This branch contains a largeish set of updates of power management and
clock setup. The bulk of it is for OMAP/AM33xx platforms, but also a
few around hotplug/suspend/resume on Exynos.
It includes a split-up of some of the OMAP clock data into separate
files which adds to the diffstat, but gross delta is fairly reasonable.

Here are more patches in the progression towards multiplatform, sparse
irq conversions in particular.
Tegra has a handful of cleanups and general groundwork, but is
not quite there yet on full enablement.
Platforms that are enabled through this branch are VT8500 and Zynq. note
that i.MX was converted in one of the earlier cleanup branches as
well (before we started a separate topic for multiplatform). And both
new platforms for this merge window, sunxi and bcm, were merged with
multiplatform support enabled.

This contains the bulk of new SoC development for this merge window.
Two new platforms have been added, the sunxi platforms (Allwinner A1x
SoCs) by Maxime Ripard, and a generic Broadcom platform for a new
series of ARMv7 platforms from them, where the hope is that we can
keep the platform code generic enough to have them all share one mach
directory. The new Broadcom platform is contributed by Christian Daudt.
Highbank has grown support for Calxeda's next generation of hardware,
ECX-2000.
clps711x has seen a lot of cleanup from Alexander Shiyan, and he's also
taken on maintainership of the platform.
Beyond this there has been a bunch of work from a number of people on
converting more platforms to IRQ domains, pinctrl conversion, cleanup
and general feature enablement across most of the active platforms.

Signed-off-by: Olof Johansson <olof@lixom.net>
Based on earlier discussions[1] we attempted to find a suitable
location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP:
DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion
to dmaengine is complete.
Unfortunately that was before I was able to try to test compile
of the ARM multiplatform builds for omap2+, and the end result
was not very good.
So I'm creating yet another all over the place patch to cut the
last dependency for building omap2+ for ARM multiplatform. After
this, we have finally removed the driver dependencies to the
arch/arm code, except for few drivers that are being worked on.
The other option was to make the <plat-omap/dma-omap.h> path
to work, but we'd have to add some new header directory to for
multiplatform builds.
Or we would have to manually include arch/arm/plat-omap/include
again from arch/arm/Makefile for omap2+.
Neither of these alternatives sound appealing as they will
likely lead addition of various other headers exposed to the
drivers, which we want to avoid for the multiplatform kernels.
Since we already have a minimal include/linux/omap-dma.h,
let's just use that instead and add a note to it to not
use the custom omap DMA functions any longer where possible.
Note that converting omap DMA to dmaengine depends on
dmaengine supporting automatically incrementing the FIFO
address at the device end, and converting all the remaining
legacy drivers. So it's going to be few more merge windows.

This patch fixes errors seen in identifying old Samsung SLC, due to the
following commits:
commit e2d3a35ee4
mtd: nand: detect Samsung K9GBG08U0A, K9GAG08U0F ID
commit e3b88bd604
mtd: nand: add generic READ ID length calculation functions
Some Samsung NAND with "5-byte" ID really appear to have 6-byte IDs, with
wraparound like:
Samsung K9K8G08U0D
ec d3 51 95 58 ec ec d3
Samsung K9F1G08U0C
ec f1 00 95 40 ec ec f1
Samsung K9F2G08U0B
ec da 10 95 44 00 ec da
This bad wraparound makes it hard to reliably detect the difference
between Samsung SLC with 5-byte ID and Samsung SLC with 6-byte ID.
The fix is to, for now, only use the new Samsung table for MLC. We
cannot support the new SLC (K9FAG08U0M) until Samsung gives better ID
decode information.
Note that this applies in addition to the previous regression fix:
commit bc86cf7af2
mtd: nand: fix Samsung SLC NAND identification regression
Together, these patches completely restore the previous detection
behavior so that we cannot see any more regressions in Samsung SLC NAND
(finger crossed). With luck, I can get a hold of a Samsung
representative and stop having to cross my fingers eventually.

A combination of the following two commits caused a regression in 3.7-rc1
when identifying some Samsung NAND, so that some previously working NAND
were no longer detected properly:
commit e3b88bd604
mtd: nand: add generic READ ID length calculation functions
commit e2d3a35ee4
mtd: nand: detect Samsung K9GBG08U0A, K9GAG08U0F ID
Particularly, a regression was seen on Samsung K9F2G08U0B, with the
following full 8-byte READ ID string:
ec da 10 95 44 00 ec da
The basic problem is that Samsung manufactures both SLC and MLC NAND
that use a non-standard decoding table for deriving information from
their IDs. I have heuristically determined that all the chips that use
the new table have ID strings which wrap around after the 6th byte.
Unfortunately, I overlooked the fact that some older Samsung SLC (which
use a different decoding table) have "5 byte ID strings" which also wrap
around after the 6th byte.
This patch re-introduces a distinction between these old and new Samsung
NAND by checking that the 6th byte is non-zero, allowing both old and
new Samsung NAND to be detected properly.

This moves the MTU timer driver from arch/arm/plat-nomadik
to drivers/clocksource and moves the header file to the
platform_data directory.
As this moves the last file being compiled to an object out
of arch/arm/plat-nomadik, we have to "turn off the light"
and delete the plat-nomadik directory, because it is not
allowed to have an empty Makefile in a plat-* directory.
This is probably also a desired side effect of depopulating
the arch/arm directory of drivers. Luckily we have just
deleted all the <plat/*> include files prior to this so
by moving the last one we may delete the directory.
After this all the Ux500 and Nomadik device drivers live
outside of the arch/arm hierarchy.

