the Windows key on multiple form factors, and other desktop environments

xenkbd_disconnect_backend doesn't free grant table entry. This bug affects
live migration.
xenkbd_disconnect_backend uses gnttab_end_foreign_access_ref to handle
grant table entry which doesn't really free an entry.
Thus every time we do xenkbd_resume, grant table entry increses by one. As
an grant table entry occupies 8 bytes, an grant table page has at most 512
entries. Every 512 times we do xenkdb_resume, grant table pages increses by
one.
After around 3500 times of live migration, grant table pages will increase
by 7, causing too many pages to populate and hitting max_pages limit when
assigning pages.Thus assign_pages will fail, so will live migration.

Many palmas family of PMICs have support for interrupt based power button.
This allows the device to notify the processor of external push button
events over the shared palmas interrupt. However, this event is generated
only during a "press" operation. Software is supposed to poll(sigh!) for
detecting a release event.
The PMIC also supports ability to power off independent of the software
decisions when the button is pressed for a long duration if the PMIC is
appropriately configured on the platform.
Even though the function is similar to twl4030_pwrbutton, it is
substantially different in operation to belong to a new driver of it's own.

Add the TI drv260x haptics/vibrator driver. This device uses the input
force feedback to produce a wave form to driver an ERM or LRA actuator
device.
The initial driver supports the devices real time playback mode. But the
device has additional wave patterns in ROM. This functionality will be
added in future patchsets.

The memory are mapped using of_ioremap() which is
an indication this is sbus memory.
Shift all uses of inb/outb to the sbus variants.
The inb/outb methods uses ASI_PHYS_BYPASS_EC_E_L,
whereas sbus_ variants uses ASI_PHYS_BYPASS_EC_E.
The difference is if the reads/writes are done in
native or little endian.
But for byte reads/writes there is no difference
so this does not matter for inb/outb - and this
driver only uses the byte variants.

If the debounce time is 0 our usage of ilog2() later on in this driver will
cause undefined behavior. If CONFIG_OF=n this fact is evident to the

this by setting a sane default for debounce and failing to probe if

Using platform_get_irq_byname() to retrieve the IRQ number returns the
VIRQ number rather than the local IRQ number for the device. Passing that
value then into regmap_irq_get_virq() causes a failure because the
function is expecting the local IRQ number (e.g. 0, 1, 2, 3, etc).
This patch removes use of regmap_irq_get_virq() to prevent this failure
from happening.

Merge tag 'dropmachtimexh-v2' of git://git.pengutronix.de/git/ukl/linux into next/cleanup
This cleanup series gets rid of <mach/timex.h> for platforms not using
ARCH_MULTIPLATFORM. (For multi-platform code it's already unused since
387798b (ARM: initial multiplatform support).)
To make this work some code out of arch/arm needed to be adapted. The
respective changes got acks by their maintainers to be taken via armsoc
(with Andrew Morton substituting for Alessandro Zummo as rtc maintainer).
Compared to the previous pull request there was another patch added that
fixes a (non-critical) regression on ixp4xx. Olof Johansson asked to not
squash this fix into the original commit to save him from the need to
reverify the series.

The wrong register bit of the DA9052/3 PMIC registers was
used to determine the status on the ONKEY.
Also a failure in reading the status register will no longer
result in the work queue being rescheduled as that would result
in a (potentially) endless retry.

This change adds a delayed_work to detect the release of onkey since HW will
not generate interrupt for it.
At the same time, we move the KEY event to POWER instead of SUSPEND, which
will be suitable for both Android and Linux. Userspace PowerManager Daemon
will decide to suspend or shutdown based on how long we have touched onkey.

Since the IRQ handler always returns IRQ_HANDLED it means this irq is not
a shared IRQ at all. Or at least, the SW is not self-consistent now.

We can control whetehr device generates interrupts or not so let's
implement open and close methods of input device so that we do not do any
processing until there are users.
