We rely on the result of scanning PNP bus for keyboard and mouse devices to
decide whether we should continue initialization of i8042 driver or not, so
the probes can not be asynchronous.
Also, it is not a good idea to unbind either of the PNP devices while i8042
is running, so let's disable bind/unbind for the PNP drivers through sysfs
and rely on i8042 cleaning after itself properly. User can still unbind and
rebind entire i8042 and that will take care of PNP drivers as well.

The Schenker XMG C504 is a rebranded Gigabyte P35 v2 laptop.
Therefore it also needs a keyboard reset to detect the Elantech touchpad.
Otherwise the touchpad appears to be dead.

Sync up with mainline to bring in I2C host notify changes and other
updates.
On suspend/resume cycle, selftest is executed to reset i8042 controller.
But when this is done in Asus devices, subsequent calls to detect/init
functions to elantech driver fails. Skipping selftest fixes this problem.
An easier step to reproduce this problem is adding i8042.reset=1 as a
kernel parameter. On Asus laptops, it'll make the system to start with the
touchpad already stuck, since psmouse_probe forcibly calls the selftest
function.
This patch was inspired by John Hiesey's change[1], but, since this problem
affects a lot of models of Asus, let's avoid running selftests on them.

The Pulse-Eight USB CEC adapter is a usb device that shows up as a ttyACM0
device. It requires that you run inputattach in order to communicate with
it via serio.
This all works well, but it would be nice to have a udev rule to
automatically start inputattach. That too works OK, but the problem comes
when the USB device is unplugged: the tty hangup is never handled by the
serio framework so the inputattach utility never exits and you have to kill
it manually.
By adding this hangup callback the inputattach utility now properly exits
as soon as the USB device is unplugged.
The udev rule I used on my Debian sid system is:
SUBSYSTEM=="tty", KERNEL=="ttyACM[0-9]*", ATTRS{idVendor}=="2548", ATTRS{idProduct}=="1002", ACTION=="add", TAG+="systemd", ENV{SYSTEMD_WANTS}+="pulse8-cec-inputattach@%k.service"
And /etc/systemd/system/pulse8-cec-inputattach@.service is as follows:
===============================================================
[Unit]
Description=inputattach for pulse8-cec device on %I

As explained in 1407814240-4275-1-git-send-email-decui@microsoft.com we
have a hard load dependency between i8042 and atkbd which prevents
keyboard from working on Gen2 Hyper-V VMs.
> hyperv_keyboard invokes serio_interrupt(), which needs a valid serio
> driver like atkbd.c. atkbd.c depends on libps2.c because it invokes
> ps2_command(). libps2.c depends on i8042.c because it invokes
> i8042_check_port_owner(). As a result, hyperv_keyboard actually
> depends on i8042.c.
>
> For a Generation 2 Hyper-V VM (meaning no i8042 device emulated), if a
> Linux VM (like Arch Linux) happens to configure CONFIG_SERIO_I8042=m
> rather than =y, atkbd.ko can't load because i8042.ko can't load(due to
> no i8042 device emulated) and finally hyperv_keyboard can't work and
> the user can't input: https://bugs.archlinux.org/task/39820
> (Ubuntu/RHEL/SUSE aren't affected since they use CONFIG_SERIO_I8042=y)
To break the dependency we move away from using i8042_check_port_owner()
and instead allow serio port owner specify a mutex that clients should use
to serialize PS/2 command stream.

Debugging input devices, specifically laptop touchpads, can be tricky
without having the physical device handy. Here we try to remedy that
with userio. This module allows an application to connect to a character
device provided by the kernel, and emulate any serio device. In
combination with userspace programs that can record PS/2 devices and
replay them through the /dev/userio device, this allows developers to
debug driver issues on the PS/2 level with devices simply by requesting
a recording from the user experiencing the issue without having to have
the physical hardware in front of them.

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

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

On some laptops, keyboard needs to be reset in order to successfully detect
touchpad (e.g., some Gigabyte laptop models with Elantech touchpads).
Without resettin keyboard touchpad pretends to be completely dead.
Based on the original patch by Mateusz Jończyk this version has been
expanded to include DMI based detection & application of the fix
automatically on the affected models of laptops. This has been confirmed to
fix problem by three users already on three different models of laptops.

This reverts commit 68da166491.
It turns out that the assertion about scope of regressions due to
always keeping keyboard controller in legacy mode was proven wrong.
There are laptops, such as Clevo W650SH, that only have internal
touchpad (no external PS/2 ports), that require active multiplexing
mode to switch the touchpad (Elantech) into native mode instead of
basic PS/2 emulation.

