We normally get EXT hotplug events or poll for MP hotplugging so we
don't need to force extension port initialization during device setup.
But for gen20 devices, we disable MP polling because MP is always
present. However, this prevents MP initialization during device setup
and users need to plug another extension to trigger EXT/MP detection.
Therefore, we now trigger EXT/MP detection during device setup
automatically. This also avoids slightly delayed extension detection
and provides sysfs child-devices prior to the "changed"-uevent during
device setup.

Balance-Boards provide 3 16bit calibration values for each of the 4

sysfs attribute.
We also re-read the calibration data from the device whenever user-space
attempts to read this file. On normal Nintendo boards, this always
produces the same results, however, on some 3rd party devices these values
change until the device is fully initialized. As I have currently no idea
how long to wait until it's ready (sometimes takes up to 10s?) we provide
a simple workaround for users by reading this file.
If we, at some point, figure out how it works, we can implement it in the

The Wii Remote has several extension ports. The first port (EXT) provides
hotplug events whenever an extension is plugged. The second port (MP)
does not provide hotplug events by default. Instead, we have to map MP
into EXT to get events for it.
This patch introduces hotplug support for extensions. It is fairly
complicated to get this right because the Wii Remote sends a lot of
noise-hotplug events while activating extension ports. We need to filter
the events and only handle the events that are real hotplug events.
Mapping MP into EXT is easy. But if we want both, MP _and_ EXT at the same
time, we need to map MP into EXT and enable a passthrough-mode. This will
then send real EXT events through the mapped MP interleaved with real MP
events. But once MP is mapped, we no longer have access to the real EXT
registers so we need to perform setup _before_ mapping MP. Furthermore, we
no longer can read EXT IDs so we cannot verify if EXT is still the same
extension that we expect it to be.
We deal with this by unmapping MP whenever we got into a situation where
EXT might have changed. We then re-read EXT and MP and remap everything.
The real Wii Console takes a fairly easy approach: It simply reconnects to
the device on hotplug events that it didn't expect. So if a program wants
MP events, but MP is disconnected, it fails and reconnects so it can wait
for MP hotplug events again.
This simplifies hotplugging a lot because we just react on PLUG events and
ignore UNPLUG events.
The more sophisticated Wii applications avoid reconnection (well, they
still reconnect during many weird events, but at least not during UNPLUG)
but they start polling the device. This allows them to disable the device,
poll for the extension ports to settle and then initialize them again.
Unfortunately, this approach fails whenever an extension is replugged
while it is initialized. We would loose UNPLUG events and polling the
device later will give unreliable results because the extension port might
be in some weird state, even though it's actually unplugged.
Our approach is a real HOTPLUG approch. We keep track of the EXT and
mapped MP hotplug events whenever they occur. We then re-evaluate the
device state and initialize any possible new extension or deinitialize any
gone extension. Only during initialization, we set an extension port
ACTIVE. However, during an unplug event we mark them as INACTIVE. This
guarantess that a fast UNPLUG -> PLUG event sequence doesn't keep them
marked as PLUGGED+ACTIVE but only PLUGGED.
To deal with annoying noise-hotplug events during extension mapping, we
simply rescan the device before performing any mapping. This allows us to
ignore all the noise events as long as the device is in the correct state.
Long story short: EXT and MP registers are sparsely known and we need to
jump through hoops to get reliable HOTPLUG working. But while Nintendo
needs *FOUR* Bluetooth reconnections for the shortest imaginable
boot->menu->game->menu->shutdown sequence, we now need *ZERO*.
As always, 3rd party devices tend to break whenever we behave differently
than the original Wii. So there are also devices which _expect_ a
disconnect after UNPLUG. Obviously, these devices won't benefit from this
patch. But all official devices were tested extensively and work great
during any hotplug sequence. Yay!

incorrectly assume our request succeeded.
Note that the underlying connection is required to be reliable and does
retransmission itself. So it is safe to assume that if the transmission

So chances are pretty high that we have an up-to-date battery

then return battery values from the cache if the query fails.
This works around a power_supply limitation in that it requires us to be
able to query the device during power_supply registration and
removal. Otherwise, "add" or "remove" udev events are not sent. If
we answer these requests from our cache instead, we avoid dropping these
events and no longer cause warnings printed.

