- evdev users can now limit or mask the kind of events they will
receive. This will allow applications such as power manager or
network manager to only be woken when user presses special keys
such as KEY_POWER or KEY_WIFI and not be bothered with ordinary
key presses coming from keyboard

hp_sdc_rtc_proc_show() use timeval to store the time, which will overflow
in 2038.
This patch fixes this problem by replacing timeval with timespec64.
hp_sdc_rtc_proc_show() only output string, so that userspace will work
normally if we apply this patch.
Not all timer in i8042 have y2038 risk(handshake, match timer, etc),

Some encoders have both outputs low in stable states, others also have
a stable state with both outputs high (half-period mode) and some have
a stable state in all steps (quarter-period mode). The driver used to
support the former states and with this change it can also support the
later.
This commit also deprecates the 'half-period' property and introduces
a new property 'steps-per-period'. This property specifies the
number of steps (stable states) produced by the rotary encoder
for each GPIO period.

Add DA9062 OnKey support into the existing DA9063 OnKey driver component by
using generic access tables for common register and bit mask definitions.
The following change will add generic register and bit mask support to the
DA9063 OnKey.
The following alterations have been made to the DA9063 OnKey:
- Addition of a da906x_chip_config structure to hold all
generic registers and bitmasks for this type of OnKey component.
- Addition of an struct of_device_id table for DA9063 and DA9062
defaults
- Refactoring functions to use struct da9063_onkey accesses to generic
registers/masks instead of using defines from registers.h
- Re-work of da9063_onkey_probe() to use of_match_node() and
dev_get_regmap() to provide initialisation of generic registers and
masks and access to regmap

Merge tag 'for-linus-4.3-rc0b-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip

"Use the correct GFN/BFN terms more consistently"
* tag 'for-linus-4.3-rc0b-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
xen/xenbus: Rename the variable xen_store_mfn to xen_store_gfn
xen/privcmd: Further s/MFN/GFN/ clean-up
hvc/xen: Further s/MFN/GFN clean-up
video/xen-fbfront: Further s/MFN/GFN clean-up

xen: Use correctly the Xen memory terminologies
arm/xen: implement correctly pfn_to_mfn
xen: Make clear that swiotlb and biomerge are dealing with DMA address
Based on include/xen/mm.h [1], Linux is mistakenly using MFN when GFN
is meant, I suspect this is because the first support for Xen was for
PV. This resulted in some misimplementation of helpers on ARM and
confused developers about the expected behavior.
For instance, with pfn_to_mfn, we expect to get an MFN based on the name.
Although, if we look at the implementation on x86, it's returning a GFN.
For clarity and avoid new confusion, replace any reference to mfn with
gfn in any helpers used by PV drivers. The x86 code will still keep some
reference of pfn_to_mfn which may be used by all kind of guests
No changes as been made in the hypercall field, even
though they may be invalid, in order to keep the same as the defintion
in xen repo.
Note that page_to_mfn has been renamed to xen_page_to_gfn to avoid a
name to close to the KVM function gfn_to_page.
Take also the opportunity to simplify simple construction such
as pfn_to_mfn(page_to_pfn(page)) into xen_page_to_gfn. More complex clean up
will come in follow-up patches.

There are little changes in core part, but lots of development are
found in drivers, especially ASoC. The diffstat shows regmap-
related changes for a slight API additions / changes, and that's all.
Looking at the code size statistics, the most significant addition
is for Intel Skylake. (Note that SKL support is still underway, the
codec driver is missing.) Also STI controller driver is a major
addition as well as a few new codec drivers.
In HD-audio side, there are fewer changes than the past. The
noticeable change is the support of ELD notification from i915
graphics driver. Thus this pull request carries a few changes in
drm/i915.
Other than that, USB-audio got a rewrite of runtime PM code. It
was initiated by lockdep warning, but resulted in a good cleanup in

Below are the highlights:
Common:
- Factoring out of AC'97 reset code from ASoC into the core helper

ASoC:

