Linus Torvalds d381f45c89 Merge branch 'for-3.9/upstream-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid
Pull HID fix from Jiri Kosina:
 "Bugfix for a long-standing bug in logitech-dj driver causing all sorts
  of random initialization problems, finally debugged by Benjamin
  Tissoires with help of Bob Bowles."

  HID: logitech-dj: do not directly call hid_output_raw_report() during probe
2013-03-08 14:42:52 -08:00
Benjamin Tissoires dcd9006b1b HID: logitech-dj: do not directly call hid_output_raw_report() during probe
hid_output_raw_report() makes a direct call to usb_control_msg(). However,
some USB3 boards have shown that the usb device is not ready during the
.probe(). This blocks the entire usb device, and the paired mice, keyboards
are not functional. The dmesg output is the following:

[   11.912287] logitech-djreceiver 0003:046D:C52B.0003: hiddev0,hidraw0: USB HID v1.11 Device [Logitech USB Receiver] on usb-0000:00:14.0-2/input2
[   11.912537] logitech-djreceiver 0003:046D:C52B.0003: logi_dj_probe:logi_dj_recv_query_paired_devices error:-32
[   11.912636] logitech-djreceiver: probe of 0003:046D:C52B.0003 failed with error -32

Relying on the scheduled call to usbhid_submit_report() fixes the problem.

Linus Torvalds d895cb1af1 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs pile (part one) from Al Viro:
 "Assorted stuff - cleaning namei.c up a bit, fixing ->d_name/->d_parent
  locking violations, etc.

  The most visible changes here are death of FS_REVAL_DOT (replaced with
  "has ->d_weak_revalidate()") and a new helper getting from struct file
  to inode.  Some bits of preparation to xattr method interface changes.

  Misc patches by various people sent this cycle *and* ocfs2 fixes from

Vivien Didelot 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.

Benjamin Tissoires dc3e1d8052 HID: multitouch: make MT_CLS_ALWAYS_TRUE the new default class
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

Benjamin Tissoires c629dd7eb3 HID: multitouch: fix Win8 protocol for Sharp like devices
The Sharp LC-20FE1-W screen (04dd:9681) behaves like the Nexio 42".
It may report out of ranges values that are filtered out by relying
on the Contact Count HID field.
Adding the quirk MT_QUIRK_CONTACT_CNT_ACCURATE makes hid-multitouch
strongest against this kind of device, without breaking the current
devices.

Benjamin Tissoires c2517f62da HID: multitouch: add support for Nexio 42" panel
This device is the worst device I saw. It keeps TipSwitch and InRange
at 1 for fingers that are not touching the panel.
The solution is to rely on the field ContactCount, which is accurate
as the correct information are packed at the begining of the frame.

Unfortunately, CountactCount is most of the time at the end of the report.
The solution is to pick it when we have the whole report in raw_event.

Benjamin Tissoires 55978fa9dc HID: multitouch: use the callback "report" instead of sequential events
Nexio 42" devices requires to rely on the HID field Contact
Count to compute the valid values. However, this field is
most of the time at the end of the report, meaning that we
need to get the all report parsed before processing it.

This patch does not introduce functional changes.

Benjamin Tissoires 6d85d037d6 HID: core: add "report" hook, called once the report has been parsed
This callback is called when the parsing of the report has been done
by hid-core (so after the calls to .event). The hid drivers can now
have access to the whole report by relying on the values stored in
the different fields.

Benjamin Tissoires c284979aff HID: i2c-hid: fix i2c_hid_output_raw_report
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
in the command, leading to a non working command.

Simon Wood e25d780581 USB: HID: Steelseries SRW-S1 Add support controlling all LEDs simultaneously
This patch to the SRW-S1 driver adds the ability to control all
LEDs simultaneously as testing showed that it was slow (noticably!!)
when seting or clearing all the LEDs in turn.

It adds a 'RPMALL' LED, whose behavoir is asserted to all the LEDs in
the bar graph, individual LEDs can subsequently be turned on/off
individually.