Nintendo produced many different devices that are internally based on the
Wii Remote protocol but provide different peripherals. To support these
devices, we need to schedule a device detection during initialization.
Device detection includes requesting a status report, reading extension
information and then evaluating which device we may be dealing with.
We currently detect gen1 and gen2 Wii Remote devices. All other devices
are marked as generic devices. More detections will be added later.
In followup patches we will be using these device IDs to control which
peripherals to initialize. For instance if a device is known to have no IR
camera, there is no need to provide the IR input device nor trying to
access IR registers. In fact, there are 3rd party devices that break if we
try things like this (hurray!).
The init_worker will be scheduled whenever we get hotplug events. This
isn't implemented, yet and will be added later. However, we need to make
sure that this worker can be called multiple times.

power_supply core has the bad habit of calling our battery callbacks
from within power_supply_register(). Furthermore, if the callbacks
fail with an unhandled error code, it will skip any uevent that it
might currently process.
So if HID-core registers battery devices, an "add" uevent is generated
and the battery callbacks are called. These will gracefully fail due
to timeouts as they might still hold locks on event processing. One
could argue that this should be fixed in power_supply core, but the
least we can do is to signal ENODATA so power_supply core will just
skip the property and continue with the uevent.
This fixes a bug where "add" and "remove" uevents are skipped for
battery devices. upower is unable to track these devices and currently
needs to ignore them.
This patch also overwrites any other error code. I cannot see any reason
why we should forward protocol- or I/O-errors to the power_supply core.
We handle these errors in hid_ll_driver later, anyway, so just skip
them. power_supply core cannot do anything useful with them, anyway,
and we avoid skipping important uevents and confusing user-space.
Thanks a lot to Daniel Nicoletti for pushing and investigating

With the current i2c hid driver set/get report does not work

we do not get events.
The problem is that i2c hid driver in function i2c_hid_request
sets length equal to default buffer size for which the sensor
hub does not respond on get/set commands. Use report length
and calculate it based on report size and id.

Since kernel 3.7, it appears that the input registration occured before
the end of magicmouse_setup_input(). This is shown by receiving a lot of
"EV_SYN SYN_REPORT 1" instead of normal "EV_SYN SYN_REPORT 0".
This value means that the output buffer is full, and the user space
is loosing events.
Using .input_configured guarantees that the race is not occuring, and that
the call of "input_set_events_per_packet(input, 60)" is taken into account
by input_register().

It turns out the Wii accepts any status reports from clients reduced to
"BB BB" key data only, as long as the report actually includes key data at
the first two bytes.
The official devices don't send these reduced reports, but of course, 3rd
party devices make great use of this feature.
Hence, add parsers for these reduced reports for every matching report.
Also change the logic how we find handlers. There is no reason to call

Historically, logitech-dj communicated with the device during probe()
to query the list of devices attached. Later, a change was introduced
to hid-core that prevented incoming packets for a device during
probe(), as many drivers are unable to handle such input. That change
broke the device enumeration in logitech-dj, so commit
596264082f was introduced to workaround that by waiting for
normal input before enumerating devices.
Now that drivers can opt-in to receive input during probe, this patch
changes logitech-dj to do that, so that it can successfully complete
enumeration of devices during probe().

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.

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

By running a test on all the traces of the devices I have,
I noticed that the class MT_CLS_ALWAYS_TRUE could handle all
the devices I've seen so far without any other quirks.
I guess this is the behavior Win 7 requires in its driver.
We can change the default class then and keep the existing classes
for backward compatibility and performances for some of them.
Two operations have been done:
* replaced MT_CLS_DEFAULT by MT_CLS_NSMU
* then replaced MT_CLS_ALWAYS_TRUE by MT_CLS_DEFAULT

HID: i2c-hid: fix i2c_hid_output_raw_report
HID: usbhid: quirk for Formosa IR receiver
HID: remove x bit from sensor doc
i2c_hid_output_raw_report is used by hidraw to forward set_report requests.
The current implementation of i2c_hid_set_report needs to take the
report_id as an argument. The report_id is stored in the first byte
of the buffer in argument of i2c_hid_output_raw_report.
Not removing the report_id from the given buffer adds this byte 2 times

