Pull pin control updates from Linus Walleij:
"Main pin control pull request for the v3.13 cycle.
The changes hitting arch/blackfin are ACKed by the Blackfin
maintainer, and the device tree bindings are ACKed to the extent
possible by someone from the device tree maintainers group.
- Blackfin ADI pin control driver, we move yet another architecture
under this subsystem umbrella.
- Incremental updates to the Renesas Super-H PFC pin control driver.
New subdriver for the r8a7791 SoC.
- Non-linear GPIO ranges from the gpiolib side of things, this
enabled simplified device tree bindings by referring entire groups
of pins on some pin controller to act as back-end for a certain
GPIO-chip driver.
- Add the Abilis TB10x pin control driver used on the ARC
architecture. Also the corresponding GPIO driver is merged through
this tree, so the ARC has full support for pins and GPIOs after
this.
- Subdrivers for Freescale i.MX1, i.MX27 and i.MX50 pin controller
instances. The i.MX1 and i.MX27 is an entirely new family
(silicon) of controllers whereas i.MX50 is a variant of the
previous supported controller.
- Then the usual slew of fixes, cleanups and incremental updates"
The ARC DT changes are apparently still pending, that hopefully gets
sorted out in a timely manner.

Pull sound updates from Takashi Iwai:
"There are no too intrusive changes in this update batch. The biggest
LOC is found in the new DICE driver, and other small changes are
scattered over the whole sound subtree (which is a common pattern).
Below are highlights:
- ALSA core:
* Memory allocation support with genpool
* Fix blocking in drain ioctl of compress_offload
- HD-audio:
* Improved AMD HDMI supports
* Intel HDMI detection improvements
* thinkpad_acpi mute-key integration
* New PCI ID, New ALC255,285,293 codecs, CX20952
- USB-audio:
* New buffer size management
* Clean up endpoint handling codes
- ASoC:
* Further work on the dmaengine helpers, including support for
configuring the parameters for DMA by reading the capabilities of
the DMA controller which removes some guesswork and magic numbers
from drivers.
* A refresh of the documentation.
* Conversions of many drivers to direct regmap API usage in order
to allow the ASoC level register I/O code to be removed, this
will hopefully be completed by v3.14.
* Support for using async register I/O in DAPM, reducing the time
taken to implement power transitions on systems that support it.

to roll out some noticable performance improvements which drivers

Pull regulator updates from Mark Brown:
"Lots of driver updates here plus some nice new core features, the main
one being the first:
- Enable support for providing a dummy regulator when we know that
one must exist for the device to be functional. This makes it much
easier to add regulator support to drivers since we don't require
that the machine integration for all systems using the device be
updated to provide regulators.
- Substantial reduction in the amount of busy waiting done while
waiting for enables to complete.
- Allow MFDs to distribute regulator supplies to child devices so we
don't have to expose the internal structure of MFDs outside of the
driver.
- Managed registeration for regulators"

Pull regmap updates from Mark Brown:
"The main thing this time around has been some improvments to async
I/O.
- Cleaned up the async I/O support and extended it to allow single
register writes more easily. This is now used where possible for
internally generated I/O, providing performance improvements for
devices that can do async I/O.
- An API for issuing a sequence of register writes as a single
operation. Some devices and buses can take advantage of this to do
the I/O faster.
- Addition of regmap_field APIs which help drivers for devices with
repeated IPs or which move registers around between revisions to
share helpers.
- Support for SPMI buses"

I'm still sitting on a handful of patches to enable the new ABI that I

incertainty (they are pretty fresh) I want to keep them separate.
Other notable changes are some infrastructure bits to better handle
PCI pass-through under KVM, some bits and pieces added to the new
PowerNV platform support such as access to the CPU SCOM bus via sysfs,
and support for EEH error handling on PHB3 (Power8 PCIe).