Active multiplexing is a nice feature as it allows several pointing devices
(such as touchpad and external mouse) use their native protocols at the
same time. Unfortunately many manufacturers do not implement the feature
properly even though they advertise it. The problematic implementations are
never fixed, since Windows by default does not use this mode, and move from
one BIOS/model of laptop to another. When active multiplexing is broken
turning it on usually results in touchpad, keyboard, or both unresponsive.
With PS/2 usage on decline (most of PS/2 devices in use nowadays are
internal laptop touchpads), I expect number of users who have laptops with
working MUX implementation, docking stations with external PS/2 ports, and
who are still using external PS/2 mice, to be rather small. Let's flip the
default to be OFF and allow activating it through i8042.nomux=0 kernel
option. We'll also keep DMI table where we can record known good models.

serio devices exposed via platform firmware interfaces such as ACPI may
provide additional identifying information of use to userspace.
We don't associate the serio devices with the firmware device (we don't
set it as parent), so there's no way for userspace to make use of this
information.
We cannot change the parent for serio devices instantiated though a
firmware interface as that would break suspend / resume ordering.
Therefore this patch adds a new firmware_id sysfs attribute so that
userspace can get a string from there with any additional identifying
information the firmware interface may provide.

"DeviceTree updates for 3.13. This is a bit larger pull request than
usual for this cycle with lots of clean-up.
- Cross arch clean-up and consolidation of early DT scanning code.
- Clean-up and removal of arch prom.h headers. Makes arch specific
prom.h optional on all but Sparc.
- Addition of interrupts-extended property for devices connected to
multiple interrupt controllers.

This branch contains code cleanups, moves and removals for 3.13.
Qualcomm msm targets had a bunch of code removal for legacy non-DT
platforms. Nomadik saw more device tree conversions and cleanup of old
code. Tegra has some code refactoring, etc.
One longish patch series from Sebastian Hasselbarth changes the init_time
hooks and tries to use a generic implementation for most platforms,
since they were all doing more or less the same things.
Finally the "shark" platform is removed in this release. It's been
abandoned for a while and nobody seems to care enough to keep it
around. If someone comes along and wants to resurrect it, the removal
can easily be reverted and code brought back.
Beyond this, mostly a bunch of removals of stale content across the
board, etc.

Here's the big driver core / sysfs update for 3.13-rc1.
There's lots of dev_groups updates for different subsystems, as they all
get slowly migrated over to the safe versions of the attribute groups
(removing userspace races with the creation of the sysfs files.) Also
in here are some kobject updates, devres expansions, and the first round
of Tejun's sysfs reworking to enable it to be used by other subsystems
as a backend for an in-kernel filesystem.
All of these have been in linux-next for a while with no reported

There is plenty of consumer hardware (e.g., mac books) that does not use AT
keyboards or PS/2 mice. It therefore makes sense for distro kernels to
build the related drivers as modules to avoid loading them on hardware that
does not need them. As such, these options should no longer be protected by
EXPERT.
Moreover, building these drivers as modules gets rid of the following ugly
error during boot:
[ 2.337745] i8042: PNP: No PS/2 controller found. Probing ports directly.

When 8042 internal data buffer is full, the driver
erroneously decides that the controller is not present.
i8042_flush returns the number of flushed bytes, which is
in 0 - I8042_BUFFER_SIZE range inclusive. Therefore, i8042_flush
has no way to indicate an error. Moreover i8042_controller_check
takes initially full buffer (i8042_flush returned
I8042_BUFFER_SIZE) as a sign of absence of the controller.
Let's change i8042 to return success/error instead and make sure
we do not return error prematurely.

Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=16004
Registers 'IdeaPad Slidebar' input device and
/sys/devices/platform/ideapad_slidebar/slidebar_mode
for switching slidebar's modes.
Now works on:
IdeaPad Y550, Y550P.
May work on (testing and adding new models is needed):

Remove unneeded error handling on the result of a call to
platform_get_resource when the value is passed to devm_ioremap_resource.
Move the call to platform_get_resource adjacent to the call to
devm_ioremap_resource to make the connection between them more clear.
A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression pdev,res,n,e,e1;
expression ret != 0;

The OLPC XO-1.75 and XO-4 laptops include a PS/2 touchpad and an AT
keyboard, yet they do not have a hardware PS/2 controller. Instead, a
firmware runs on a dedicated core ("Security Processor", part of the SoC)
that acts as a PS/2 controller through bit-banging.
Communication between the main cpu (Application Processor) and the
Security Processor happens via a standard command mechanism implemented
by the SoC. Add a driver for this interface to enable keyboard/mouse
input on this platform.

Use the newly introduced devm_ioremap_resource() instead of

The option allows you to remove TTY and compile without errors. This
saves space on systems that won't support TTY interfaces anyway.
bloat-o-meter output is below.
The bulk of this patch consists of Kconfig changes adding "depends on
TTY" to various serial devices and similar drivers that require the TTY
layer. Ideally, these dependencies would occur on a common intermediate
symbol such as SERIO, but most drivers "select SERIO" rather than
"depends on SERIO", and "select" does not respect dependencies.

