The maintainers for mach-msm no longer have any plans to support
or test the platforms supported by this architecture[1]. Most likely
there aren't any active users of this code anyway, so let's
delete it.

Fixed behaviour of get_mctrl() serial driver function as documented in:
https://www.kernel.org/doc/Documentation/serial/driver
Added device-tree properties 'dcd-override', 'dsr-override',
'cts-override', and 'ri-override' specific to the Synopsis 8250
DesignWare UART driver. Allows one to force Data Carrier Detect,
Clear To Send, and Data Set Ready signals to permanently be reported as
active. The Ring indicator can be forced to be reported as inactive.
It is possible that if modem control signalling is enabled on a port
that doesn't have these pins (e.g. - a simple two wire Tx/Rx port), the
driver can hang indefinitely waiting for the state to change. The new
DT properties allow the driver to ignore the state of these pins on
serial ports that don't support them, as recommended in the kernel
documentation.

Pull power management and ACPI fixes from Rafael Wysocki:
"These are fixes for recent regressions (ACPI resources management,
suspend-to-idle), stable-candidate fixes (ACPI backlight), fixes
related to the wakeup IRQ management changes made in v3.18, other
fixes (suspend-to-idle, cpufreq ppc driver) and a couple of cleanups
(suspend-to-idle, generic power domains, ACPI backlight).
Specifics:
- Fix ACPI resources management problems introduced by the recent
rework of the code in question (Jiang Liu) and a build issue
introduced by those changes (Joachim Nilsson).
- Fix a recent suspend-to-idle regression on systems where entering
idle states causes local timers to stop, prevent suspend-to-idle
from crashing in restricted configurations (no cpuidle driver,
cpuidle disabled etc.) and clean up the idle loop somewhat while at
it (Rafael J Wysocki).
- Fix build problem in the cpufreq ppc driver (Geert Uytterhoeven).
- Allow the ACPI backlight driver module to be loaded if ACPI is
disabled which helps the i915 driver in those configurations
(stable-candidate) and change the code to help debug unusual use
cases (Chris Wilson).
- Wakeup IRQ management changes in v3.18 caused some drivers on the
at91 platform to trigger a warning from the IRQ core related to an
unexpected combination of interrupt action handler flags. However,
on at91 a timer IRQ is shared with some other devices (including
system wakeup ones) and that leads to the unusual combination of
flags in question.
To make it possible to avoid the warning introduce a new interrupt
action handler flag (which can be used by drivers to indicate the
special case to the core) and rework the problematic at91 drivers
to use it and work as expected during system suspend/resume. From
Boris Brezillon, Rafael J Wysocki and Mark Rutland.
- Clean up the generic power domains subsystem's debugfs interface
(Kevin Hilman)"

With certain restrictions it is possible for a wakeup device to share
an IRQ with an IRQF_NO_SUSPEND user, and the warnings introduced by
commit cab303be91dc47942bc25de33dc1140123540800 are spurious. The new
IRQF_COND_SUSPEND flag allows drivers to tell the core when these
restrictions are met, allowing spurious warnings to be silenced.
This patch documents how IRQF_COND_SUSPEND is expected to be used,
updating some of the text now made invalid by its addition.

The IRQF_NO_SUSPEND flag is intended to be used for interrupts required
to be enabled during the suspend-resume cycle. This mostly consists of
IPIs and timer interrupts, potentially including chained irqchip
interrupts if these are necessary to handle timers or IPIs. If an
interrupt does not fall into one of the aforementioned categories,
requesting it with IRQF_NO_SUSPEND is likely incorrect.
Using IRQF_NO_SUSPEND does not guarantee that the interrupt can wake the
system from a suspended state. For an interrupt to be able to trigger a
wakeup, it may be necessary to program various components of the system.
In these cases it is necessary to use {enable,disabled}_irq_wake.
Unfortunately, several drivers assume that IRQF_NO_SUSPEND ensures that
an IRQ can wake up the system, and the documentation can be read
ambiguously w.r.t. this property.
This patch updates the documentation regarding IRQF_NO_SUSPEND to make
this caveat explicit, hopefully making future misuse rarer. Cleanup of
existing misuse will occur as part of later patch series.

The PHY requires different settings for the Decision Feedback Analyzer
(DFE) when running in KX mode vs. KR mode. Update the code to change
these settings when changing modes in order to provide a more stable
link.
Additionally, adjust the 10GbE PQ skew default setting to a more sane
value.

atmel,idle-halt property should be used with care, it actually makes the
watchdog not counting when the CPU is in idle state, therefore the
watchdog reset time depends on mean CPU usage and will not reset at all
of the CPU stop working while it is in idle state, which is probably not
what you want.

The memcg control knobs indicate the highest possible value using the
symbolic name "infinity", which is long and awkward to type.
Switch to the string "max", which is just as descriptive but shorter and
sweeter.
This changes a user interface, so do it before the release and before
the development flag is dropped from the default hierarchy.

We (the Ocfs2 project) recently moved the location of our ocfs2-tools
git tree and project web page. The pertinent discussion can be seen
here:
https://oss.oracle.com/pipermail/ocfs2-devel/2015-February/010579.html
The following patch updates the Ocfs2 documentation in MAINTAINERS,
ocfs2.txt, and dlmfs.txt. I added our new official web page, changed
the location of our tools git tree and removed the link to Joel's
ancient kernel git tree - Andrew has handled our patches for a while
now.

