The On Chip Peripherals (OCP) device node is a simplified
representation of the AM33XX SoC interconnect. An OCP dev
node is already defined in the am33xx.dtsi Device Tree
source file included by am33xx based boards so there is
no need to redefine this on each board DT file.
Also, the OCP and IP modules directly connected to it are SoC
internal details that is better to keep outside of board files.

am33xx boards DTS include the am33xx.dtsi Device Tree
source file that already define a pinmux device node for
the AM33XX SoC Pin Multiplex.
Redefining this for each board makes the Device Tree files
harder to modify and maintain so let's just use what is
already defined in the included .dtsi file.

This matches the vendor 3.8.x configuration that is shipping
with the boards.
The LED layout is now:
USR0: heartbeat
USR1: mmc0 (micro-SD slot)
USR2: cpu0
USR3: mmc1 (eMMC)
The cpu0 triggers was put in between the mmc triggers to make
is easier to see where the disk activity is.

Populate uarts, timers, rtc, wdt, gpio, i2c, spi, cpsw & pwm nodes.
Reason for adding these nodes early - hwmod code required address
space of peripherals corresponding to these nodes (as address space
details are removed from hwmod database).
uart0, timers - 1 & 2 and synctimer were already present, so here the
remaining uarts & timers are added.
All properties as per the existing binding has been added for uart,
timer, rtc, wdt & gpio. Even though that was not the current scope
of work, felt adding those would reduce or require no effort later
to get these peripherals working.
For i2c, spi, cpsw & pwm - only the properties that were sure to be
correct has been added (main intention is to make hwmod happy and
avoid any later modification to here added properties).
While at it add "ti,hwmod" property to already existing nodes.

companion chip for power management needs: TWL6030/TWL6032.
Therefore there is a typical connection of PMIC to OMAP4 so we can
move it into separate .dtsi file and do not duplicate over
board-specific files.

- Allow sess_cmd_map allocation failure fallback to use vzalloc
- Fix COMPARE_AND_WRITE se_cmd->data_length bug with FILEIO backends
- Fixes for COMPARE_AND_WRITE callback recursive failure OOPs + non
zero scsi_status bug
- Make iscsi-target do acknowledgement tag release from RX context
- Setup iscsi-target with extra (cmdsn_depth / 2) percpu_ida tags
Also included is a iscsi-target patch CC'ed for v3.10+ that avoids
legacy wait_for_task=true release during fast-past StatSN
acknowledgement, and two other SRP target related patches that address
long-standing issues that are CC'ed for v3.3+.
Extra thanks to Thomas Glanzmann for his testing feedback with
COMPARE_AND_WRITE + EXTENDED_COPY VAAI logic"

1) The resume part of user space driven hibernation (s2disk) is now
broken after the change that moved the creation of memory bitmaps
to after the freezing of tasks, because I forgot that the resume
utility loaded the image before freezing tasks and needed the
bitmaps for that. The fix adds special handling for that case.
2) One of recent commits changed the export of acpi_bus_get_device()
to EXPORT_SYMBOL_GPL(), which was technically correct but broke
existing binary modules using that function including one in
particularly widespread use. Change it back to EXPORT_SYMBOL().
3) The intel_pstate driver sometimes fails to disable turbo if its
no_turbo sysfs attribute is set. Fix from Srinivas Pandruvada.
4) One of recent cpufreq fixes forgot to update a check in cpufreq-cpu0

Pull ACPI and power management fixes from Rafael Wysocki:
- The resume part of user space driven hibernation (s2disk) is now
broken after the change that moved the creation of memory bitmaps to
after the freezing of tasks, because I forgot that the resume utility
loaded the image before freezing tasks and needed the bitmaps for
that. The fix adds special handling for that case.
- One of recent commits changed the export of acpi_bus_get_device() to
EXPORT_SYMBOL_GPL(), which was technically correct but broke existing
binary modules using that function including one in particularly
widespread use. Change it back to EXPORT_SYMBOL().
- The intel_pstate driver sometimes fails to disable turbo if its
no_turbo sysfs attribute is set. Fix from Srinivas Pandruvada.
- One of recent cpufreq fixes forgot to update a check in cpufreq-cpu0
which still (incorrectly) treats non-NULL as non-error. Fix from
Philipp Zabel.
- The SPEAr cpufreq driver uses a wrong variable type in one place
preventing it from catching errors returned by one of the functions
called by it. Fix from Sachin Kamat.

Pull xfs bugfixes from Ben Myers:
"There are lockdep annotations for project quotas, a fix for dirent
dtype support on v4 filesystems, a fix for a memory leak in recovery,
and a fix for the build error that resulted from it. D'oh"
* tag 'xfs-for-linus-v3.12-rc4' of git://oss.sgi.com/xfs/xfs:
xfs: Use kmem_free() instead of free()
xfs: fix memory leak in xlog_recover_add_to_trans
xfs: dirent dtype presence is dependent on directory magic numbers
xfs: lockdep needs to know about 3 dquot-deep nesting
.. so get rid of it. The only indirect users were all the
avc_has_perm() callers which just expanded to have a zero flags
argument.
