Rework Tsi721 RapidIO DMA engine support to allow handling data
scatter/gather lists longer than number of hardware buffer descriptors in
the DMA channel's descriptor list.
The current implementation of Tsi721 DMA transfers requires that number of
entries in a scatter/gather list provided by a caller of
dmaengine_prep_rio_sg() should not exceed number of allocated hardware
buffer descriptors.
This patch removes the limitation by processing long scatter/gather lists
by sections that can be transferred using hardware descriptor ring of
configured size. It also introduces a module parameter
"dma_desc_per_channel" to allow run-time configuration of Tsi721 hardware
buffer descriptor rings.

This patchset implements creation of sysfs groups and attributes with
the purpose to show NILFS2 volume details, internal state of the driver
and to manage internal state of NILFS2 driver.
Sysfs is a virtual file system that exports information about devices
and drivers from the kernel device model to user space, and is also used
for configuration. NILFS2 is a complex file system that has segctor
thread, GC thread, checkpoint/snapshot model and so on. Sysfs namespace
provides native and easy way for: (1) getting info and statistics about
volume state; (2) getting info and configuration of internal subsystems
(segctor thread); (3) snapshots management.
Suggested patchset provides basis for managing segctor thread behaviour
and manipulation by snapshots. Currently, it informs only about segctor
thread's internal parameters and about mounted snapshots. But sysfs
interface can provide easy and simple way for deep management of segctor
thread and snapshots.
This patchset provides opportunity to manage interval of periodical
update of superblock (in seconds). Default value is 10 seconds. Now a
user can increase this value by means of
nilfs2/<device>/superblock/sb_update_frequency attribute in the case of
necessity.
Also the patchset provides opportunity to get information easily about
key volumes's parameters (free blocks, superblock write count,
superblock update frequency, latest segment info, dirty data blocks
count, count of clean segments, count of dirty segments and so on) in
real time manner. Such information can be used in scripts for subtle
management of filesystem.
Implemented functionality creates such groups:
(1) /sys/fs/nilfs2 - root group
(2) /sys/fs/nilfs2/features - group contains attributes that describe NILFS
file system driver features
(3) /sys/fs/nilfs2/<device> - group contains attributes that describe file
system partition's details
(4) /sys/fs/nilfs2/<device>/superblock - group contains attributes that describe
superblock's details
(5) /sys/fs/nilfs2/<device>/segctor - group contains attributes that describe
segctor thread activity details
(6) /sys/fs/nilfs2/<device>/segments - group contains attributes that describe
details about volume's segments
(7) /sys/fs/nilfs2/<device>/checkpoints - group contains attributes that describe
details about volume's checkpoints
(8) /sys/fs/nilfs2/<device>/mounted_snapshots - group contains group for every
mounted snapshot
(9) /sys/fs/nilfs2/<device>/mounted_snapshots/<snapshot> - group contains
details about mounted snapshot
This patch (of 9):
This patch adds code of creation /sys/fs/nilfs2 group and
/sys/fs/nilfs2/features group.
The features group contains attributes that describe NILFS
file system driver features:
(1) revision - show current revision of NILFS file system driver.
There are two formats of timestamp output - seconds and human-readable
format. Every showed timestamp has two sysfs files (time-<xxx> and
time-<xxx>-secs). One sysfs file (time-<xxx>) shows time in
human-readable format. Another sysfs file (time-<xxx>-secs) shows time in
seconds.
It was reported by Michael Semon that timestamp output in human-readable
format should be changed from "2014-4-12 14:5:38" to "2014-04-12
14:05:38". Second version of the patch fixes this issue.

