The values of n, m1 and m2 needs to be subtracted by 2 before writing them to
the FP register. The dot clock calculation already thinks of these values in
register form so we must also specify them as such.

Pull ARM virtualization changes:
"This contains parts of the ARM KVM support that have dependencies on
other patches merged through the arm-soc tree. In combination with
patches coming through Russell's tree, this will finally add full
support for the kernel based virtual machine on ARM, which has been
awaited for some time now.
Further, we now have a separate platform for virtual machines and qemu
booting that is used by both Xen and KVM, separating these from the
Versatile Express reference implementation. Obviously, this new
platform is multiplatform capable so it can be combined with existing
machines in the same kernel."

There is simply no reason to be manually setting the private driver
data to NULL in the remove/fail to probe cases. This is just extra
cruft code that can be removed.
A few notes:
* Nothing relies on drvdata being set to NULL.
* The __device_release_driver() function eventually calls
dev_set_drvdata(dev, NULL) anyway, so there's no need to do it
twice.
* I verified that there were no cases where xxx_get_drvdata() was
being called in these drivers and checking for / relying on the NULL
return value.
This could be cleaned up kernel-wide but for now just take the baby
step and remove from the i2c subsystem.

Pull sh-mobile pinctrl conversion from Arnd Bergmann:
"This is another cleanup series, containing the move of the Renesas
SH-Mobile pin controller code from arch/arm/mach-shmobile over to the
generic pinctrl subsystem, changing it over to the common interfaces
in the process.
Based on agreement between Olof, Paul Mundt, Linus Walleij and Simon,
we're merging this large branch of pinctrl conversion through arm-soc,
even though it contains the corresponding conversions for arch/sh.
Main reason for this is tight dependencies (that will now mostly be
broken) between the arch/sh and mach-shmobile implementations.
There will be more of this in 3.10 to do device-tree bindings, but
this is the initial conversion."

Pull ARM SoC cleanups from Arnd Bergmann:
"A large number of cleanups, all over the platforms. This is dominated
largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
others moving code out of arch/arm into more appropriate subsystems.
The clocksource and irqchip drivers are now abstracted to the point
where platforms that are already cleaned up do not need to even
specify the driver they use, it can all get configured from the device
tree as we do for normal device drivers. The clocksource changes
basically touch every single platform in the process.
We further clean up the use of platform specific header files here,
with the goal of turning more of the platforms over to being
"multiplatform" enabled, which implies that they cannot expose their
headers to architecture independent code any more.
It is expected that no functional changes are part of the cleanup.
The overall reduction in total code lines is mostly the result of
removing broken and obsolete code."

We trim the fb to fit the CRTC by computing the offset of that CRTC to
its nearest tile_row origin. This allows us to use framebuffers that are
larger than the CRTC limits without additional work.
However, we failed to compute the offset for a linear framebuffer
correctly as we treated its x-advance in whole tiles (instead of the
linear increment expected), leaving the CRTC misaligned with its
contents.

This patch enhances the IB core support for Memory Windows (MWs).
MWs allow an application to have better/flexible control over remote
access to memory.
Two types of MWs are supported, with the second type having two flavors:
Type 1 - associated with PD only
Type 2A - associated with QPN only
Type 2B - associated with PD and QPN
Applications can allocate a MW once, and then repeatedly bind the MW
to different ranges in MRs that are associated to the same PD. Type 1
windows are bound through a verb, while type 2 windows are bound by
posting a work request.
The 32-bit memory key is composed of a 24-bit index and an 8-bit
key. The key is changed with each bind, thus allowing more control
over the peer's use of the memory key.
The changes introduced are the following:
* add memory window type enum and a corresponding parameter to ib_alloc_mw.
* type 2 memory window bind work request support.
* create a struct that contains the common part of the bind verb struct
ibv_mw_bind and the bind work request into a single struct.
* add the ib_inc_rkey helper function to advance the tag part of an rkey.
Consumer interface details:
* new device capability flags IB_DEVICE_MEM_WINDOW_TYPE_2A and
IB_DEVICE_MEM_WINDOW_TYPE_2B are added to indicate device support
for these features.
Devices can set either IB_DEVICE_MEM_WINDOW_TYPE_2A or
IB_DEVICE_MEM_WINDOW_TYPE_2B if it supports type 2A or type 2B
memory windows. It can set neither to indicate it doesn't support
type 2 windows at all.
* modify existing provides and consumers code to the new param of
ib_alloc_mw and the ib_mw_bind_info structure

Highlights:
- Unification of HD-audio parser code (aka generic parser)
- Support of new Intel HD-audio controller, new IDT codecs
- Fixes for HD-audio HDMI audio hotplug
- Haswell HDMI audio fixup
- Support of Creative CA0132 DSP code
- A few fixes of HDSP driver
- USB-audio fix for Roland A-PRO, M-Audio FT C600
- Support PM for aloop driver (and fixes Oops)
- Compress API updates for gapless playback support
For ASoC part:
- Support for a wider range of hardware in the compressed stream code
- The ability to mute capture streams as well as playback streams
while inactive
- DT support for AK4642, FSI, Samsung I2S and WM8962
- AC'97 support for Tegra
- New driver for max98090, replacing the stub which was there
- A new driver from Dialog
Note that due to dependencies, DTification of DMA support for Samsung
platforms (used only by the and I2S driver and SPI) is merged here as
well."

