71daf89476 Input: mma8450 - add parent device
Add the parent device so that udev can show the full hierarchy. This avoids
the device showing up under /devices/virtual/input instead of the i2c bus
it is actually attached to.

Newer Blackfin boards use pinctrl API to manage pins and the legacy

7694f44d63 Input: bfin_rotary - fix potential oops in interrupt handler
The interrupt handler in the driver tries to fetch driver data from
platform device, unfortunately it is only set up after interrupt handler
is registered. Since interrupt handler does not really need to access
the platform device itself let's change it to get the driver data
instance instead.

791738be57 Input: soc_button_array - use "Windows" key for "Home"
KEY_HOME is the key to go back to the beginning of the line, not the key to
get into an overview mode, as Windows does. GNOME can already make use of
the Windows key on multiple form factors, and other desktop environments
can use it depending on the form factor.

Using "Windows" as the emitted key also means that the keycode sent out
matches the symbol on the key itself.

So switch KEY_HOME to KEY_LEFTMETA ("Windows" key).

Chang Huaixin
4d544e3bdb Input: xen-kbdfront - free grant table entry in xenkbd_disconnect_backend
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.

95afae4814 xen: remove DEFINE_XENBUS_DRIVER() macro
The DEFINE_XENBUS_DRIVER() macro looks a bit weird and causes sparse
errors.

Replace the uses with standard structure definitions instead.  This is
similar to pci and usb device registration.

042e1c7916 Input: soc_button_array - convert to platform bus
ACPI device enumeration mechanism changed a lot since 3.16-rc1.
ACPI device objects with _HID will be enumerated to platform bus by default.
For the existing PNP drivers that probe the PNPACPI devices, the device ids
are listed explicitly in drivers/acpi/acpi_pnp.c.
But ACPI folks will continue their effort on shrinking this id list by
converting the PNP drivers to platform drivers, for the devices that don't
belong to PNP bus in nature.

Reports:

Palmas power button just needs threaded IRQ handler since I2C operations
are involved and there is nothing in non-threaded primary handler we could
do.

So mark the request with ONESHOT as it should have been done in these
cases.

adff5962fd Input: introduce palmas-pwrbutton
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.

Adding support for the DRV2667 haptic driver.  This device has the ability
to store vibration patterns in RAM and execute them once the GO bit is set.

The initial driver sets a basic waveform in the first waveform sequence and
will play the waveform when the GO bit is set and will continously play the
waveform until the GO bit is unset.