The memcg uncharging code that is involved towards the end of a page's
lifetime - truncation, reclaim, swapout, migration - is impressively
complicated and fragile.
Because anonymous and file pages were always charged before they had their
page->mapping established, uncharges had to happen when the page type
could still be known from the context; as in unmap for anonymous, page
cache removal for file and shmem pages, and swap cache truncation for swap
pages. However, these operations happen well before the page is actually
freed, and so a lot of synchronization is necessary:
- Charging, uncharging, page migration, and charge migration all need
to take a per-page bit spinlock as they could race with uncharging.
- Swap cache truncation happens during both swap-in and swap-out, and
possibly repeatedly before the page is actually freed. This means
that the memcg swapout code is called from many contexts that make
no sense and it has to figure out the direction from page state to
make sure memory and memory+swap are always correctly charged.
- On page migration, the old page might be unmapped but then reused,
so memcg code has to prevent untimely uncharging in that case.
Because this code - which should be a simple charge transfer - is so
special-cased, it is not reusable for replace_page_cache().
But now that charged pages always have a page->mapping, introduce
mem_cgroup_uncharge(), which is called after the final put_page(), when we
know for sure that nobody is looking at the page anymore.
For page migration, introduce mem_cgroup_migrate(), which is called after
the migration is successful and the new page is fully rmapped. Because
the old page is no longer uncharged after migration, prevent double
charges by decoupling the page's memcg association (PCG_USED and
pc->mem_cgroup) from the page holding an actual charge. The new bits
PCG_MEM and PCG_MEMSW represent the respective charges and are transferred
to the new page during migration.
mem_cgroup_migrate() is suitable for replace_page_cache() as well,
which gets rid of mem_cgroup_replace_page_cache(). However, care
needs to be taken because both the source and the target page can
already be charged and on the LRU when fuse is splicing: grab the page
lock on the charge moving side to prevent changing pc->mem_cgroup of a
page under migration. Also, the lruvecs of both pages change as we
uncharge the old and charge the new during migration, and putback may
race with us, so grab the lru lock and isolate the pages iff on LRU to
prevent races and ensure the pages are on the right lruvec afterward.
Swap accounting is massively simplified: because the page is no longer
uncharged as early as swap cache deletion, a new mem_cgroup_swapout() can
transfer the page's memory+swap charge (PCG_MEMSW) to the swap entry
before the final put_page() in page reclaim.
Finally, page_cgroup changes are now protected by whatever protection the
page itself offers: anonymous pages are charged under the page table lock,
whereas page cache insertions, swapin, and migration hold the page lock.
Uncharging happens under full exclusion with no outstanding references.
Charging and uncharging also ensure that the page is off-LRU, which
serializes against charge migration. Remove the very costly page_cgroup
lock and set pc->flags non-atomically.

These patches rework memcg charge lifetime to integrate more naturally
with the lifetime of user pages. This drastically simplifies the code and
reduces charging and uncharging overhead. The most expensive part of
charging and uncharging is the page_cgroup bit spinlock, which is removed
entirely after this series.

This patch (of 4):
The memcg charge API charges pages before they are rmapped - i.e. have an
actual "type" - and so every callsite needs its own set of charge and
uncharge functions to know what type is being operated on. Worse,
uncharge has to happen from a context that is still type-specific, rather
than at the end of the page's lifetime with exclusive access, and so
requires a lot of synchronization.
Rewrite the charge API to provide a generic set of try_charge(),
commit_charge() and cancel_charge() transaction operations, much like
what's currently done for swap-in:
mem_cgroup_try_charge() attempts to reserve a charge, reclaiming
pages from the memcg if necessary.
mem_cgroup_commit_charge() commits the page to the charge once it
has a valid page->mapping and PageAnon() reliably tells the type.
mem_cgroup_cancel_charge() aborts the transaction.
This reduces the charge API and enables subsequent patches to
drastically simplify uncharging.
As pages need to be committed after rmap is established but before they
are added to the LRU, page_add_new_anon_rmap() must stop doing LRU
additions again. Revive lru_cache_add_active_or_unevictable().

A handful of driver-related changes. We've had a bunch of them going in through
other branches as well, so it's only a part of what we really have this release.
Larger pieces are:
* Removal of a now unused PWM driver for atmel
- This includes AVR32 changes that have been appropriately acked.
* Performance counter support for the arm CCN interconnect
* OMAP mailbox driver cleanups and consolidation
* PCI and SATA PHY drivers for SPEAr 13xx platforms
* Redefinition (with backwards compatibility!) of PCI DT bindings for Tegra to
better model regulators/power.

