The 25 MHz reference clock has better stability so its use is prefered over the
core clock. Change the Armada 375 clock initialization to use this reference
clock. To ensure the driver is compatible with an old devicetree, also provide
a fallback path which will silently return to the previous behavior.
While here, add the clock specification to the binding documentation.

The memory controller on NVIDIA Tegra exposes various knobs that can be
used to tune the behaviour of the clients attached to it.
In addition, the memory controller implements an SMMU (IOMMU) which can
translate I/O virtual addresses to physical addresses for clients. This
is useful for scatter-gather operation on devices that don't support it
natively and for virtualization or process separation.

The imx-drm driver was put into staging mostly for the following reasons,
all of which have been addressed or superseded:
- convert the irq driver to use linear irq domains
- work out the device tree bindings, this lead to the common of_graph
bindings being used
- factor out common helper functions, this mostly resulted in the
component framework and drm of_graph helpers.
Before adding new fixes, and certainly before adding new features,
move it into its proper place below drivers/gpu/drm.

usb: patches for v3.19 merge window
This time, a very pull request with 216 non-merge
commits. Most of the commits contained here are
sparse or coccinelle fixes ranging from missing
'static' to returning 0 in case of errors.
More importantly, we have the removal the now
unnecessary 'driver' argument to ->udc_stop().
DWC2 learned about Dual-Role builds. Users of
this IP can now have a single driver built for
host and device roles.
DWC3 got support for two new HW platforms: Exynos7
and AMD.
The Broadcom USB 3.0 Device Controller IP is now
supported and so is PLX USB338x, which means DWC3
has lost is badge as the only USB 3.0 peripheral
IP supported on Linux.
Thanks for Tony Lindgren's work, we can now have
a distro-like kernel where all MUSB glue layers
can be built into the same kernel (statically
or dynamically linked) and it'll work in PIO (DMA
will come probably on v3.20).
Other than these, the usual set of cleanups and
non-critical fixes.

Overlays are a method to dynamically modify part of the kernel's
device tree with dynamically loaded data. Add the core functionality to
parse, apply and remove an overlay changeset. The core functionality
takes care of managing the overlay data format and performing the add
and remove. Drivers are expected to use the overlay functionality to
support custom expansion busses commonly found on consumer development
boards like the BeagleBone or Raspberry Pi.
The overlay code uses CONFIG_OF_DYNAMIC changesets to perform the low
level work of modifying the devicetree.
Documentation about internal and APIs is provided in
Documentation/devicetree/overlay-notes.txt
v2:
- Switch from __of_node_alloc() to __of_node_dup()
- Documentation fixups
- Remove 2-pass processing of properties
- Remove separate ov_lock; just use the DT mutex.
v1:
- Drop delete capability using '-' prefix. The '-' prefixed names
are valid properties and nodes and there is no need for it just yet.
- Do not update special properties - name & phandle ones.
- Change order of node attachment, so that the special property update
works.

Some clock modules on the A31 use PLL6x2 as one of their inputs.
This patch changes the PLL6 implementation for A31 to a divs clock,
i.e. clock with multiple outputs that have different dividers.
The first output will be the normal PLL6 output, and the second
will be PLL6x2.
This patch fixes the PLL6 N factor in the clock driver, and removes
any /2 dividers in the PLL6 factors clock part. The N factor counts
from 1 to 32, mapping to values 0 to 31, as shown in the A31 manual.

The clock controller module (CCM) has several clock inputs, which
are connected to external crystal oscillators. To reflect this,
assign these fixed clocks to the CCM node directly.
This especially resolves initialization order dependencies we had
with the earlier initialization code: When resolving of the fixed

rate of 0.

"It has been a while since my last pull request, so we accumulated

* TDLS off-channel support set from Arik/Liad, with some support
patches I did
* custom regulatory fixes from Arik

* add back radiotap vendor namespace support (myself)
* random MAC address scanning for cfg80211/mac80211/hwsim (myself)
* CSA improvements (Luca)
* WoWLAN Net Detect (wake on network found) support (Luca)
* and lots of other smaller changes from many people"
For the Bluetooth bits, Johan says:
"Here's another set of patches for 3.19. Most of it is again fixes and
cleanups to ieee802154 related code from Alexander Aring. We've also got
better handling of hardware error events along with a proper API for HCI
drivers to notify the HCI core of such situations. There's also a minor
fix for mgmt events as well as a sparse warning fix. The code for
sending HCI commands synchronously also gets a fix where we might loose
the completion event in the case of very fast HW (particularly easily
reproducible with an emulated HCI device)."
And...
"Here's another bluetooth-next pull request for 3.19. We've got:
- Various fixes, cleanups and improvements to ieee802154/mac802154
- Support for a Broadcom BCM20702A1 variant
- Lots of lockdep fixes
- Fixed handling of LE CoC errors that should trigger SMP"
For the Atheros bits, Kalle says:
"One ath6kl patch and rest for ath10k, but nothing really major which
stands out. Most notable:
o fix resume (Bartosz)
o firmware restart is now faster and more reliable (Michal)
o it's now possible to test hardware restart functionality without
crashing the firmware using hw-restart parameter with

On top of that...both ath9k and mwifiex get their usual level of

I also pulled from the wireless tree in order to avoid some merge issues.

Add "micrel,rmii-reference-clock-select-25-mhz" to Micrel ethernet PHY
binding documentation.
This property is needed to properly describe some revisions of Micrel
PHYs which has the function of this configuration bit inverted so that
setting it enables 25 MHz rather than 50 MHz clock mode.
Note that a clock reference ("rmii-ref") is still needed to actually
select either mode.
