Pull mailbox framework from Jassi Brar:
"A framework for Mailbox controllers and clients have been cooking for
more than a year now.Everybody in the CC list had been copied on patchset revisions and
most of them have made sounds of approval, though just one concrete
Reviewed-by. The patchset has also been in linux-next for a couple of
weeks now and no conflict has been reported. The framework has the
backing of at least 5 platforms, though I can't say if/when they
upstream their drivers (some businesses have 'changed')"(Further acked-by by Arnd Bergmann and Suman Anna in the pull request
thread)* 'mailbox-for-linus' of git://git.linaro.org/landing-teams/working/fujitsu/integration:
dt: mailbox: add generic bindings
doc: add documentation for mailbox framework
mailbox: Introduce framework for mailbox
mailbox: rename pl320-ipc specific mailbox.h

The patch 30058677 "ARM / highbank: add support for pl320 IPC"
added a pl320 IPC specific header file as a generic mailbox.h.
This file has been renamed appropriately to allow the
introduction of the generic mailbox API framework.Acked-by: Mark Langsdorf

The naming convention of this driver was always under the scanner, people
complained that it should have a more generic name than cpu0, as it manages all
CPUs that are sharing clock lines.Also, in future it will be modified to support any number of clusters with
separate clock/voltage lines.Lets rename it to 'cpufreq_dt' from 'cpufreq_cpu0'.

Calxeda's new ECX-2000 part uses the same cpufreq interface as highbank,
so add it to the driver's compatibility list.This is a minor change that can safely be applied to the 3.10 and 3.11
stable trees.Signed-off-by: Mark Langsdorf

Now that the cpu device registration initialises the of_node(if available)
appropriately for all the cpus, parsing here is redundant.This patch removes all DT parsing and uses cpu->of_node instead.

As uninitialized array members will be initialized to zero, we can
avoid using a for loop by setting a value to it.Signed-off-by: Emilio López

As multiplatform build is being adopted by more and more ARM platforms,
initcall function should be used very carefully. For example, when
GENERIC_CPUFREQ_CPU0 is built in the kernel, cpu0_cpufreq_driver_init()
will be called on all the platforms to initialize cpufreq-cpu0 driver.To eliminate this undesired the effect, the patch changes cpufreq-cpu0
driver to have it instantiated as a platform_driver. Then it will only
run on platforms that create the platform_device "cpufreq-cpu0".Along with the change, it also changes cpu_dev to be &pdev->dev,
so that managed functions can start working, and module build gets
supported too.The highbank-cpufreq driver is also updated accordingly to adapt the
changes on cpufreq-cpu0.Signed-off-by: Shawn Guo

Highbank processors depend on the external ECME to perform voltage
management based on a requested frequency. Communication between the
A9 cores and the ECME happens over the pl320 IPC channel.Signed-off-by: Mark Langsdorf