Unlike the board branch, this keeps having large sets of changes for
every release, but that's quite expected and is so far working well.
Most of this is plumbing for various device bindings and new platforms,
but there's also a bit of cleanup and code removal for things that
are moved from platform code to DT contents (some OMAP clock code in
particular).
There's also a pinctrl driver for tegra here (appropriately acked),
that's introduced this way to make it more bisectable.
I'm happy to say that there were no conflicts at all with this branch
this release, which means that changes are flowing through our tree as
expected instead of merged through driver maintainers (or at least not
done with conflicts).
There are several new boards added, and a couple of SoCs. In no particular
order:
* Rockchip RK3288 SoC support, including DTS for a dev board that they
have seeded with some community developers.
* Better support for Hardkernel Exynos4-based ODROID boards.
* CCF conversions (and dtsi contents) for several Renesas platforms.
* Gumstix Pepper (TI AM335x) board support
* TI eval board support for AM437x
* Allwinner A23 SoC, very similar to existing ones which mostly has
resulted in DT changes for support. Also includes support for an Ippo
tablet with the chipset.
* Allwinner A31 Hummingbird board support, not to be confused with the
SolidRun i.MX-based Hummingboard.
* Tegra30 Apalis board support

Merge tag 'dt-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC device-tree changes from Olof Johansson:
"Unlike the board branch, this keeps having large sets of changes for
every release, but that's quite expected and is so far working well.
Most of this is plumbing for various device bindings and new
platforms, but there's also a bit of cleanup and code removal for
things that are moved from platform code to DT contents (some OMAP
clock code in particular).
There's also a pinctrl driver for tegra here (appropriately acked),
that's introduced this way to make it more bisectable.
I'm happy to say that there were no conflicts at all with this branch
this release, which means that changes are flowing through our tree as
expected instead of merged through driver maintainers (or at least not
done with conflicts).
There are several new boards added, and a couple of SoCs. In no
particular order:
- Rockchip RK3288 SoC support, including DTS for a dev board that
they have seeded with some community developers.
- Better support for Hardkernel Exynos4-based ODROID boards.
- CCF conversions (and dtsi contents) for several Renesas platforms.
- Gumstix Pepper (TI AM335x) board support
- TI eval board support for AM437x
- Allwinner A23 SoC, very similar to existing ones which mostly has
resulted in DT changes for support. Also includes support for an
Ippo tablet with the chipset.
- Allwinner A31 Hummingbird board support, not to be confused with
the SolidRun i.MX-based Hummingboard.
- Tegra30 Apalis board support"

This merge window brings a good size of cleanups on various
platforms. Among the bigger ones:
* Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have
lacked active support for quite a while, and after asking around nobody
showed interest in keeping them around. If needed, they could be
resurrected in the future but it's more likely that we would prefer
reintroduction of them as DT and multiplatform-enabled platforms
instead.
* OMAP4 controller code register define diet. They defined a lot of registers
that were never actually used, etc.
* Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate)
to drivers/soc so it can be shared with 64-bit code. This also converts them
over to traditional driver models where possible.
* Removal of legacy gpio-samsung driver, since the last users have been
removed (moved to pinctrl)
Plus a bunch of smaller changes for various platforms that sort of
dissapear in the diffstat for the above. clps711x cleanups, shmobile
header file refactoring/moves for multiplatform friendliness, some misc
cleanups, etc.

Document new compatible for PWM founding on RK3288 SoC
Signed-off-by: Caesar Wang <caesar.wang@rock-chips.com>
Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
Now the devices show up under hid no matter the connection (for USB
and Bluetooth, not serial nor i2c).
The USB devices can now be easily found under
/sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>
The Bluetooth devices could also be found under this path since their
inclusion (April 2010), so this patch fixes the non-precise "hidraw*" path
for them.
The ABI has been unified while setting the LEDs and OLEDs. So Bluetooth
devices lost their own LED selector but use the USB sysfs attribute.
For OLEDs, Bluetooth devices handle only 1-bit images instead of 4 for USB.
The documentation has been updated to match this.

