c8de9dbb35 HID: sony: Fix work queue issues
Only initialize force feedback for devices that actually support it (Sixaxis and
Dualshock 4) to prevent calls to schedule_work() with an uninitialized work
queue.

Move the cancel_work_sync() call out of sony_destroy_ff() since the state worker
is used for the LEDs even when force-feedback is disabled.

Remove the sony_destroy_ff() function since it is no longer used.

whether each of the RGB LEDs is lit (ie not off), but no indication

returns the value (rather than just off=0, on=LED_FULL).

875e36f8a2 HID: hid-sensor-hub: Fix buggy report descriptors
This addresses regression caused by commit id "751d17e23a9f7"
 iio: hid-sensors: Fix power and report state.
This commit removed a quirk, to change the enumeration base
to 1 from 0 based on an CONFIG paramter. There was objection to
add more changes under this quirk, instead suggested to add an
HID quirk. But there is no easy way to add HID qurik as the
reports are not properly using collection class.

The solution was to use logical minimum, which is a correct way.
There were changes done in firmware to address this.

Unfortunately some devices, still use old FW and can't be upgraded
to newer version on Linux devices as there is no FW upgrade tool
available for Linux devices. So we need to fix report descriptors,
for such devices. This will not have any impact, if the FW uses
logical 1 as minimum.

In this patch we look for usage id for "power and report state", and
modify logical minimum value to 1.

Background on enum:
In the original HID sensor hub firmwares all Named array enums were
to 0-based. But the most recent hub implemented as 1-based,
because of the implementation by one of the major OS vendor.
Using logical minimum for the field as the base of enum. So we add
logical minimum to the selector values before setting those fields.
Some sensor hub FWs already changed logical minimum from 0 to 1
to reflect this and hope every other vendor will follow.
There is no easy way to add a common HID quirk for NAry elements,
even if the standard specifies these field as NAry, the collection
used to describe selectors is still just "logical".

42c22dbf81 HID: logitech-dj: Fix USB 3.0 issue
This fix (not very clean though) should fix the long time USB3
issue that was spotted last year. The rational has been given by
Hans de Goede:

 ----

I think the most likely cause for this is a firmware bug
in the unifying receiver, likely a race condition.

The most prominent difference between having a USB-2 device
plugged into an EHCI (so USB-2 only) port versus an XHCI
port will be inter packet timing. Specifically if you
send packets (ie hid reports) one at a time, then with
the EHCI controller their will be a significant pause
between them, where with XHCI they will be very close
together in time.

The reason for this is the difference in EHCI / XHCI
controller OS <-> driver interfaces.

For non periodic endpoints (control, bulk) the EHCI uses a
circular linked-list of commands in dma-memory, which it
follows to execute commands, if the list is empty, it
will go into an idle state and re-check periodically.

The XHCI uses a ring of commands per endpoint, and if the OS
places anything new on the ring it will do an ioport write,
waking up the XHCI making it send the new packet immediately.

For periodic transfers (isoc, interrupt) the delay between
packets when sending one at a time (rather then queuing them
up) will be even larger, because they need to be inserted into
the EHCI schedule 2 ms in the future so the OS driver can be
sure that the EHCI driver does not try to start executing the
time slot in question before the insertion has completed.

So a possible fix may be to insert a delay between packets
being send to the receiver.

 ----

I tested this on a buggy Haswell USB 3.0 motherboard, and I always
get the notification after adding the msleep.

But if a second sensor hub is attached via USB, which has same sensors, it will

device sysfs file name will be same as created by in-built sensor hubs. This
patch sets MFD cell id to PLATFORM_DEVID_AUTO. In this way there will never be

 interpretation of the specification and hence indexing some arrays from 1
 rather than 0.  The fix takes advantage of the logical min and max reading
 facilities introduced by the precursor patch to figure out whether we have

Second round of IIO fixes for the 3.13 cycle.

2 fixes here.

* The gp2ap020a00f is a simple missing kconfig dependency.

* The hid sensors hub fix is a work around for an issue introduced by hardware
changes due to a certain large software vendor having an 'interesting'
interpretation of the specification and hence indexing some arrays from 1
rather than 0.  The fix takes advantage of the logical min and max reading
facilities introduced by the precursor patch to figure out whether we have

dcdc50e72b HID: logitech-dj: add HIDRAW dependency in Kconfig
hid-logitech-dj.c driver needs hidraw to work correctly. Without
hidraw, hid-logitech-dj.c fails during probe() and Logitech
Unifying devices HID reports aren't recognized.

The unifying receiver has 3 usb interfaces. When hid-logitech-dj driver is
loaded, interfaces 0 and 1 are discarded.

Interface 2 consists of a hid class interface with 3 collections, each of
which sports the 'vendor' usage, thus, there is no reason for hid_input to
claim any of them. On the other hand, hidraw has no issue in claiming the
collections, even if they are 'vendor'. As of today, hid-logitech-dj uses
hidraw api to send configuration/control reports to interface 2 of the
Unifying receiver.

Without the hid-logitech-dj driver, interfaces 0 and 1 are claimed by
hid-input, as they correspond to a keyboard and a mouse. But that is not
relevant to the discussion.

56d0c8b7c8 HID: add support for Logitech Dual Action gamepads
I have two Logitech Dual Action gamepads, both have same Vendor/Device id pair.
Newest gamepad (A) can switch between old mode (HID) and XBox gamepad emulation
mode. Old gamepad (B) can only work in HID mode.  In HID mode gamepad A sends
many EPIPE errors during initialization and was disconnected immediately after
connect  to usb port. It works fine in Win and Mac. After adding NOGET quirk in
driver, it was working properly.  Gamepad B works fine before and after
changes. I tested both gamepads with 3.8.0 and 3.11.6 kernels  with modified
driver. Follow patch can apply for current git kernel version. I can send pcap
log from usb bus with both gamepads or any other additional information if it
is needed

9f740ffa81 HID: hid-sensor-hub: Add logical min and max
Exporting logical minimum and maximum of HID fields as part of the
hid sensor attribute info. This can be used for range checking and
to calculate enumeration base for NAry fields of HID sensor hub.