There are some Sony clone gamepads that are incompatible
with PS3 since firmware 3.50, as they decided to prevent those
devices to work, without any good technical reason. I was one of those
'blessed' people affected by their niceness with their customers.
Marcelo also has another device with a similar problem.
Perhaps due to Sony's way to block the device, damaging the device's
eeprom, or perhaps because they just have a different, broken Report
descriptor, there are 3 buttons that don't work on both devices
(the ones equivalent to square, round and X).
What it happens is that the descriptor generate weird EV_ABS events
to those buttons, instead of EV_MSC/EV_KEY.
A fix that seems to be enough for them is to return the original
sixaxis table instead of the broken one. That's what this patch
does.
Yet, there are some missing entries at the used keytable. On my
tests, all keys are now producing the right events, but the reported
keycodes look weird:
"square" key: (Button.0010 = 1)
1355524363.460835: event type EV_MSC(0x04): scancode = 0x90010
1355524363.460835: event type EV_KEY(0x01) key_up: BTN_DEAD(0x0001)
"round" key: (Button.000e = 1)
1355524410.908705: event type EV_MSC(0x04): scancode = 0x9000e
1355524410.908705: event type EV_KEY(0x01) key_down: (0x0001)
1355524410.971788: event type EV_MSC(0x04): scancode = 0x9000e
1355524410.971788: event type EV_KEY(0x01) key_up: (0x0001)
"X" key: (Button.000f = 1)
1355524384.880813: event type EV_MSC(0x04): scancode = 0x9000f
1355524384.880813: event type EV_KEY(0x01) key_down: (0x0001)
1355524384.979815: event type EV_MSC(0x04): scancode = 0x9000f
1355524384.979815: event type EV_KEY(0x01) key_up: (0x0001)
The rationale is likely due to those entries at rdesc table, where the
Kernel were not likely able to parse:
Button.000d ---> Key.?
Button.000e ---> Key.?
Button.000f ---> Key.?
Button.0010 ---> Key.BtnDead
Button.0011 ---> Key.?
Button.0012 ---> Key.?
Button.0013 ---> Key.?

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.

Button names for USB gamepads are currently assigned incorrectly, as the evdev

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.

Our device didn't contain HID_DG_CONTACTMAX usage. This usage use to describe
touchscreen's maxcontacts for hid-multitouch.c to get maxcontacts automatic. We
fix the device that driver can get maxcontact from our device, hence it doesn't
need .maxcontact=10. Now there is just one device class can fix all our PWT
touchscreen.

Microsoft Digital Media Keyboard 3000 has two interfaces, and the
second one has a report descriptor with a bug. The second collection
says:
05 01 -- global; usage page -- 01 -- Generic Desktop Controls
09 80 -- local; usage -- 80 -- System Control
a1 01 -- main; collection -- 01 -- application
85 03 -- global; report ID -- 03
19 00 -- local; Usage Minimum -- 00
29 ff -- local; Usage Maximum -- ff
15 00 -- global; Logical Minimum -- 0
26 ff 00 -- global; Logical Maximum -- ff
81 00 -- main; input
c0 -- main; End Collection
I.e. it makes us think that there are all kinds of usages of system
control. That the keyboard is a not only a keyboard, but also a
joystick, mouse, gamepad, keypad, etc. The same as for the Wireless
Desktop Receiver, this should be Physical Min/Max. So fix that
appropriately.

tcu sysfs attr was used to only control calibration process so far. Direct
sensor register access possibility has been revealed. Allowing readout of tcu
permits usage of this feature.

Pull workqueue changes from Tejun Heo:
"This is workqueue updates for v3.7-rc1. A lot of activities this
round including considerable API and behavior cleanups.
* delayed_work combines a timer and a work item. The handling of the
timer part has always been a bit clunky leading to confusing
cancelation API with weird corner-case behaviors. delayed_work is
updated to use new IRQ safe timer and cancelation now works as
expected.
* Another deficiency of delayed_work was lack of the counterpart of
mod_timer() which led to cancel+queue combinations or open-coded
timer+work usages. mod_delayed_work[_on]() are added.
These two delayed_work changes make delayed_work provide interface
and behave like timer which is executed with process context.
* A work item could be executed concurrently on multiple CPUs, which
is rather unintuitive and made flush_work() behavior confusing and
half-broken under certain circumstances. This problem doesn't
exist for non-reentrant workqueues. While non-reentrancy check
isn't free, the overhead is incurred only when a work item bounces
across different CPUs and even in simulated pathological scenario
the overhead isn't too high.
All workqueues are made non-reentrant. This removes the
distinction between flush_[delayed_]work() and
flush_[delayed_]_work_sync(). The former is now as strong as the
latter and the specified work item is guaranteed to have finished
execution of any previous queueing on return.
* In addition to the various bug fixes, Lai redid and simplified CPU
hotplug handling significantly.
* Joonsoo introduced system_highpri_wq and used it during CPU
hotplug.
There are two merge commits - one to pull in IRQ safe timer from
tip/timers/core and the other to pull in CPU hotplug fixes from
wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."
Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.
Tejun pointed out a few of them, I fixed a couple more.

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(-)
All of these patches have been in the linux-next tree already.