- Initial driver support for Intel Skylake devices
- Lots of rsnd cleanup and enhancements
- A few DAPM fixes and cleanups
- A large number of cleanups in various drivers (conversion and
standardized to regmap, component) mostly by Lars-Peter and Axel
HD-audio:
- Extended HD-audio core for Intel Skylake controller support
- Quirks for Dell headsets, Alienware 15
- Clean up of pin-based quirk tables for Realtek codecs

"This is the main pull request for 4.3 for MIPS. Here's the summary:
Three fixes that didn't make 4.2-stable:
- a -Os build might compile the kernel using the MIPS16 instruction
set but the R2 optimized inline functions in <uapi/asm/swab.h> are
implemented using 32-bit wide instructions which is invalid.
- a build error in pgtable-bits.h for a particular kernel
configuration.
- accessing registers of the CM GCR might have been compiled to use
64 bit accesses but these registers are onl 32 bit wide.
And also a few new bits:
- move the ATH79 GPIO driver to drivers/gpio
- the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h,
change ATH79 accordingly.
- fix definition of pgprot_writecombine
- add an implementation of dma_map_ops.mmap
- fix alignment of quiet build output for vmlinuz link
- BCM47xx: Use kmemdup rather than duplicating its implementation
- Netlogic: Fix 0x0x prefixes of constants.
- merge Bjorn Helgaas' series to remove most of the weak keywords
from function declarations.
- CP0 and CP1 registers are best considered treated as unsigned
values to avoid large values from becoming negative values.
- improve support for the MIPS GIC timer.
- enable common clock framework for Malta and SEAD3.
- a number of improvments and fixes to dump_tlb().
- document the MIPS TLB dump functionality in Magic SysRq.
- Cavium Octeon CN68XX improvments.
- NetLogic improvments.
- irq: Use access helper irq_data_get_affinity_mask.
- handle MSA unaligned accesses.
- a number of R6-related math-emu fixes.
- support for I6400.
- improvments to MSA support.
- add uprobes support.
- move from deprecated __initcall to arch_initcall.
- remove finish_arch_switch().

machines, and each machine type provides its own gpio.h. However
only a handful really implement the GPIO API, most just forward
everythings to gpiolib.
The Alchemy machine is notable as it provides a system to allow
implementing the GPIO API at the board level. But it is not used by
any board currently supported, so it can also be removed.
For most machine types we can just remove the custom gpio.h, as well
as the custom wrappers if some exists. Some of the code found in
the wrappers must be moved to the respective GPIO driver.
A few more fixes are need in some drivers as they rely on linux/gpio.h
to provides some machine specific definitions, or used asm/gpio.h
instead of linux/gpio.h for the gpio API.

The driver is a platform driver and not a I2C driver so its modalias
should be exported with MODULE_DEVICE_TABLE(platform,...) instead of
MODULE_DEVICE_TABLE(i2c,...).
Also, remove the unnecessary MODULE_ALIAS("platform:max8997-haptic")
now that the correct module alias is created.

The Maxim 77843 haptic driver differs from 77693 by:
1. Setting the bias.
2. Different configuration register.
3. Not enabling the low-sys DAC.
4. Using same regmap for PMIC and haptic blocks.
Incorporate all differences into max77693 haptic driver so both devices
can be supported.

Storing a predefined PWM divisor in state container structure is
meaningless. The field, after initialization, is only read so this only
obfuscates the code. Remove the field and use directly enum value.

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.
Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
appropriate.

The I2C core always reports the MODALIAS uevent as "i2c:<client name"
regardless if the driver was matched using the I2C id_table or the
of_match_table. So the driver needs to export the I2C table and this
be built into the module or udev won't have the necessary information
to auto load the correct module when the device is added.

On pm8xxx PMICs, shutdown and restart are signaled to the PMIC via a pin
called PS_HOLD. When this pin goes low, the PMIC performs a configurable
power sequence. Add a .shutdown hook so that we can properly configure this
power sequence for shutdown or restart depending on the system state.

Separate the functionality using sequences of register writes from the
functions that take register defaults. This change renames the arguments
in order to support the extension of reg_sequence to take an optional
delay to be applied after any given register in a sequence is written.
This avoids adding an int to all register defaults, which could
substantially increase memory usage for regmaps with large default tables.
This also updates all the clients of multi_reg_write/register_patch.