"Like all good pull reqs this ends with a revert, so it must mean we
tested it,

This pull is missing nouveau, Ben has been stuck trying to track down
a very longstanding bug that revealed itself due to some other
changes. I've asked him to send you a direct pull request for nouveau
once he cleans things up. I'm away until Monday so don't want to
delay things, you can make a decision on that when he sends it, I have
my phone so I can ack things just not really merge much.
It has one trivial conflict with your tree in armada_drv.c, and also
the pull request contains some component changes that are already in
your tree, the base tree from Russell went via Greg's tree already,
but some stuff still shows up in here that doesn't when I merge my
tree into yours.
Otherwise all pretty standard graphics fare, one new driver and
changes all over the place.
New drivers:
- sti kms driver for STMicroelectronics chipsets stih416 and stih407.

never "disable" a mux setting.

this will be done in parallel in the GPIO subsystem and

In REF-walk mode, ->d_manage can return -EISDIR to indicate
that the dentry is not really a mount trap (or even a mount point)
and that any mounts or any DCACHE_NEED_AUTOMOUNT flag should be
ignored.
RCU-walk mode doesn't currently support this, so if there is a dentry
with DCACHE_NEED_AUTOMOUNT set but which shouldn't be a mount-trap,
lookup_fast() will always drop in REF-walk mode.
With this patch, an -EISDIR from ->d_manage will always cause mounts
and automounts to be ignored, both in REF-walk and RCU-walk.

they had small conflicts (respectively within KVM documentation,
and with 3.16-rc changes). Since they were all within the subsystem,
I took care of them.
Stephen Rothwell reported some snags in PPC builds, but they are all
fixed now; the latest linux-next report was clean.
New features for ARM include:
- KVM VGIC v2 emulation on GICv3 hardware
- Big-Endian support for arm/arm64 (guest and host)
- Debug Architecture support for arm64 (arm32 is on Christoffer's todo list)
And for PPC:
- Book3S: Good number of LE host fixes, enable HV on LE
- Book3S HV: Add in-guest debug support
This release drops support for KVM on the PPC440. As a result, the
PPC merge removes more lines than it adds. :)
I also included an x86 change, since Davidlohr tied it to an independent
bug report and the reporter quickly provided a Tested-by; there was no
reason to wait for -rc2.

Pull powerpc updates from Ben Herrenschmidt:
"This is the powerpc new goodies for 3.17. The short story:
The biggest bit is Michael removing all of pre-POWER4 processor
support from the 64-bit kernel. POWER3 and rs64. This gets rid of a
ton of old cruft that has been bitrotting in a long while. It was
broken for quite a few versions already and nobody noticed. Nobody
uses those machines anymore. While at it, he cleaned up a bunch of
old dusty cabinets, getting rid of a skeletton or two.
Then, we have some base VFIO support for KVM, which allows assigning
of PCI devices to KVM guests, support for large 64-bit BARs on
"powernv" platforms, support for HMI (Hardware Management Interrupts)
on those same platforms, some sparse-vmemmap improvements (for memory
hotplug),
There is the usual batch of Freescale embedded updates (summary in the
merge commit) and fixes here or there, I think that's it for the
highlights"

Pull ACPI and power management updates from Rafael Wysocki:
"Again, ACPICA leads the pack (47 commits), followed by cpufreq (18
commits) and system suspend/hibernation (9 commits).
From the new code perspective, the ACPICA update brings ACPI 5.1 to
the table, including a new device configuration object called _DSD
(Device Specific Data) that will hopefully help us to operate device
properties like Device Trees do (at least to some extent) and changes
related to supporting ACPI on ARM.
Apart from that we have hibernation changes making it use radix trees
to store memory bitmaps which should speed up some operations carried
out by it quite significantly. We also have some power management
changes related to suspend-to-idle (the "freeze" sleep state) support
and more preliminary changes needed to support ACPI on ARM (outside of
ACPICA).
The rest is fixes and cleanups pretty much everywhere.
Specifics:
- ACPICA update to upstream version 20140724. That includes ACPI 5.1
material (support for the _CCA and _DSD predefined names, changes
related to the DMAR and PCCT tables and ARM support among other
things) and cleanups related to using ACPICA's header files. A

for no good reason in this function and makes using it unnecessary

generate a compile error instead of using the wrong parameter order.

