Haridhar Kalvala 7d3d88401f HID: google: Enable PM Full On mode when adjusting backlight
hammer LED backlight brightness is not getting set when USB
device is in suspend state.

This patch fixes the issue by requesting USB HID device to be
in FULLON mode, so that sending hardware output report and
hardware raw request won't fail to set brightness, and set
device back to NORMAL mode once this call returns.

Benjamin Tissoires 843e475f94 HID: multitouch: remove dead zones of Razer Blade Stealth
The Razer Blade Stealth detects palms too aggressively and this creates
a dead zone around the touchpad. Users like being able to use their
entire touchpad, so we should probably not filter out the "palm" events
from the device and report them as regular touches, leaving the palm
detection up to the upper stack

For mouse and joystick devices user can change the polling interval
via usbhid.mousepoll and usbhid.jspoll.
Implement the same thing for keyboards, so user can
reduce(or increase) input latency this way.

This has been tested with a Cooler Master Devastator with
kbpoll=32, resulting in delay between events of 32 ms(values were taken
from evtest).

Todd Kelner b7289cb1cf HID: sony: Add touchpad support for NSG-MR5U and NSG-MR7U remotes
Sony's NSG-MR5U and NSG-MR7U remote controls have a full keyboard and a
touchpad.  The keyboard is already supported by the existing Linux
kernel and drivers but the touchpad is not recognized.  This patch adds
the coded needed to bring full functionality to the touchpad.

Note that these remotes use the vendor code for SMK even though they are
Sony branded.

Known limitations
- The built-in accelerometers are not supported by these changes
- When the Drag (Fn) key is used as a mouse button, the button is
automatically released when the key begins repeating.  There are two
  workarounds for this 1) Use the button behind the touchpad instead of
  the Drag (Fn) key or 2) Disable the key repeat functionality or
  increase the key repeat delay.

Tomasz Kramkowski 79837eded6 HID: elecom: refer to trackballs by model name instead of series
This patch changes all references to ELECOM trackballs using their
series name to refer to them by their model name.

ELECOM provides multiple series of mice such as EX-G, HUGE, and DEFT.
Although it has not caused conflicts in the driver, there can be more
than one iteration of mice in each series. For example, there are 7
variants of EX-G trackballs but only three (M-XT3URBK, M-XT3DRBK, and
M-XT4DRBK) need a driver to work correctly.

There are also 4 DEFT series trackballs but two of them have the same
VID:PID as the other two. I picked the earlier model for the naming of
the PID macros.

Linus Torvalds 9798f5178f The is the bulk of GPIO changes for the v4.16 kernel cycle.
Core changes:
 
 - Disallow open drain and open source flags to be set
   simultaneously. This doesn't make electrical sense, and would
   the hardware actually respond to this setting, the result
   would be short circuit.
 
 - ACPI GPIO has a new core infrastructure for handling quirks.
   The quirks are there to deal with broken ACPI tables centrally
   instead of pushing the work to individual drivers. In the world
   of BIOS writers, the ACPI tables are perfect. Until they find a
   mistake in it. When such a mistake is found, we can patch it
   with a quirk. It should never happen, the problem is that it
   happens. So we accomodate for it.
 
 - Several documentation updates.
 
 - Revert the patch setting up initial direction state from
   reading the device. This was causing bad things for drivers
   that can't read status on all its pins. It is only affecting
   debugfs information quality.
 
 - Label descriptors with the device name if no explicit label is
   passed in.
 
 - Pave the ground for transitioning SPI and regulators to use
   GPIO descriptors by implementing some quirks in the device tree
   GPIO parsing code.
 
 New drivers:
 
 - New driver for the Access PCIe IDIO 24 family.
 
 Other:
 
 - Major refactorings and improvements to the GPIO mockup driver
   used for test and verification.
 
 - Moved the AXP209 driver over to pin control since it gained a
   pin control back-end. These patches will appear (with the same
   hashes) in the pin control pull request as well.
 
 - Convert the onewire GPIO driver w1-gpio to use descriptors.
   This is merged here since the W1 maintainers send very few
   pull requests and he ACKed it.
 
 - Start to clean up driver headers using <linux/gpio.h> to just
   use <linux/gpio/driver.h> as appropriate.

Linus Torvalds 2382dc9a3e dma mapping changes for Linux 4.16:
This pull requests contains a consolidation of the generic no-IOMMU code,
 a well as the glue code for swiotlb.  All the code is based on the x86
 implementation with hooks to allow all architectures that aren't cache
 coherent to use it.  The x86 conversion itself has been deferred because
 the x86 maintainers were a little busy in the last months.

Linus Torvalds 28bc6fb959 SCSI misc on 20180131
This is mostly updates of the usual driver suspects: arcmsr,
 scsi_debug, mpt3sas, lpfc, cxlflash, qla2xxx, aacraid, megaraid_sas,
 hisi_sas.  We also have a rework of the libsas hotplug handling to
 make it more robust, a slew of 32 bit time conversions and fixes, and
 a host of the usual minor updates and style changes.  The biggest
 potential for regressions is the libsas hotplug changes, but so far
 they seem stable under testing.

Linus Torvalds 0be600a5ad - DM core fixes to ensure that bio submission follows a depth-first tree
walk; this is critical to allow forward progress without the need to
   use the bioset's BIOSET_NEED_RESCUER.
 
 - Remove DM core's BIOSET_NEED_RESCUER based dm_offload infrastructure.
 
 - DM core cleanups and improvements to make bio-based DM more efficient
   (e.g. reduced memory footprint as well leveraging per-bio-data more).
 
 - Introduce new bio-based mode (DM_TYPE_NVME_BIO_BASED) that leverages
   the more direct IO submission path in the block layer; this mode is
   used by DM multipath and also optimizes targets like DM thin-pool that
   stack directly on NVMe data device.
 
 - DM multipath improvements to factor out legacy SCSI-only
   (e.g. scsi_dh) code paths to allow for more optimized support for NVMe
   multipath.
 
 - A fix for DM multipath path selectors (service-time and queue-length)
   to select paths in a more balanced way; largely academic but doesn't
   hurt.
 
 - Numerous DM raid target fixes and improvements.
 
 - Add a new DM "unstriped" target that enables Intel to workaround
   firmware limitations in some NVMe drives that are striped internally
   (this target also works when stacked above the DM "striped" target).
 
 - Various Documentation fixes and improvements.
 
 - Misc. cleanups and fixes across various DM infrastructure and targets
   (e.g. bufio, flakey, log-writes, snapshot).
