't find a better key code, we decided to use KEY_FN_F4
instead.
We also changed KEY_BACK and KEY_FORWARD, which apply to browser functions, to
KEY_PREVIOUSSONG and KEY_NEXTSONG, since the keys are intended to control a
music player.

The old code (before move) stopped further processing of the
event after it has been already processed by the quirk handler.
The new code didn't propagate the return value properly, and
therefore the processing always proceeded, which was wrong.
This patch fixes it. Pointed out in kernel.org bugzilla #9842

This patch separates also the hid-input quirks that have to be
applied at the time the event occurs, so that the generic code
handling HUT-compliant devices is not messed up by them too much.

Currently, the handling of mapping between hid and input for devices
that don't conform to HUT 1.12 specification is very messy -- no per-device
handling, no blacklists, conditions on idVendor and idProduct placed
all over the code.
This patch moves all the device-specific input mapping to a separate
file, and introduces a blacklist-style handling for non-standard
device-specific mappings.

Genius KB-29E has broken report descriptor, which causes some of the
Consumer usages to appear incorrectly as Button usages. We fix it by
fixing the report descriptor before it is being parsed.
Also a few of the keys violate the HUT standard, so they need a special
handling. They currently fall into "Reserved" range as per HUT 1.12.

This mouse distinguishes horizontal wheel from vertical by a special "pseudo
event" GenericDesktop.00b8, with values of 0 for vertical and 8 for horizontal
wheel. Because this event is supplied by the parser too late, we need to delay
a wheel event, wait for this one and send either REL_WHEEL or REL_HWHEEL to
input depending on the event value.

The MS Presenter 8000 bluetooth mouse is a "dual-use" device: If you
press a button on the top, you can turn it around and find special keys
on the other side, useful for presentations. This patch maps those three
bottom-keys that are not already detected to the intended functions. The
magic bottom on the top is mapped to F5 when we switch from mouse to
presenter mode in order to activate the presentation mode in the related
software (e.g. OpenOffice).

The infrared remote receiver found in the SantaRosa MacBookPro
laptops (MacBookPro3,1) need to be forced to expose a HIDDEV
interface (instead of HIDINPUT) so that lirc can access it using
the 'macmini' driver.
The patch below adds the required quirk for forcing the HIDDEV
interface to be activated (HID_QUIRK_HIDDEV) and introduces a new
quirk which forces the HIDINPUT interface to be ignored
(HID_QUIRK_IGNORE_HIDINPUT).
Note that Apple calls this receiver 'IRController4' (info taken
from Apple's driver Info.plist). Older Mac{Book,Mini,Pro}s seem
to all use the 'IRController1' device (USB id 05ac:8240) which
doesn't need those quirks.

Current HID layer does not report usage codes to the input layer. This feature
was previously removed, because it caused unnecessary storm of events in cases
of positioning devices, etc.
This patch adds reporting of usage codes as EV_MSC events only for key events.
We issue the EV_MSC event only if the state of the key corresponding to the
given code has changed, so that we don't report usages that are sent in every
report even if the state hasn't changed (for example Shift/Caps Lock/...
states as sent by various keyboards).
This functionality is required at least by KeyTouch in order to provide
convenient means for remapping the usage codes.

We have to ignore all non-LED usages in output fields if the
report descriptor of the device specifies any. If we don't do
so, the devices which contain the same usages both in input and
output reports with different parameters will mess things up. In
hid-input, we currently care only for the input usages, with exception
for LEDs. All other output usages should be properly handled by
appropriate force-feedback driver.

This keyboard emits a few usages that are not handled properly by
hid-input.
The usages from MSVENDOR page are colliding with Chicony Tactical
Pad device, so we have to distinguish in runtime. Ugly ...
Also, the buttons 1-5 have to be handled in a non-standard way,
as they are emitted by the keyboard in a bitfield-like fashion, but
the field is not presented as bit-field by the keyboard. The keys can't
be pressed simultaneously, so the handling we have is correct.
This patch also extends hid_keyboard[] with KPLeftParenthesis and
KPRightParenthesis as defined by Keyboard page in HUT 1.12. The
corresponding usages are also emitted by this keyboard.