Pull MIPS updates from Ralf Baechle:
"This is the main pull request for MIPS:
- a number of fixes that didn't make the 3.19 release.
- a number of cleanups.
- preliminary support for Cavium's Octeon 3 SOCs which feature up to
48 MIPS64 R3 cores with FPU and hardware virtualization.
- support for MIPS R6 processors.
Revision 6 of the MIPS architecture is a major revision of the MIPS
architecture which does away with many of original sins of the
architecture such as branch delay slots. This and other changes in
R6 require major changes throughout the entire MIPS core
architecture code and make up for the lion share of this pull
request.
- finally some preparatory work for eXtendend Physical Address
support, which allows support of up to 40 bit of physical address
space on 32 bit processors"
[ Ahh, MIPS can't leave the PAE brain damage alone. It's like
every CPU architect has to make that mistake, but pee in the snow
by changing the TLA. But whether it's called PAE, LPAE or XPA,
it's horrid crud - Linus ]

Make it possible to disable offloading writes by setting the optional
'submit_from_crypt_cpus' table argument.
There are some situations where offloading write bios from the
encryption threads to a single thread degrades performance
significantly.
The default is to offload write bios to the same thread because it
benefits CFQ to have writes submitted using the same IO context.

Use unbound workqueue by default so that work is automatically balanced

Add i2c-mux-idle-disconnect device tree property to PCA954x mux driver. The new

devices on the underlying buses might have same I2C addresses.

On Rockchip I2C the controller drops SDA low slightly too soon to meet
the "repeated start" requirements.
>From my own experimentation over a number of rates:
- controller appears to drop SDA at .875x (7/8) programmed clk high.
- controller appears to keep SCL high for 2x programmed clk high.
The first rule isn't enough to meet tSU;STA requirements in
Standard-mode on the system I tested on. The second rule is probably
enough to meet tHD;STA requirements in nearly all cases (especially
after accounting for the first), but it doesn't hurt to account for it
anyway just in case.
Even though the repeated start requirement only need to be accounted
for during a small part of the transfer, we'll adjust the timings for
the whole transfer to meet it. I believe that adjusting the timings
in just the right place to switch things up for repeated start would
require several extra interrupts and that doesn't seem terribly worth
it.
With this change and worst case rise/fall times, I see 100kHz i2c
going to ~85kHz. With slightly optimized rise/fall (800ns / 50ns) I
see i2c going to ~89kHz. Fast-mode isn't affected much because
tSU;STA is shorter relative to tHD;STA there.
As part of this change we needed to account for the SDA falling time.
The specification indicates that this should be the same, but we'll
follow Designware's lead and add a binding. Note that we deviate from
Designware and assign the default SDA falling time to be the same as
the SCL falling time, which is incredibly likely.

The number of clock cycles to be written into the CLKDIV register
that determines the I2C clk high phase includes the rise time.
So to meet the timing requirements defined in the I2C specification
which defines the minimal time SCL has to be high, the rise time
has to taken into account. The same applies to the low phase with
falling time.
In my test on RK3288-Pink2 board, which is not an upstream board yet,
if external pull-up resistor is 4.7K, rise_ns is about 700ns.
So the measured high_ns is about 3900ns, which is less than 4000ns
(the minimum high_ns in I2C specification for Standard-mode).
To fix this bug min_low_ns should include fall time and min_high_ns
should include rise time.
This patch merged the patch from chromium project which can get the
rise and fall times for signals from the device tree. This allows us
to more accurately calculate timings. see:

Pull clock framework updates from Mike Turquette:
"The clock framework changes contain the usual driver additions,
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
devices.
Additionally the framework core underwent a bit of surgery with two
major changes:
- The boundary between the clock core and clock providers (e.g clock
drivers) is now more well defined with dedicated provider helper
functions. struct clk no longer maps 1:1 with the hardware clock
but is a true per-user cookie which helps us tracker users of
hardware clocks and debug bad behavior.
- The addition of rate constraints for clocks. Rate ranges are now
supported which are analogous to the voltage ranges in the
regulator framework.
Unfortunately these changes to the core created some breakeage. We
think we fixed it all up but for this reason there are lots of last
minute commits trying to undo the damage"

Allwinner clock changes for 3.20
The set of clock changes for the 3.20 merge window, with mostly:
- Some PLL fixes for the A80 and A31
- The MMC custom phase functions are removed, and moved over to the generic
phase API.
- Add the A80 MMC clocks
Some DT changes slipped here as well, to preserve bisectability.

On the A80 SoC, the 4 mmc controllers each have a separate register
controlling their register access clocks and reset controls. These
registers in turn share a ahb clock gate and reset control.
This patch adds a platform device driver for these controls. It
requires both clocks and reset controls to be available, so using
CLK_OF_DECLARE might not be the best way.

The module 0 style clocks, or storage module clocks as named in the
official SDK, are almost the same as the module 0 clocks on earlier
Allwinner SoCs. The only difference is wider mux register bits.
As with earlier Allwinner SoCs, mmc module clocks are a special case
of mod0 clocks, with phase controls for 2 child clocks, output and
sample.
This patch adds support for both.