The default size of the ring buffer is too small for machines with a
large amount of CPUs under heavy load. What ends up happening when
debugging is the ring buffer overlaps and chews up old messages making
debugging impossible unless the size is passed as a kernel parameter.
An idle system upon boot up will on average spew out only about one or
two extra lines but where this really matters is on heavy load and that
will vary widely depending on the system and environment.
There are mechanisms to help increase the kernel ring buffer for tracing
through debugfs, and those interfaces even allow growing the kernel ring
buffer per CPU. We also have a static value which can be passed upon
boot. Relying on debugfs however is not ideal for production, and
relying on the value passed upon bootup is can only used *after* an
issue has creeped up. Instead of being reactive this adds a proactive
measure which lets you scale the amount of contributions you'd expect to
the kernel ring buffer under load by each CPU in the worst case
scenario.
We use num_possible_cpus() to avoid complexities which could be
introduced by dynamically changing the ring buffer size at run time,
num_possible_cpus() lets us use the upper limit on possible number of
CPUs therefore avoiding having to deal with hotplugging CPUs on and off.
This introduces the kernel configuration option LOG_CPU_MAX_BUF_SHIFT
which is used to specify the maximum amount of contributions to the
kernel ring buffer in the worst case before the kernel ring buffer flips
over, the size is specified as a power of 2. The total amount of
contributions made by each CPU must be greater than half of the default
kernel ring buffer size (1 << LOG_BUF_SHIFT bytes) in order to trigger
an increase upon bootup. The kernel ring buffer is increased to the
next power of two that would fit the required minimum kernel ring buffer
size plus the additional CPU contribution. For example if LOG_BUF_SHIFT
is 18 (256 KB) you'd require at least 128 KB contributions by other CPUs
in order to trigger an increase of the kernel ring buffer. With a
LOG_CPU_BUF_SHIFT of 12 (4 KB) you'd require at least anything over > 64
possible CPUs to trigger an increase. If you had 128 possible CPUs the
amount of minimum required kernel ring buffer bumps to:
((1 << 18) + ((128 - 1) * (1 << 12))) / 1024 = 764 KB
Since we require the ring buffer to be a power of two the new required
size would be 1024 KB.
This CPU contributions are ignored when the "log_buf_len" kernel
parameter is used as it forces the exact size of the ring buffer to an
expected power of two value.

Pull timer and time updates from Thomas Gleixner:
"A rather large update of timers, timekeeping & co
- Core timekeeping code is year-2038 safe now for 32bit machines.
Now we just need to fix all in kernel users and the gazillion of
user space interfaces which rely on timespec/timeval :)
- Better cache layout for the timekeeping internal data structures.
- Proper nanosecond based interfaces for in kernel users.
- Tree wide cleanup of code which wants nanoseconds but does hoops
and loops to convert back and forth from timespecs. Some of it
definitely belongs into the ugly code museum.
- Consolidation of the timekeeping interface zoo.
- A fast NMI safe accessor to clock monotonic for tracing. This is a
long standing request to support correlated user/kernel space
traces. With proper NTP frequency correction it's also suitable
for correlation of traces accross separate machines.
- Checkpoint/restart support for timerfd.
- A few NOHZ[_FULL] improvements in the [hr]timer code.
- Code move from kernel to kernel/time of all time* related code.
- New clocksource/event drivers from the ARM universe. I'm really
impressed that despite an architected timer in the newer chips SoC
manufacturers insist on inventing new and differently broken SoC
specific timers.
[ Ed. "Impressed"? I don't think that word means what you think it means ]
- Another round of code move from arch to drivers. Looks like most
of the legacy mess in ARM regarding timers is sorted out except for
a few obnoxious strongholds.
- The usual updates and fixlets all over the place"

