2ebaebcf31 HID: input: hid-input remove hid_output_raw_report call
hid_output_raw_report() is not a ll_driver callback and should not be used.
To keep the same code path than before, we are forced to play with the
different hid_hw_* calls: if the usb or i2c device does not support
direct output reports, then we will rely on the SET_REPORT HID call.

5f5750d2e4 HID: sony: Fix work queue issues.
Don't initialize force-feedback for devices that don't support it to avoid calls
to schedule_work() with an uninitialized work_struct.

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 sony_destroy_ff() to avoid a compiler warning since it is no longer used.

Both cp2112_read_req() and cp2112_write_req() are returning negative
value in cases of error, but cp2112_xfer() is storing the return

Fix this by making 'count' signed type.

e932d81786 HID: add hid-cp2112 driver
This patch adds support for the Silicon Labs CP2112 "Single-Chip HID USB to
SMBus Master Bridge."

This is a HID device driver which registers as an i2c adapter and gpiochip to
expose these functions of the CP2112. The customizable USB descriptor fields
are exposed as sysfs attributes.  The SMBus byte-read, byte-data-read/write,
and word-data-read transfer modes have been tested by talking to an i2c
sensor.  The GPIO functions and USB descriptor field programming have also
been tested.

ca2ed12f16 HID: hid-sensor-hub: Processing for duplicate physical ids
In HID sensor hub, HID physical ids are used to represent different sensors.
For example physical id of 0x73 in usage page = 0x20, represents an
accelerometer. The HID sensor hub driver uses this physical ids to create
platform devices using MFD. There is 1:1 correspondence between an phy id and a
client driver.

But in some cases these physical ids are reused. There is a phy id 0xe1, which
specifies a custom sensor, which can exist multiple times to represent various
custom sensors. In this case there can be multiple instances of client MFD
drivers, processing specific custom sensor. In this case when client driver
looks for report id or a field index, it should still get the report id
specific to its own type. This is also true for reports, they should be
directed towards correct instance.  This change introduce a way to parse and
tie physical devices to their correct instance.

Summary of changes:
- To get physical ids, use collections. If a collection of type=physical
  exist then use usage id as in the name of platform device name
- As part of the platform data, we assign a hdsev instance, which has
  start and end of collection indexes. Using these indexes attributes
  can be tied to correct MFD client instances
- When a report is received, call callback with correct hsdev instance.
  In this way using its private data stored as part of its registry, it
  can distinguish different sensors even when they have same physical and
  logical ids.

  This patch is co-authored with Archana Patni <archna.patni@intel.com>.

e02cee4819 HID: hid-sensor-hub: Add selector api
In some report descriptors, they leave holes in the selectors. In
this case if we use hardcoded selector values, this will result
in invalid values. For example, if there is selectors defined for
Power State from OFF to D0 to D3. We can't use indexes of these states
if some states are not implemented or not present in the report decriptors.
In this case, we need to get the indexes from report descriptors.

One API is added to get the index of a selector. This API will
search for usage id in the field usage list and return the index.

218eb9ed84 HID: hid-sensor-hub: quirk for STM Sensor hub
Added STM sensor hub vendor id in HID_SENSOR_HUB_ENUM_QUIRK to
fix report descriptors. These devices uses old FW which uses
logical 0 as minimum. In these, HID reports are not using proper
collection classes. So we need to fix report descriptors,for
such devices. This will not have any impact, if the FW uses
logical 1 as minimum.

We look for usage id for "power and report state", and modify
logical minimum value to 1.

This is a follow-up patch to commit id 875e36f8.

34f439e4af HID: i2c-hid: add runtime PM support
This patch adds runtime PM support for the HID over I2C driver. When the
i2c-hid device is first opened we power it on and on the last close we
power it off. This is actually what the driver is already doing but in
addition it allows subsystems, like ACPI power domain to power off the
device during runtime PM suspend, which should save even more power.

The implementation is not the most power efficient because it needs some
interaction from the userspace (e.g close the device node whenever we are
no more interested in getting events), nevertheless it allows us to save
some power and works with devices that are not wake capable.

Merge tag 'pm+acpi-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management updates from Rafael Wysocki:
 "As far as the number of commits goes, the top spot belongs to ACPI
  this time with cpufreq in the second position and a handful of PM
  core, PNP and cpuidle updates.  They are fixes and cleanups mostly, as
  usual, with a couple of new features in the mix.

  The most visible change is probably that we will create struct
  acpi_device objects (visible in sysfs) for all devices represented in
  the ACPI tables regardless of their status and there will be a new
  sysfs attribute under those objects allowing user space to check that
  status via _STA.

  Consequently, ACPI device eject or generally hot-removal will not
  delete those objects, unless the table containing the corresponding
  namespace nodes is unloaded, which is extremely rare.  Also ACPI
  container hotplug will be handled quite a bit differently and cpufreq
  will support CPU boost ("turbo") generically and not only in the
  acpi-cpufreq driver.

  Specifics:

   - ACPI core changes to make it create a struct acpi_device object for
     every device represented in the ACPI tables during all namespace
     scans regardless of the current status of that device.  In
     accordance with this, ACPI hotplug operations will not delete those
     objects, unless the underlying ACPI tables go away.

   - On top of the above, new sysfs attribute for ACPI device objects

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".

Benjamin Tisssoires
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.

 ----

The Dualshock 4 light bar has 3 separate RGB LEDs that can range in

state

Changed the module to support an arbitrary number of LEDs instead of being
hardcoded to 4.

Fix kernel warning and failure to register sensor hub devices with MFD.  Now
many devices has in-built sensor hubs. So by default this HID hub, is properly
parsed and register individual sensors as platform device using MFD framework.
But if a second sensor hub is attached via USB, which has same sensors, it will
result in kernel warning and failure to register MFD cell as the platform
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
duplicate sysfs file names.

 * 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
 a 0 indexed or 1 indexed device and to adjust appropriately.  It also
 drops a previous kconfig option that allowed this issue to be worked around
 at build time.

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.

94037efe81 HID: i2c-hid: disable interrupt on suspend
When an I2C HID device is powered of during system sleep, as a result of
removing its power resources (by the ACPI core) the interrupt line might go
low as well. This results inadvertent interrupt and wakes the system from
sleep immediately.

To prevent this we disable the device interrupt in the drivers suspend
method and enable it on resume. The device can still wake the system up if
it is wake capable (this also means that not all of its power will be
removed to keep the interrupt line high).