They all define their chassis type as "Other" and therefore are not
categorized as "laptops" by the driver, which tries to perform AUX IRQ
delivery test which fails and causes touchpad not working.

With the changes in the random tree, IRQF_SAMPLE_RANDOM is now a
no-op; interrupt randomness is now collected unconditionally in a very
low-overhead fashion; see commit 775f4b297b. The IRQF_SAMPLE_RANDOM
flag was scheduled to be removed in 2009 on the
feature-removal-schedule, so this patch is preparation for the final
removal of this flag.

When copy_to/from_user fails in the middle of transfer we should not
report to the user that read/write partially succeeded but rather
report -EFAULT right away, so that application will know that it got
its buffers all wrong.
If application messed up its buffers we can't trust the data fetched
from userspace and successfully written to the device or if data read
from the device and transferred to userspace ended up where application
expected it to end.
If serio_write() fails we still going to report partial writes if failure
happens in the middle of the transfer.
This is basically a revert of 7a0a27d2ce
and 4fa0771138.

Avoid calling wait_event_interruptible() if client requested non-blocking
read, since it is not guaranteed that another thread will not consume
event after we checked if serio_raw->head != serio_raw->tail.
Also ensure we do not return 0 but keep waiting instead in blocking case,
when another thread steals "our" byte.

'struct serio' is a refcounted data structure with lifetime rules different
from 'struct xps2data'. It is quite likely that serio_unregister_port() will
try to free memory allocated by the port and that is why it should be
allocated separately.
Also switch to using platform_get/set_drvdata instead of dev_get/set_drvdata
because we are dealing with platform device.

Merge tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system
Pull "Disintegrate and delete asm/system.h" from David Howells:
"Here are a bunch of patches to disintegrate asm/system.h into a set of
separate bits to relieve the problem of circular inclusion
dependencies.
I've built all the working defconfigs from all the arches that I can
and made sure that they don't break.
The reason for these patches is that I recently encountered a circular
dependency problem that came about when I produced some patches to
optimise get_order() by rewriting it to use ilog2().
This uses bitops - and on the SH arch asm/bitops.h drags in
asm-generic/get_order.h by a circuituous route involving asm/system.h.
The main difficulty seems to be asm/system.h. It holds a number of
low level bits with no/few dependencies that are commonly used (eg.
memory barriers) and a number of bits with more dependencies that
aren't used in many places (eg. switch_to()).
These patches break asm/system.h up into the following core pieces:
(1) asm/barrier.h
Move memory barriers here. This already done for MIPS and Alpha.
(2) asm/switch_to.h
Move switch_to() and related stuff here.
(3) asm/exec.h
Move arch_align_stack() here. Other process execution related bits
could perhaps go here from asm/processor.h.
(4) asm/cmpxchg.h
Move xchg() and cmpxchg() here as they're full word atomic ops and
frequently used by atomic_xchg() and atomic_cmpxchg().
(5) asm/bug.h
Move die() and related bits.
(6) asm/auxvec.h
Move AT_VECTOR_SIZE_ARCH here.
Other arch headers are created as needed on a per-arch basis."
Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that. We'll find out anything that got broken and fix it..

Pull ARM platform updates from Russell King:
"This covers platform stuff for platforms I have a direct interest in
(iow, I have the hardware). Essentially:
- as we no longer support any other Acorn platforms other than RiscPC
anymore, we can collect all that code into mach-rpc.
- convert Acorn expansion card stuff to use IRQ allocation functions,
and get rid of NO_IRQ from there.
- cleanups to the ebsa110 platform to move some private stuff out of
its header files.
- large amount of SA11x0 updates:
- conversion of private DMA implementation to DMA engine support
(this actually gives us greater flexibility in drivers over the old
API.)
- re-worked ucb1x00 updates - convert to genirq, remove sa11x0
dependencies, fix various minor issues
- move platform specific sa11x0 framebuffer data into platform files
in arch/arm instead of keeping this in the driver itself
- update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
for SIR transmissions as well as FIR
- rework sa1111 support for genirq, and irq allocation
- fix sa1111 IRQ support so it works again
- use sparse IRQ support
After this, I have one more pull request remaining from my current
set, which I think is going to be the most problematical as it
generates 8 conflicts."

As part of the removal of get_driver()/put_driver(), this patch
(as1510) changes driver_find(); it now drops the reference it acquires
before returning. The patch also adjusts all the callers of
driver_find() to remove the now unnecessary calls to put_driver().
In addition, the patch adds a warning to driver_find(): Callers must
make sure the driver they are searching for does not get unloaded
while they are using it. This has always been the case; driver_find()
has never prevented a driver from being unregistered or unloaded.
Hence the patch will not introduce any new bugs. The existing callers
all seem to be okay in this respect, however I don't understand the
video drivers well enough to be certain about them.