APEI GHES and i7core_edac/sb_edac currently can be loaded at
the same time, but those are Highlander modules:
"There can be only one".
There are two reasons for that:
1) Each driver assumes that it is the only one registering at
the EDAC core, as it is driver's responsibility to number
the memory controllers, and all of them start from 0;
2) If BIOS is handling the memory errors, the OS can't also be
doing it, as one will mangle with the other.
So, we need to add an module owner's lock at the EDAC core,
in order to avoid having two different modules handling memory
errors at the same time. The best way for doing this lock seems
to use the driver's name, as this is unique, and won't require
changes on every driver.

Create a debugfs direcotry i5100_edac/mcX for each memory controller and
add nodes to control how fault injection is preformed.
After configuring an injection using inject_channel, inject_deviceptr1,
inject_deviceptr2, inject_eccmask1, inject_eccmask2 and inject_hlinesel
trigger the injection by writing anything to inject_enable.
Example of a CE injection:
echo 0 > /sys/kernel/debug/i5100_edac/mc0/inject_channel
echo 1 > /sys/kernel/debug/i5100_edac/mc0/inject_hlinesel
echo 61440 > /sys/kernel/debug/i5100_edac/mc0/inject_eccmask1
echo 1 > /sys/kernel/debug/i5100_edac/mc0/inject_enable
Example of UE injection:
echo 0 > /sys/kernel/debug/i5100_edac/mc0/inject_channel
echo 2 > /sys/kernel/debug/i5100_edac/mc0/inject_hlinesel
echo 65535 > /sys/kernel/debug/i5100_edac/mc0/inject_eccmask1
echo 65535 > /sys/kernel/debug/i5100_edac/mc0/inject_eccmask2
echo 17 > /sys/kernel/debug/i5100_edac/mc0/inject_deviceptr1
echo 0 > /sys/kernel/debug/i5100_edac/mc0/inject_deviceptr2
echo 1 > /sys/kernel/debug/i5100_edac/mc0/inject_enable
Sometimes it is needed to enable the injection more then once (echo to
the inject_enable node) for the injection to happen, I am not sure why.

After running a series of tests on an HP DL320, filled with different
memory sizes, it was noticed that, when filled with just one DIMM
on such hardware, the driver wrongly detects twice the memory, and
thinks that both channels 0 and 1 are filled.
It seems to be partially caused by the BIOS and partially by the driver.
The i3200_edac current logic would be working fine if the BIOS were
disabling the unused second channel when just one DIMM is connected,
in order to do power-saving, as recommended on this chipset's datasheet.
However, the BIOS on this particular machine doesn't do it:
[ 16.741421] EDAC DEBUG: how_many_channels: In dual channel mode
[ 16.741424] EDAC DEBUG: how_many_channels: 2 DIMMS per channel enabled
So, the driver were assuming that 2 channels are enabled (well, they are,
but the second is unused).
Combined with that, I found two issues at the logic that creates the
EDAC data, that were failing when the two channels are not equally
filled (AFAICT, that happens only when just 1 DIMM is plugged).
The first one is that a 0 at DRB means that nothing is filled. The
driver's logic, however, do some calculation with that.
The second one is that the logic that fills the DIMM data currently
assumes that both channels are equally filled.
I tested the system already with the current configuration and my
patch and it is now working fine. So, for a 2R single DIMM 2Gb memory
at dimm slot 01 (channel 0), it is now displaying:
[ 16.741406] EDAC DEBUG: i3200_get_drbs: drb[0][0] = 16, drb[1][0] = 0
[ 16.741410] EDAC DEBUG: i3200_get_drbs: drb[0][1] = 32, drb[1][1] = 0
[ 16.741413] EDAC DEBUG: i3200_get_drbs: drb[0][2] = 32, drb[1][2] = 0
[ 16.741416] EDAC DEBUG: i3200_get_drbs: drb[0][3] = 32, drb[1][3] = 0
...
[ 16.741896] EDAC DEBUG: i3200_probe1: csrow 0, channel 0, size = 1024 Mb
[ 16.741899] EDAC DEBUG: i3200_probe1: csrow 1, channel 0, size = 1024 Mb
and the corresponding sysfs nodes are now properly filled.

Currently, it is not possible to know, when debug is enabled,
if the driver is using 2 DIMMS per channel mode or not. It is
not possible to know the values of the drbs registers, used
