By default when using bluetooth the DS4 reports data at about 1kHz,
which is quite fast especially on weak devices. We now make the
device use the USB poll interval, which is a fixed 4ms. In addition
we make the value adjustable through sysfs.

The error handling in sony_input_configured is a little tricky. It
is not easy to add other goto's as not all codepaths have logic
for adding this attribute. Luckily we are setting the value for the
attribute to a default value, so we can use that to detect if we need
to remove the file.

The navigation controller is a DS3 (sixaxis) with fewer physical
axes and buttons. It utilizes the same HID report as the DS3 and
thus reports axes/buttons which aren't physically present.
Currently many non-existing buttons and axes are reported, which
we are now removing.

For the axes/buttons which do exist, we make the axis/button mapping
similar to the DS3.

The axis and button mapping for the DS3 is strange. This is mostly
due to the device reporting many axes as for every digital button
it also has an analog button. Due to amount of analog values it
is even leaking well into the MT axes range.

We felt it is best to remove the many analog buttons and just report
digital and comply to the Linux gamepad spec. The analog buttons are
rarely used on the official platform, let alone on Linux.

This patch does remove motion sensor support (added back in another
patch).

This patch adds a new quirk, which allows us to differentiate

been treated the same, but handling of calibration data differs
as the dongle behaves like Bluetooth, for other requests it
behaves like USB.

another patch in this series will add more dongle logic, so this

The DS4 in BT mode sends initial input reports through report 1, which
is described in the HID report descriptors. When activated after sending
a certain feature report, the device uses report 17.

Currently the hid-sony driver fixes up the BT HID report descriptors,
so the HID layer can manage input reports for report 17.

We think it is best to eliminate this fixup and do the handling ourselves,
which is what this patch does. The main motivation is that there are
various users of DS4 through hidraw, including various cross-platform
applications/games, which have their own HID parsing across Linux/Win/OSX.
Due to the fixup the descriptors differ, which is causing pain for many
developers including major game publishers (who reached out privately).
Without the fixup, the Windows titles also have a fighting chance for
working on Wine, which provides HID support now. Overall it felt
best because of these reasons to remove the fixup.

The DS4 motion sensors require calibration for accurate operation.

The DS4 motion sensors are currently mapped by the hid-core driver
to non-existing axes in between ABS_MISC and ABS_MT_SLOT, because
the device already exhausted ABS_X-ABS_RZ. For a part the mapping
by hid-core is accomplished by a fixup in hid-sony as the motion
axes actually use vendor specific usage pages.

This patch makes the DS4 use a separate input device for the motion
sensors and reports acceleration data through ABS_X-ABS_Z and
gyroscope data through ABS_RX-ABS_RZ. In addition it extends the
event spec to allow gyroscope data through ABS_RX-ABS_RZ when
INPUT_PROP_ACCELEROMETER is set. This change was suggested by
Peter Hutterer during a discussion on linux-input.

Pull pin control updates from Linus Walleij:
 "Pin control bulk changes for the v4.11 kernel cycle.

  Core changes:

   - Switch the generic pin config argument from 16 to 24 bits, only use
     8 bits for the configuration type. We might need to encode more
     information about a certain setting than we need to encode
     different generic settings.

   - Add a cross-talk API to the pin control GPIO back-end, utilizing
     pinctrl_gpio_set_config() from GPIO drivers that want to set up a
     certain pin configuration in the back-end.

     This also includes the .set_config() refactoring of the GPIO chips,
     so that they pass a generic configuration for things like
     debouncing and single ended (typically open drain). This change has
     also been merged in an immutable branch to the GPIO tree.

   - Take hogs with a delayed work, so that we finalize probing a pin
     controller before trying to get any hogs.

   - For pin controllers putting all group and function definitions into
     the device tree, we now have generic code to deal with this and it
     is used in two drivers so far.

   - Simplifications of the pin request conflict check.

   - Make dt_free_map() optional.

  Updates to drivers:

   - pinctrl-single now use the generic helpers to generate dynamic
     group and function tables from the device tree.

   - Texas Instruments IOdelay configuration driver add-on to
     pinctrl-single.

   - i.MX: use radix trees to store groups and functions, use the new
     generic group and function helpers to manage them.

   - Intel: add support for hardware debouncing and 1K pull-down. New
     subdriver for the Gemini Lake SoC.

   - Renesas SH-PFC: drive strength and bias support, CAN bus muxing,
     MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791.

   - Aspeed: use syscon cross-dependencies to set up related bits in the
     LPC host controller and display controller.

   - Aspeed: finalize G4 and G5 support. Fix mux configuration on GPIOs.
     Add banks Y, Z, AA, AB and AC.

   - AMD: support additional GPIO.

   - STM32: set this controller to strict muxing mode. STM32H743 MCU
     support.

   - Allwinner sunxi: deep simplifications on how to support subvariants
     of SoCs without adding to much SoC-specific data for each
     subvariant, especially for sun5i variants. New driver for V3s SoCs.
     New driver for the H5 SoC. Support A31/A31s variants with the new
     variant framework.

   - Mvebu: simplifications to use a MMIO and regmap abstraction. New
     subdrivers for the 98DX3236, 98DX5241 SoCs.

   - Samsung Exynos: delete Exynos4415 support. Add crosstalk to the SoC
     driver to access regmaps. Add infrastructure for pin-bank retention
     control. Clean out the pin retention control from
     arch/arm/mach-exynos and arch/arm/mach-s5p and put it properly in
     the Samsung pin control driver(s).

