As stated in the introduction of the document, the families of ARM
SoCs at Marvell are very complicated, and it is difficult for
newcomers to understand the organization of this SoC family and how it
relates to the Linux kernel support for those hardware platforms.
This document is only at RFC stage for now, it requires reviews and
comments from the Marvell maintainers, the PXA maintainers and the MMP
maintainers. For correctness of course, but also to add any other
information that would be useful. For example, one of the thing that
wasn't clear how to detail in the documentation is how the SoCs relate
to each other in terms of hardware IP blocks. For example, most of the
Kirkwood/Dove/Armada 370-XP/etc. hardware IPs (I2C, SPI, USB, SATA,
etc.) are identical, while the PXA and MMP families are completely
separate.

Changes from v3:
* Add Arnd Bergmann Acked-by.
Changes from v2:
* Mention the plat-<foo> directory that each SoC family is using.
* Take into account Eric Miao's comments on the PXA/MMP families: add
PXA21x/PXA25x/PXA26x to the list, mention which processors are
AP+CP or AP only. Clarify the comments on which SoCs were designed
by Intel, which ones were designed by Marvell after the acquisition
of the XScale family.
* Mention long-term plans regarding the support of those SoC
families.
Changes from v1:
* Added publicly available datasheet for the 88F5182 pointed by
Andrew Lunn.
* Added publicly available datasheet for the 88F5281 found with
Google searches
* Mentionned the Feroceon core name where appropriate, and Sheeva
where appropriate
* Fixed the core names for PXA930, PXA935 and PXA955 after comments
from Arnd Bergmann. Wikipedia is mistakenly suggesting that PXA93x
are Sheeva-based, and there isn't much information available on the
web about the 955.

Pull ARM DMA engine updates from Russell King:
"This looks scary at first glance, but what it is is:
- a rework of the sa11x0 DMA engine driver merged during the previous
cycle, to extract a common set of helper functions for DMA engine
implementations.
- conversion of amba-pl08x.c to use these helper functions.
- addition of OMAP DMA engine driver (using these helper functions),
and conversion of some of the OMAP DMA users to use DMA engine.
Nothing in the helper functions is ARM specific, so I hope that other
implementations can consolidate some of their code by making use of
these helpers.
This has been sitting in linux-next most of the merge cycle, and has
been tested by several OMAP folk. I've tested it on sa11x0 platforms,
and given it my best shot on my broken platforms which have the
amba-pl08x controller.
The last point is the addition to feature-removal-schedule.txt, which
will have a merge conflict. Between myself and TI, we're planning to
remove the old TI DMA implementation next year."

raid5: reduce chance release_stripe() taking device_lock
In commit 3b6e2723f3 ("locks: prevent side-effects of
locks_release_private before file_lock is initialized") we removed the
last user of lm_release_private without removing the field itself.

Round of refactoring and enhancements to irq_domain infrastructure. This
series starts the process of simplifying irqdomain. The ultimate goal is
to merge LEGACY, LINEAR and TREE mappings into a single system, but had
to back off from that after some last minute bugs. Instead it mainly
reorganizes the code and ensures that the reverse map gets populated
when the irq is mapped instead of the first time it is looked up.
Merging of the irq_domain types is deferred to v3.7
In other news, this series adds helpers for creating static mappings on
a linear or tree mapping.

Merge tag 'vfio-for-v3.6' of git://github.com/awilliam/linux-vfio
Pull VFIO core from Alex Williamson:
"This series includes the VFIO userspace driver interface for the 3.6
kernel merge window. This driver is intended to provide a secure
interface for device access using IOMMU protection for applications
like assignment of physical devices to virtual machines.
Qemu will be the first user of this interface, enabling assignment of
PCI devices to Qemu guests. This interface is intended to eventually
replace the x86-specific assignment mechanism currently available in
KVM.
This interface has the advantage of being more secure, by working with
IOMMU groups to ensure device isolation and providing it's own
filtered resource access mechanism, and also more flexible, in not
being x86 or KVM specific (extensions to enable POWER are already
working).
This driver is originally the work of Tom Lyon, but has since been
handed over to me and gone through a complete overhaul thanks to the
input from David Gibson, Ben Herrenschmidt, Chris Wright, Joerg
Roedel, and others. This driver has been available in linux-next for
the last month."
Paul Mackerras says:
"I would be glad to see it go in since we want to use it with KVM on
PowerPC. If possible we'd like the PowerPC bits for it to go in as
well."
