BAM DMUX driver gives the data to the USB in work context and USB
is once again scheduling work for sending the data to the host.
This change avoid's the double work queue scheduling for the data
received from BAM DMUX, which might reduce the cpu usage and improve
the throughputs.

* changes:
Input: atmel_mxt_ts: Add a debugfs attribute to show all objects
board: 8960: Add config data for mXT1386E touch controller
input: atmel_mxt_ts: Add support for object PROCI_SHIELDLESS_T56
input: atmel_mxt_ts: Support runtime selection of config data
The sysfs attribute show method (mxt_object_show) is limited to show
object information up to (PAGE_SIZE - 1) bytes. We need a way to get
the complete information of all objects. The object information can
be obtained from <debugfs-mount>/atmel_mxt_ts/object.

The mXT1386E touch controller supports a new signal processing object
PROCI_SHIELDLESS_T56. This object is both readable and writable.

Add support for dynamic configuration data update if the target can
support more than one Atmel chip. Platform data contains an array of
supported config data along with family ID, variant ID and firmware
version. Driver searches for matching family ID, variant ID and
firmware version, and uses the corresponding config data to program.

The memory where the sysfs attribute is stored on

An invalid value in the kernel address variable causes an
ion unmap error when attempting to clean up after a failure
occurs when importing the ion fd in the function
vidc_insert_addr_table().
When an ion import fd failure occurs, cleanup is not required.
During failure we now go directly to bail out and the cleanup
code is skipped.

Currently during boot, and every suspend and resume, we call
regulator_set_optimum_mode on every touchscreen regulator. However,
some regulators don't support this function, and this will cause
set_optimum_mode to print an error when this occurs. Correct this by
checking if it is valid to call set_optimum_mode on a given regulator
before doing so.

There is a possibility that 2 or more clients can use the same
channel, one as producer and the other(s) as sink.
The slim_query_ch API gives the ability for a client to specify
channel number it needs to use.
Reference counting is used to make sure channel is not deallocated
until the last caller deallocates it.
Another counter (def) is used to keep track of channel definition and
removal. Channel definition is sent to hardware when the producer
and/or consumer(s) connects ports to the channel. Channel is only
removed when all clients indicate they want to remove channel.

Add support for snapshotting the state of the GPU in a binary format. The
snapshot can be pulled from sysfs and parsed off-target. The advantage is
that far more information can be encapsulated in a snapshot then can be
printed on the console during a hang. Snapshots are automatically created
during a hang, or can be manually triggered by writing 'trigger'
in /sys/class/kgsl/kgsl-<n>/snapshot where n is either the 2D or 3D device.
Snapshot data can be pulled from 'dump' in the same directory.

until the RPM properly handles D0+CXO_CLK resources.

During subsystem restart, SMD_EVENT_CLOSE is sent via callback,
which the DUN and RMNET control modules mistakenly interpret as the
channel being closed automatically. This causes a problem when the
modem comes back online and notifies via SMD_EVENT_OPEN: the gadget
driver now has a handle to an open SMD channel even without a USB
connection. Then when the USB cable is reconnected, due to disconnect
being called first, it accidentally closes the re-opened channel,
causing the following smd_open() to fail because it is busy being
closed.
Instead, simply always call smd_close() on actual disconnect,
so that the subsequent connect will successfully be able to open the
channel.