A couple of nice new features this month, the ability to map regulators
in order to allow voltage control by external coprocessors is something
people have been asking for for a long time.
- Improved support for switch only "regulators", allowing current state
to be read from the parent regulator but no setting.
- Support for obtaining the register access method used to set
voltages, for use in systems which can offload control of this to a
coprocessor (typically for DVFS).
- Support for Active-Semi AC8846, Dialog DA9211 and Texas Instruments
TPS65917.

- p2p support for the ST21NFCA driver
- A few fixes an enhancements for the NFC digital laye"
For the Atheros bits, Kalle says:
"Michal and Janusz did some important RX aggregation fixes, basically we
were missing RX reordering altogether. The 10.1 firmware doesn't support
Ad-Hoc mode and Michal fixed ath10k so that it doesn't advertise Ad-Hoc
support with that firmware. Also he implemented a workaround for a KVM
issue."
For the Bluetooth bits, Gustavo and Johan say:
"To quote Gustavo from his previous request:
'Some last minute fixes for -next. We have a fix for a use after free in
RFCOMM, another fix to an issue with ADV_DIRECT_IND and one for ADV_IND with
auto-connection handling. Last, we added support for reading the codec and
MWS setting for controllers that support these features.'
Additionally there are fixes to LE scanning, an update to conform to the 4.1
core specification as well as fixes for tracking the page scan state. All
of these fixes are important for 3.17."
And,
"We've got:
- 6lowpan fixes/cleanups
- A couple crash fixes, one for the Marvell HCI driver and another in LE SMP.
- Fix for an incorrect connected state check
- Fix for the bondable requirement during pairing (an issue which had
crept in because of using "pairable" when in fact the actual meaning
was "bondable" (these have different meanings in Bluetooth)"
Along with those are some late-breaking hardware support patches in
brcmfmac and b43 as well as a stray ath9k patch.

This series of patches add the support of DRM/KMS drivers for STMicroelectronics
chipsets stih416 and stih407.
Hardware is split in two main blocks: Compositor and TVout. Each of them
includes specific hardware IPs and the display timing are controlled by a specific
Video Timing Generator hardware IP (VTG).
Compositor is made of the follow hardware IPs:
- GDP (Generic Display Pipeline) which is an entry point for graphic (RGB)
buffers
- VDP (Video Diplay Pipeline) which is an entry point for video (YUV) buffers
- HQVDP (High Quality Video Display Processor) that supports scaling,
deinterlacing and some miscellaneous image quality improvements.
It fetches the Video decoded buffers from memory, processes them and pushes
them to the Compositor through a HW dedicated bus.
- Mixer is responsible of mixing all the entries depending of their
respective z-order and layout
TVout is divided in 3 parts:
- HDMI to generate HDMI signals, depending of chipset version HDMI phy can
change.
- HDA to generate signals for HD analog TV
- VIP to control/switch data path coming from Compositor
On stih416 compositor and Tvout are on different dies so a Video Trafic Advance
inter-die Communication mechanism (VTAC) is needed.

In addition of the drivers for the IPs listed before a thin I2C driver (hdmiddc) is used
by HDMI driver to retrieve EDID for monitor.
To unify interfaces of GDP and VDP we create a "layer" interface called by
compositor to control both GPD and VDP.
Hardware have memory contraints (alignment, contiguous) so we use CMA drm helpers functions
to allocate frame buffer.
File naming convention is:
- sti_* for IPs drivers
- sti_drm_* for drm functions implementation.

