027c71bbae Input: improve autorepeat initialization
Add new function input_enable_softrepeat() that allows drivers to
initialize their own values for input_dev->rep[REP_DELAY] and
input_dev->rep[REP_PERIOD], but also use the software autorepeat
functionality from input.c.

For example, a HID driver could do:

static void xyz_input_configured(struct hid_device *hid,
                                 struct hid_input *hidinput)
{
        input_enable_softrepeat(hidinput->input, 400, 100);
}

static struct hid_driver xyz_driver = {
        .input_configured = xyz_input_configured,
}

1c5dd13459 input: i8042: Avoid resetting controller on system suspend/resume
If the upcoming system suspend is not going to be handled by the
platform firmware, like in the suspend-to-idle case, it is not
necessary to reset the controller in i8042_pm_suspend(), so avoid
doing that.

Moreover, if the system resume currently in progress has not been
started by the platform firmware, like in the suspend-to-idle case,
i8042_controller_resume() need not be called by i8042_pm_resume(),
so avoid doing that too in that case.

Additionally, try to catch the event that woke up the system by
calling the interrupt handler early during system resume if it has
not been started by the platform firmware.

When we initialize the driver/device, we really don't know how many
controllers are connected.  So send a "query presence" command to the

5ee8bda943 Input: xpad - x360w: report dpad as buttons and axes
as discussed here[0], x360w is the only pad that maps dpad_to_button.
This is bad for downstream developers as they have to differ between
x360 and x360w which is not intuitive.

This patch implements the suggested solution of exposing the dpad both
as axes and as buttons. This retains backward compatibility with software
already dealing with the difference while makes new software work as
expected across x360/ x360w pads.

a306a65f46 Input: xpad - remove needless bulk out URB used for LED setup
This code was probably wrong ever since and is redundant with
xpad_send_led_command. Both try to send a similar command to the xbox360
controller. However xpad_send_led_command correctly uses the pad_nr instead
of bInterfaceNumber to select the led and re-uses the irq_out URB instead
of creating a new one.

Note that this change only affects the two supported wireless controllers.
Tested using the xbox360 wireless controller (PC).

e3b651745a Input: xpad - use ida() for finding the pad_nr
The pad_nr corresponds to the lit up LED on the controller. Therefore there
should be no gaps when enumerating. Currently a LED is only re-assigned
after a controller is re-connected 4 times.

This patch uses ida to track connected pads - this way we can re-assign
freed up pad number immediately.

Consider the following case:
1. pad A is connected and gets pad_nr = 0
2. pad B is connected and gets pad_nr = 1
3. pad A is disconnected
4. pad A is connected again

using ida_simple_get() controller A now correctly gets pad_nr = 0 again.

879f2fea8a Input: ads7846 - correct the value got from SPI
According to the touch controller spec, SPI return a 16 bit value, only 12
bits are valid, they are bit[14-3].

The value of MISO and MOSI can be configured when SPI is in idle mode.
Currently this touch driver assumes the SPI bus sets the MOSI and MISO in
low level when SPI bus is in idle mode. So the bit[15] of the value got
from SPI bus is always 0. But when SPI bus congfigures the MOSI and MISO in
high level during the SPI idle mode, the bit[15] of the value get from SPI
is always 1. If bit[15] is not masked, we may get the wrong value.

Mask the invalid bit to make sure the correct value gets returned.
Regardless of the SPI bus idle configuration.

Commit 5702222c9a ("Input: joydev - use memdup_user() to duplicate
memory from user-space") changed the kmalloc() and copy_from_user()
with a single call to memdup_user() but wrongly used the same error
path than the old code in which the buffer allocated by kmalloc() was
freed if copy_from_user() failed.

This is of course wrong since if memdup_user() fails, no memory was
allocated and the error in the error-valued pointer should be returned.

a27b5e0a78 Input: add DA9062 OnKey capability to DA9063 OnKey driver
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

The data race happens on ps2dev->cmdcnt and ps2dev->cmdbuf contents.
__ps2_command reads that data concurrently with the interrupt handler. As
the result, for example, if a response arrives just after the timeout,
__ps2_command can copy out garbage from ps2dev->cmdbuf but then see that
ps2dev->cmdcnt is 0 and return success.

Stop the interrupt handler with serio_pause_rx() before reading the
results.

0df4f266b3 xen: Use correctly the Xen memory terminologies
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.

f5d75341fa Input: i8042 - lower log level for "no controller" message
Nowadays the machines without i8042 controller is popular, and no need
to print "No controller found" message in the error log level, which
annoys at booting in quiet mode.  Let's lower it info level.

abebcdfb64 sound updates for 4.3-rc1
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
 the end.
 
 Below are the highlights:
 
 Common:
 - Factoring out of AC'97 reset code from ASoC into the core helper
 - A few regmap API extensions (in case it's not pulled yet)
 
 ASoC:
 - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
   RT298 and ST STI controllers
 - Machine drivers for Rockchip systems with MAX98090 and RT5645 and
   RT5650
 - 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
 - ELD notifier implenetation for Intel HDMI/DP

eb38f3a4f6 Input: evdev - do not report errors form flush()
We've got bug reports showing the old systemd-logind (at least
system-210) aborting unexpectedly, and this turned out to be because
of an invalid error code from close() call to evdev devices.  close()
is supposed to return only either EINTR or EBADFD, while the device
returned ENODEV.  logind was overreacting to it and decided to kill
itself when an unexpected error code was received.  What a tragedy.

The bad error code comes from flush fops, and actually evdev_flush()
returns ENODEV when device is disconnected or client's access to it is
revoked. But in these cases the fact that flush did not actually happen is
not an error, but rather normal behavior. For non-disconnected devices
result of flush is also not that interesting as there is no potential of
data loss and even if it fails application has no way of handling the
error. Because of that we are better off always returning success from
evdev_flush().

Also returning EINTR from flush()/close() is discouraged (as it is not
clear how application should handle this error), so let's stop taking
evdev->mutex interruptibly.

 "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().

   - IRQ cleanups by Thomas Gleixner.

   - migrate to new 'set-state' interface.

   - random small cleanups"

832f5dacfa MIPS: Remove all the uses of custom gpio.h
Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS
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.

Pull x86 asm changes from Ingo Molnar:
 "The biggest changes in this cycle were:

   - Revamp, simplify (and in some cases fix) Time Stamp Counter (TSC)
     primitives.  (Andy Lutomirski)

   - Add new, comprehensible entry and exit handlers written in C.
     (Andy Lutomirski)

   - vm86 mode cleanups and fixes.  (Brian Gerst)

   - 32-bit compat code cleanups.  (Brian Gerst)

  The amount of simplification in low level assembly code is already
  palpable:

     arch/x86/entry/entry_32.S                          | 130 +----
     arch/x86/entry/entry_64.S                          | 197 ++-----

  but more simplifications are planned.

  There's also the usual laudry mix of low level changes - see the
  changelog for details"

d6f5aef298 Input: max8997_haptic - fix module alias
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.
