Linus Torvalds bc75450cc3 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid
Pull HID updates from Jiri Kosina:

 - Integrated Sensor Hub support (Cherrytrail+) from Srinivas Pandruvada

 - Big cleanup of Wacom driver; namely it's now using devres, and the
   standardized LED API so that libinput doesn't need to have root
   access any more, with substantial amount of other cleanups
   piggy-backing on top. All this from Benjamin Tissoires

 - Report descriptor parsing would now ignore and out-of-range System
   controls in case of the application actually being System Control.
   This fixes quite some issues with several devices, and allows us to
   remove a few ->report_fixup callbacks. From Benjamin Tissoires

 - ... a lot of other assorted small fixes and device ID additions

Masaki Ota 9a54cf462d HID: alps: fix multitouch cursor issue
Issue reproduction procedure:

1. three or more fingers put on Touchpad.
2. release fingers from Touchpad.
3. move the cursor by one finger.
4. the cursor does not move.

Cause:

We do not notify multi fingers state correctly to input subsystem.  For
example, when three fingers release from Touchpad, fingers state is 3 -> 0. It
needs to notify first, second and third finger's releasing state.

Fix this by not breaking out on z axis and move x,y,z input handling
code to the correct place so that it's in fact per-finger.

Frank Praznik 2a24293277 HID: sony: Defer the initial USB Sixaxis output report
When initially connected via USB the Sixaxis isn't fully initialized
until the PS logo button is pressed and won't send any input reports
nor will any state set by output reports be retained.

This adds a 'defer_initialization' flag to the sony_sc struct which,
when set, will delay sending any output reports until the first input
report has arrived. This flag is used with the USB Sixaxis to ensure
that any state sent will persist since, until the PS button is pushed,
any changes sent to the controller via an output report will be lost
after a couple of seconds.

The initial state of the controller is still configured at the time
of the initial connection and won't be internally modified after that,
so any state set by the user between that time and the recepit of the
first input report won't be lost.

Frank Praznik 0f3982308b HID: sony: Relax duplicate checking for USB-only devices
Some USB-only devices which masquerade as Sixaxis controllers report the
same generic Bluetooth address for all hardware when queried via the HID
report. This causes these devices to be wrongly rejected as duplicates
when more than one is connected at once.

This introduces a connection type comparison when checking for duplicates
and only rejects the newly connected device if the existing matching
device is connected using a different connection protocol.

The results of the connection type comparison are also used when
registering power supply info as the device Bluetooth address is used
as the unique identifier string.  In cases where more than one valid
device has the same Bluetooth address the device ID is now appended
to the power supply name string to avoid name collisions when
registering the power supply information.

Michel Hermier 52dc085a50 Revert "HID: microsoft: fix invalid rdesc for 3k kbd"
This reverts commit 3ccc60f9d8.

While investigating bug https://bugzilla.kernel.org/show_bug.cgi?id=37982 ,
there was solid evidences that Microsoft reused the same report
descriptor for the its Digital Media keyboard series.

Since 1989dad "HID: input: ignore System Control application usages if not
System Controls", the keyboard series do not produce a spurious joystick
input device inode without needing to patch the problematic report
descriptor. As such the MS_RDESC_3K reportdescriptor fixup can be removed.

Kai-Heng Feng 04fd4cb0b0 HID: alps: fix stick device not working after resume
The stick device does not work after resume, add U1_SP_ABS_MODE flag can
make the device work after resume.

This has been discovered by pure guesswork, based on how the existing code uses
U1_TP_ABS_MODE flag on both initialization and resume.

I also tested the the patch on an ALPS touchpad without stick device, did not
notice any side effect on suspend/resume, so I made the U1_SP_ABS_MODE flag
mandatory.

Benjamin Tissoires 1989dada7c HID: input: ignore System Control application usages if not System Controls
Microsoft is reusing its report descriptor again and again, and part of it
looks like this:

0x05, 0x01,                    // Usage Page (Generic Desktop)        299
0x09, 0x80,                    // Usage (System Control)              301
0xa1, 0x01,                    // Collection (Application)            303
0x85, 0x03,                    //  Report ID (3)                      305
0x19, 0x00,                    //  Usage Minimum (0)                  307
0x29, 0xff,                    //  Usage Maximum (255)                309
0x15, 0x00,                    //  Logical Minimum (0)                311
0x26, 0xff, 0x00,              //  Logical Maximum (255)              313
0x81, 0x00,                    //  Input (Data,Arr,Abs)               316
0xc0,                          // End Collection                      318

While there is nothing wrong in term of processing, we do however blindly
map the full usage range (it's an array) from 0x00 to 0xff, which creates
some interesting axis, like ABS_X|Y, and a bunch of ABS_MISC + n.