Commit 279967a6 ("HID: rmi: Handle all Synaptics touchpads using hid-rmi")
unconditionally switches over handling of all Synaptics touchpads to hid-rmi
(to make use of extended features of the HW); in case CONFIG_HID_RMI is
disabled though this renders the touchpad unusable, as the

	HID_DEVICE(HID_BUS_ANY, HID_GROUP_RMI, HID_ANY_ID, HID_ANY_ID)

match doesn't exist and generic/multitouch doesn't bind to it either (due
to hid group mismatch).

Fix this by switching over to hid-rmi only if it has been actually built.

Pull device mapper updates from Mike Snitzer:

 - Fix dm-raid transient device failure processing and other smaller
   tweaks.

 - Add journal support to the DM raid target to close the 'write hole'
   on raid 4/5/6.

 - Fix dm-cache corruption, due to rounding bug, when cache exceeds 2TB.

 - Add 'metadata2' feature to dm-cache to separate the dirty bitset out
   from other cache metadata. This improves speed of shutting down a
   large cache device (which implies writing out dirty bits).

 - Fix a memory leak during dm-stats data structure destruction.

 - Fix a DM multipath round-robin path selector performance regression
   that was caused by less precise balancing across all paths.

 - Lastly, introduce a DM core fix for a long-standing DM snapshot
   deadlock that is rooted in the complexity of the device stack used in
   conjunction with block core maintaining bios on current->bio_list to
   manage recursion in generic_make_request(). A more comprehensive fix
   to block core (and its hook in the cpu scheduler) would be wonderful
   but this DM-specific fix is pragmatic considering how difficult it
   has been to make progress on a generic fix.

Pull block layer updates from Jens Axboe:

 - blk-mq scheduling framework from me and Omar, with a port of the
   deadline scheduler for this framework. A port of BFQ from Paolo is in
   the works, and should be ready for 4.12.

 - Various fixups and improvements to the above scheduling framework
   from Omar, Paolo, Bart, me, others.

 - Cleanup of the exported sysfs blk-mq data into debugfs, from Omar.
   This allows us to export more information that helps debug hangs or
   performance issues, without cluttering or abusing the sysfs API.

 - Fixes for the sbitmap code, the scalable bitmap code that was
   migrated from blk-mq, from Omar.

 - Removal of the BLOCK_PC support in struct request, and refactoring of
   carrying SCSI payloads in the block layer. This cleans up the code
   nicely, and enables us to kill the SCSI specific parts of struct
   request, shrinking it down nicely. From Christoph mainly, with help
   from Hannes.

 - Support for ranged discard requests and discard merging, also from
   Christoph.

 - Support for OPAL in the block layer, and for NVMe as well. Mainly
   from Scott Bauer, with fixes/updates from various others folks.

 - Error code fixup for gdrom from Christophe.

 - cciss pci irq allocation cleanup from Christoph.

 - Making the cdrom device operations read only, from Kees Cook.

 - Fixes for duplicate bdi registrations and bdi/queue life time
   problems from Jan and Dan.

 - Set of fixes and updates for lightnvm, from Matias and Javier.

 - A few fixes for nbd from Josef, using idr to name devices and a
   workqueue deadlock fix on receive. Also marks Josef as the current
   maintainer of nbd.

 - Fix from Josef, overwriting queue settings when the number of
   hardware queues is updated for a blk-mq device.

 - NVMe fix from Keith, ensuring that we don't repeatedly mark and IO
   aborted, if we didn't end up aborting it.

 - SG gap merging fix from Ming Lei for block.

 - Loop fix also from Ming, fixing a race and crash between setting loop
   status and IO.

 - Two block race fixes from Tahsin, fixing request list iteration and
   fixing a race between device registration and udev device add
   notifiations.

 - Double free fix from cgroup writeback, from Tejun.

 - Another double free fix in blkcg, from Hou Tao.

 - Partition overflow fix for EFI from Alden Tondettar.

Commit 004172bd ("sched/core: Remove unnecessary #include headers")
removed the inclusion of asm/paravirt.h which is used to get
declarations of paravirt_steal_rq_enabled and paravirt_steal_clock.

It is implicitly included on x86 but not on arm and arm64 breaking the
build if paravirtualization is used.  Since things from that header are
used directly fix the build by putting the direct inclusion back.

Pull GFS2 updates from Robert Peterson:
 "We've got eight GFS2 patches for this merge window:

   - Andy Price submitted a patch to make gfs2_write_full_page a static
     function.

   - Dan Carpenter submitted a patch to fix a ERR_PTR thinko.

  Three patches fix bugs related to deleting very large files, which
  cause GFS2 to run out of journal space:

   - The first one prevents GFS2 delete operation from requesting too
     much journal space.

   - The second one fixes a problem whereby GFS2 can hang because it
     wasn't taking journal space demand into its calculations.

   - The third one wakes up IO waiters when a flush is done to restart
     processes stuck waiting for journal space to become available.

  The final three patches are a performance improvement related to
  spin_lock contention between multiple writers:

   - The "tr_touched" variable was switched to a flag to be more atomic
     and eliminate the possibility of some races.

   - Function meta_lo_add was moved inline with its only caller to make
     the code more readable and efficient.

   - Contention on the gfs2_log_lock spinlock was greatly reduced by
     avoiding the lock altogether in cases where we don't really need
     it: buffers that already appear in the appropriate metadata list
     for the journal. Many thanks to Steve Whitehouse for the ideas and
     principles behind these patches"
