git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull main powerpc updates from Ben Herrenschmidt:
"This time around, the powerpc merges are going to be a little bit more
complicated than usual.
This is the main pull request with most of the work for this merge
window. I will describe it a bit more further down.
There is some additional cpuidle driver work, however I haven't
included it in this tree as it depends on some work in tip/timer-core
which Thomas accidentally forgot to put in a topic branch. Since I
didn't want to carry all of that tip timer stuff in powerpc -next, I
setup a separate branch on top of Thomas tree with just that cpuidle
driver in it, and Stephen has been carrying that in next separately
for a while now. I'll send a separate pull request for it.
Additionally, two new pieces in this tree add users for a sysfs API
that Tejun and Greg have been deprecating in drivers-core-next.
Thankfully Greg reverted the patch that removes the old API so this
merge can happen cleanly, but once merged, I will send a patch
adjusting our new code to the new API so that Greg can send you the
removal patch.
Now as for the content of this branch, we have a lot of perf work for
power8 new counters including support for our new "nest" counters
(also called 24x7) under pHyp (not natively yet).
We have new functionality when running under the OPAL firmware
(non-virtualized or KVM host), such as access to the firmware error
logs and service processor dumps, system parameters and sensors, along
with a hwmon driver for the latter.
There's also a bunch of bug fixes accross the board, some LE fixes,
and a nice set of selftests for validating our various types of copy
loops.
On the Freescale side, we see mostly new chip/board revisions, some
clock updates, better support for machine checks and debug exceptions,
etc..."

usb: patches for v3.15
another substantial pull request with new features all over
the place.
dwc3 got a bit closer towards hibernation support with after
a few patches re-factoring code to be reused for hibernation.
Also in dwc3 two new workarounds for known silicon bugs have
been implemented, some randconfig build errors have been fixed,
and it was taught about the new generic phy layer.
MUSB on AM335x now supports isochronous transfers thanks to
George Cherian's work.
The atmel_usba driver got two crash fixes: one when no endpoint
was specified in DeviceTree data and another when stopping the UDC
in DEBUG builds.
Function FS got a much needed fix to ffs_epfile_io() which was
copying too much data to userspace in some cases.
The printer gadget got a fix for a possible deadlock and plugged
a memory leak.
Ethernet drivers now use NAPI for RX which gives improved throughput.
Other than that, the usual miscelaneous fixes, cleanups, and
the like.

Adapted dwc3 core to use the Generic PHY Framework. So for init, exit,
power_on and power_off the following APIs are used phy_init(), phy_exit(),

This brings the xhci-platform bindings in sync with what we've done for
the ohci- and ehci-platform drivers. As discussed there using platform as a
postfix is a bit weird as the platform bus is a Linux specific thing and
the bindings are supposed to be OS agnostic.
Note that the old xhci-platform compatible string is kept around for, well,

The initial versions of the devicetree enablement patches for ehci-platform
used "ehci-platform" as compatible string. However this was disliked by various
reviewers because the platform bus is a Linux invention and devicetree is
supposed to be OS agnostic. After much discussion I gave up, added a:
"depends on !PPC_OF" to Kconfig to avoid a known conflict with PPC-OF platforms
and went with the generic usb-ehci as requested.
In retro-spect I should have chosen something different, the dts files for many
existing boards already claim to be compatible with "usb-ehci", ie they have:
compatible = "ti,ehci-omap", "usb-ehci";
In theory this should not be a problem since the "ti,ehci-omap" entry takes
presedence, but in practice using a conflicting compatible string is an issue,
because it makes which driver gets used depend on driver registration order.
This patch changes the compatible string claimed by ehci-platform to
"generic-ehci", avoiding the driver registration / module loading ordering
problems, and removes the "depends on !PPC_OF" workaround.