to the ftrace function callback infrastructure. It's introducing a
way to allow different functions to call directly different trampolines
instead of all calling the same "mcount" one.
The only user of this for now is the function graph tracer, which always
had a different trampoline, but the function tracer trampoline was called
and did basically nothing, and then the function graph tracer trampoline
was called. The difference now, is that the function graph tracer
trampoline can be called directly if a function is only being traced by
the function graph trampoline. If function tracing is also happening on
the same function, the old way is still done.
The accounting for this takes up more memory when function graph tracing
is activated, as it needs to keep track of which functions it uses.
I have a new way that wont take as much memory, but it's not ready yet
for this merge window, and will have to wait for the next one.
Another big change was the removal of the ftrace_start/stop() calls that
were used by the suspend/resume code that stopped function tracing when
entering into suspend and resume paths. The stop of ftrace was done
because there was some function that would crash the system if one called
smp_processor_id()! The stop/start was a big hammer to solve the issue
at the time, which was when ftrace was first introduced into Linux.
Now ftrace has better infrastructure to debug such issues, and I found
the problem function and labeled it with "notrace" and function tracing
can now safely be activated all the way down into the guts of suspend
and resume.
Other changes include clean ups of uprobe code.
Clean up of the trace_seq() code.
And other various small fixes and clean ups to ftrace and tracing.

some non-critical fixes and improvements to the framework core.
Changes to the clock framework core include:
* improvements to printks on errors
* flattening the previously hierarchal structure of per-clock entries
in debugfs
* allow per-clock debugfs entries that are specific to a particular
clock driver
* configure initial clock parent and/or initial clock rate from Device
Tree
* several feature enhancements to the composite clock type
* misc fixes
New clock drivers added include:
* TI Palmas PMIC
* Allwinner A23 SoC
* Qualcomm APQ8084 and IPQ8064 SoCs
* Rockchip rk3188, rk3066 and rk3288 SoCs
* STMicroelectronics STiH407 SoC
* Cirrus Logic CLPS711X SoC
Many fixes, feature enhancements and further clock tree support for
existing clock drivers also were merged, such as Samsung's "ARMCLK down"
power saving feature for their Exynos4 & Exynos5 SoCs.

Pull cgroup changes from Tejun Heo:
"Mostly changes to get the v2 interface ready. The core features are
mostly ready now and I think it's reasonable to expect to drop the
devel mask in one or two devel cycles at least for a subset of
controllers.
- cgroup added a controller dependency mechanism so that block cgroup
can depend on memory cgroup. This will be used to finally support
IO provisioning on the writeback traffic, which is currently being
implemented.
- The v2 interface now uses a separate table so that the interface
files for the new interface are explicitly declared in one place.
Each controller will explicitly review and add the files for the
new interface.
- cpuset is getting ready for the hierarchical behavior which is in
the similar style with other controllers so that an ancestor's
configuration change doesn't change the descendants' configurations
irreversibly and processes aren't silently migrated when a CPU or
node goes down.
All the changes are to the new interface and no behavior changed for
the multiple hierarchies"

This has been a pretty exciting release in terms of the framework, we've
finally got support for multiple CODECs attached to a single DAI link
which has been something there's been interest in as long as I've been
working on ASoC. A big thanks to Benoit and Misael for their work on
this.
Otherwise it's been a fairly standard release for development, including
more componentisation work from Lars-Peter and a good selection of both
CODEC and CPU drivers.
- Support for multiple CODECs attached to a single DAI, enabling
systems with for example multiple DAC/speaker drivers on a single
link, contributed by Benoit Cousson based on work from Misael Lopez
Cruz.
- Support for byte controls larger than 256 bytes based on the use of
TLVs contributed by Omair Mohammed Abdullah.
- More componentisation work from Lars-Peter Clausen.
- The remainder of the conversions of CODEC drivers to params_width()
- Drivers for Cirrus Logic CS4265, Freescale i.MX ASRC blocks, Realtek
RT286 and RT5670, Rockchip RK3xxx I2S controllers and Texas Instruments
TAS2552.
- Lots of updates and fixes, especially to the DaVinci, Intel,
Freescale, Realtek, and rcar drivers.

Now that we (almost) have enough dependencies in place (MMCC, RPM, etc),
add necessary DT support so that we can use drm/msm on upstream kernel.
