Commit 700a38b27e ("Input: gpio_keys - switch to using generic device
properties") switched to use generic device properties for GPIO keys and
commit 5feeca3c1e ("Input: gpio_keys - add support for GPIO descriptors")
switched from legacy GPIO numbers to GPIO descriptors.
Previously devm_gpio_request_one was explicitly passed GPIOF_DIR_IN flag
to set the GPIO direction as input. However devm_get_gpiod_from_child
doesn't have such provisions and hence fwnode_get_named_gpiod can't set
it as input.
This breaks few platforms with the following error:
" gpiochip_lock_as_irq: tried to flag a GPIO set as output for IRQ
unable to lock HW IRQ <n> for IRQ
genirq: Failed to request resources for POWER (irq <x>) on irqchip
gpio_keys: Unable to claim irq <x>; error -22
gpio-keys: probe failed with error -22 "
This patch fixes the issue by setting input direction explicitly for
gpio lines described by generic properties.

commit ef3714fdbc ("Input: bma150 - extend chip detection for bma180"),
adds bma180 chip-ids to the input bma150 driver, assuming that they are
100% compatible, but the bma180 is not compatible with the bma150 at all,
it has 14 bits resolution instead of 10, and it has quite different
control registers too.
Treating the bma180 as a bma150 wrt its data registers will just result
in throwing away the lowest 4 bits, which is not too bad. But the ctrl
registers are a different story. Things happen to just work but supporting
that certainly does not make treating the bma180 the same as the bma150
right.
Since some setups depend on the evdev interface the bma150 driver offers
on top of the bma180, we cannot simply remove the bma180 ids.
So this commit only removes the bma180 id when the bma180 iio driver,
which does treat the bma180 properly, is enabled.

Add binding information for DA9061 onkey.
This patch updates the compatible string "dlg,da9061-onkey" to support
DA9061, removes the reference to KEY_SLEEP (which the driver no longer
supports) and fixes a typo in the example for DA9063.
Supporting KEY_SLEEP was not the general convention and the typical
solution should have been for KEY_POWER to support both cases of suspend
and S/W power off. This change was sent to the DA9063 ONKEY device
driver in a separate patch, but the documentation was not updated at
that time.
- f889bea Report KEY_POWER instead of KEY_SLEEP during power key-press

Sync up with mainline to bring in I2C host notify changes and other

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.

When discovering the number of VPEs per core, smp_num_siblings will be
incorrect for kernels built without support for the MIPS MultiThreading
(MT) ASE running on systems which implement said ASE. This leads to
accesses to VPEs in secondary cores being performed incorrectly since
mips_cm_vp_id calculates the wrong ID to write to the local "other"
registers. Fix this by examining the number of VPEs in the core as
reported by the CM.
This patch presumes that the number of VPEs will be the same in each
core of the system. As this path only applies to systems with CM version
2.5 or lower, and this property is true of all such known systems, this
is likely to be fine but is described in a comment for good measure.

include/linux/property.h: fix typo/compile error
ocfs2: fix deadlock on mmapped page in ocfs2_write_begin_nolock()
mm: workingset: fix crash in shadow node shrinker caused by replace_page_cache_page()
This fixes commit d76eebfa17 ("include/linux/property.h: fix build
issues with gcc-4.4.4").
With that commit we get the following compile error when using the
PROPERTY_ENTRY_INTEGER_ARRAY macro.
include/linux/property.h:201:39: error: `u32_data' undeclared (first
use in this function)
PROPERTY_ENTRY_INTEGER_ARRAY(_name_, u32, _val_)
^
include/linux/property.h:193:17: note: in definition of macro
`PROPERTY_ENTRY_INTEGER_ARRAY'
{ .pointer = { _type_##_data = _val_ } }, \
^
This needs a '.' to reference the union member. It seems this was just
overlooked here since it is done correctly in similar constructs in
other parts of the original commit.
This fix is in preparation of upcoming commits that will use this macro.