Currently ehci-platform is only used in combination with devicetree when used
with some Via socs. By extending it to (optionally) get clks and a phy from
devicetree, and enabling / disabling those on power_on / off, it can be used
more generically. Specifically after this commit it can be used for the
ehci controller on Allwinner sunxi SoCs.
Since ehci-platform is intended to handle any generic enough non pci ehci
device, add a "usb-ehci" compatibility string.
There already is a usb-ehci device-tree bindings document, update this
with clks and phy bindings info.
Although actually quite generic so far the via,vt8500 compatibilty string
had its own bindings document. Somehow we even ended up with 2 of them. Since
these provide no extra information over the generic usb-ehci documentation,
this patch removes them.
The ehci-ppc-of.c driver also claims the usb-ehci compatibility string,
even though it mostly is ibm,usb-ehci-440epx specific. ehci-platform.c is
not needed on ppc platforms, so add a !PPC_OF dependency to it to avoid
2 drivers claiming the same compatibility string getting build on ppc.

We can now enable VERBOSE_DEBUG on builds of drivers/usb/gadget/

The "mentor,musb" binding isn't documented so I was about
to document it.
The node is missing a few properties for configuration like
"multipoint", "dyn_fifo", "num_eps" or "ram_bits". However
I am not sure "missing" is the right word here because some
of those informations might be obtained from the chip itself
but it is not done (yet).
Further the ePARP 2.3.1 says the matching goes from left to
right taking the fist match. Right now there is jus a driver
for "stericsson,db8500-musb" and none for "mentor,musb".
I'm not 100% that it is simply possible to have a generic
since even for DMA we have ifdefs in the driver between
"generic mentor dma" and "ux500 dma" and I mean within musb
and not the dma code.
For that reason (that I am not sure a generic musb binding
is possible and how its binding / required properties will
look like) and the reason that we have here a minor binding
without a driver to look at I suggest to remove that binding.
If the majority of people prefer to keep this binding I'm
curious how the documentation of the binding should look like.

The support for both am335x-USB instances required changes to the device
tree bindings. This patch reflects these changes in the bindings
document.
v3…v4:
- remove the child node for USB. This is driver specific on won't be
reflected in the device tree
- use the "mentor" prefix instead of "mg".
- use "dr_mode" istead of "mg,port-mode" for the port mode. The former
is used by a few other drivers.
v2…v3:
- use proper usb-phy nodes in evm, bone and evmsk device tree.
v1…v2:
- use mg prefix for the Metor Graphics specific attributes
- use power in mA not in mA/2 as specifed in the USB2.0 specification
- use usbX-phy instead of usbX_phy
- use dma-controller instead of dma

Sarah writes:
xhci: Platform updates, 64-bit DMA, and trace events for 3.12.
Hi Greg,
This pull request includes one new feature for the xhci-plat driver (device
tree support). Felipe was fine with the patch last I checked, but hadn't
provided an official Acked-by line.
This pull request also includes 13 patches from my FOSS Outreach Program for
Women (OPW) intern, Xenia. She fixed a bug in the xHCI driver so that the
driver can allocate 64-bit consistent DMA, converted the driver to use dynamic
debugging, and added a bunch of new trace events for the xHCI driver. The
python plugin for trace-cmd should be up on git hub shortly, although the trace
events are usable without it.
I'm very happy with the progress that Xenia has made, and I look forward to her
future contributions to the Linux kernel.

Felipe writes:
usb: patches for v3.12 merge window
All patches here have been pending on linux-usb
and sitting in linux-next for a while now.
The biggest things in this tag are:
DWC3 learned proper usage of threaded IRQ
handlers and now we spend very little time
in hardirq context.
MUSB now has proper support for BeagleBone and
Beaglebone Black.
Tegra's USB support also got quite a bit of love
and is learning to use PHY layer and generic DT
attributes.
Other than that, the usual pack of cleanups and
non-critical fixes follow.

Refactor so that register writes for configuration are only performed if
the device has a regmap provided and also register as a platform driver.
This allows the driver to be used to manage GPIO based control of the
device.

The binding document says that all properties are required but in fact
almost all are optional (and should be) - update the document to reflect
this.