While libinput and other stacks don't care that much (we can detect them),
joydev is very happy and attaches itself to the mouse or keyboard.

The problem is that joydev now handles the device as a joystick, but given
that we have a HID array, it sets all the ABS_* values to 0. And in its
world, 0 means -32767 (minimum value), which sends spurious events to games
(think Steam).

It looks like hid-microsoft tries to tackle the very same problem with its
.report_fixup callback. But fixing the report descriptor is an endless task
and is quite obfuscated.

So take the hammer, and decide that if the application is meant to be
System Control, any other usage not in the System Control range should
be ignored.

Srinivas Pandruvada 3703f53b99 HID: intel_ish-hid: ISH Transport layer
The ISH transport layer (ishtp) is a bi-directional protocol implemented
on the top of PCI based inter processor communication layer. This layer
offers:
- Connection management
- Flow control with the firmware
- Multiple client sessions
- Client message transfer
- Client message reception
- DMA for RX and TX for fast data transfer

Refer to Documentation/hid/intel-ish-hid.txt for
overview of the functionality implemented in this layer.

Jason Gerecke 003f50ab67 HID: wacom: Update last_slot_field during pre_report phase
If a touchscreen contains both multitouch and single-touch reports in its
descriptor in that order, the driver may overwrite information it saved
about the format of the multitouch report. This can cause the report
processing code to get tripped up and send an incorrect event stream to
userspace.

In particular, this can cause last_slot_field to be overwritten with the
result that the driver prematurely assumes it has finished processing a
slot and sending the ABS_MT_SLOT event at the wrong point in time,
associating events for the current contact with the following contact
instead.

To prevent this from occurring, we update the value of last_slot_field
durring the pre_report phase to ensure that it is correct for the report
that is to be processed.

Ping Cheng 1924e05e60 HID: wacom - add touch_arbitration parameter to wacom module
Touch arbitration is always on in wacom.ko. However, there are
touch enabled applications use both pen and touch simultaneously.
We should provide an option for userland to decide if they want
arbitration on or off.

This patch sets default touch_arbitration to on since most userland
apps are not ready to process pen and touch events simultaneously.
In the future, when userland is ready to accept pen and touch events
together, we will switch default touch_arbitration to off.

Jason Gerecke 41372d5d40 HID: wacom: Augment 'oVid' and 'oPid' with heuristics for HID_GENERIC
The 'oVid' and 'oPid' variables used by wacom_are_sibling are a hacky
solution to the problem of the driver historically having few good
heuristics to use in determining if two devices should be considered
siblings or not. While it works well enough for explicitly supported
devices, it offers no help for HID_GENERIC devices. Now that we have
a bit more information (e.g. direct/indirect) available to us though,
we should make use of it it to improve the pairing of such devices.

so we introduce a new WACOM_DEVICETYPE_DIRECT that signals this to other

Looks like upowerd is ignoring this since October 2013, so there is
no need to keep this around in the kernel.
And as mentioned in 8aaa592 (linux: Ignore ACs coming from devices) in
the upower tree, "We already have enough information on the device
battery".

Benjamin Tissoires 9698329628 HID: wacom: power_supply: mark the type as USB
When upowerd detects a new device, it tries to map this new device to
an input to guess its kind. It works OK for wired tablets when the
wireless module and its battery are attached, but not so well when
connected over wireless.
In that case, the battery is attached to the wireless HID node, not
the Pen or Pad HID node. So there is no input node as a parent of the
reported battery, which means it will be showed as a computer battery
in gnome-control-center.

If we set the power supply type to USB, upowerd has a heuristic that
detects "wacom_" in the name of the power_supply, and set the type to
tablet. So it's now clear that the reported battery of from a tablet.

The code for 21UX2 and 24HD makes the LED group 1 on the left, and
the group 0 on the right. The buttons are ordered in the other way,
but libwacom already exports those that way. So we simply can't reassign
LED group 0 to the left buttons, and have to quirk the incoming data...

Benjamin Tissoires 34736aa96e HID: wacom: leds: handle the switch of the LEDs directly in the kernel
The EKR switches the LED directly, and there is no point in having
userspace handling the switch it self when it's easy enough to do
in the kernel.

The other benefit is that now userspace does not need to have root access
to the LED but need only to read them with user privileges.

Benjamin Tissoires 589e506020 HID: wacom: leds: actually release the LEDs on disconnect
There is a bug (?) in devm_led_classdev_register() in which its increments
the refcount of the parent. If the parent is an input device, that means
the ref count never reaches 0 when devm_input_device_release() gets called.
This means that the LEDs and all the devres resources attached to the
input device are not released.

Manually force the release of the group so that the leds are released once
we are done using them.