Modify the device PM QoS core code to support PM QoS flags requests.
First, add a new field of type struct pm_qos_flags called "flags"
to struct dev_pm_qos for representing the list of PM QoS flags
requests for the given device. Accordingly, add a new "type" field
to struct dev_pm_qos_request (along with an enum for representing
request types) and a new member called "flr" to its data union for
representig flags requests.
Second, modify dev_pm_qos_add_request(), dev_pm_qos_update_request(),
the internal routine apply_constraint() used by them and their
existing callers to cover flags requests as well as latency
requests. In particular, dev_pm_qos_add_request() gets a new
argument called "type" for specifying the type of a request to be
added.
Finally, introduce two routines, __dev_pm_qos_flags() and
dev_pm_qos_flags(), allowing their callers to check which PM QoS
flags have been requested for the given device (the caller is
supposed to pass the mask of flags to check as the routine's
second argument and examine its return value for the result).

This is a pretty significant branch. It's the introduction of the
first multiplatform support on ARM, and with this (and the later
branch) merged, it is now possible to build one kernel that contains
support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
platforms will be convered over in the next few releases.
Two critical last things had to be done for this to be practical and
possible:
* Today each platform has its own include directory under
mach-<mach>/include/mach/*, and traditionally that is where a lot of
driver/platform shared definitions have gone, such as platform data
structures. They now need to move out to a common location instead,
and this branch moves a large number of those out to
include/linux/platform_data.
* Each platform used to list the device trees to compile for its
boards in mach-<mach>/Makefile.boot.
Both of the above changes will mean that there are some merge
conflicts to come (and some to resolve here). It's a one-time move and
once it settles in, we should be good for quite a while. Sorry for the
overhead.

Pull ARM soc multiplatform enablement from Olof Johansson:
"This is a pretty significant branch. It's the introduction of the
first multiplatform support on ARM, and with this (and the later
branch) merged, it is now possible to build one kernel that contains
support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
platforms will be convered over in the next few releases.
Two critical last things had to be done for this to be practical and
possible:
* Today each platform has its own include directory under
mach-<mach>/include/mach/*, and traditionally that is where a lot
of driver/platform shared definitions have gone, such as platform
data structures. They now need to move out to a common location
instead, and this branch moves a large number of those out to
include/linux/platform_data.
* Each platform used to list the device trees to compile for its
boards in mach-<mach>/Makefile.boot.
Both of the above changes will mean that there are some merge
conflicts to come (and some to resolve here). It's a one-time move
and once it settles in, we should be good for quite a while. Sorry
for the overhead."
Fix conflicts as per Olof.

Datasheets for the following Samsung NAND parts (both MLC and SLC) describe
extensions to the Samsung 6-byte extended ID decoding table:
K9GBG08U0A (MLC, 6-byte ID)
K9GAG08U0F (MLC, 6-byte ID)
K9FAG08U0M (SLC, 6-byte ID)
The table found in K9GAG08U0F, p.44, contains a superset of the information
found in other previous datasheets.
This patch adds support for all of these chips, with 512B and 640B OOB sizes.
It also changes the detection pattern such that this table applies to all
Samsung 6-byte ID NAND, not just MLC. This is safe, according to the NAND
parameter data I have collected:
Note that nand_base.c does not yet support the bad block marker scheme defined
for these chips (i.e., scan 1st and last page for BB markers).

When decoding the extended ID bytes of a NAND chip, we have to calculate the ID
length according to some heuristic patterns (e.g., Does the ID wrap around?
Does it end in trailing zeros?). Currently, these heuristics are built into
complicated if/else blocks that can be hard to understand.
Now, these checks can be done generically in a function, making them more
robust and reusable. In fact, this sort of calculation is needed in future
additions to nand_base.c. And with this advancement, we get the added benefit
of a more readable "extended ID decode".

When the frequency on the nand chip pins is above 33MHz,
the nand EDO(extended Data Out) timing could be applied.
The GPMI implements a Feedback read strobe to sample the read data in
the EDO timing mode.
This patch adds the EDO feature for the gpmi-nand driver.
For some onfi nand chips, the mode 4 is the fastest;
while for other onfi nand chips, the mode 5 is the fastest.
This patch only adds the support for the fastest asynchronous timing mode.
So this patch only supports the mode 4 and mode 5.
I tested several Micron's ONFI nand chips with EDO enabled,
take Micron MT29F32G08MAA for example (in mode 5, 100MHz):
1) The test result BEFORE we add the EDO feature:
=================================================

mtd_speedtest: MTD device size 209715200, eraseblock size 524288,
page size 4096, count of eraseblocks 400,
pages per eraseblock 128, OOB size 218

2) The test result AFTER we add the EDO feature:

mtd_speedtest: MTD device: 2
mtd_speedtest: MTD device size 209715200, eraseblock size 524288,

The default frequencies of the extra clocks are 200MHz.
The current code sets the extra clocks to 44.5MHz.
When i add the EDO feature to gpmi, i have to revert the extra clocks
to 200MHz.
So it is better that we do not set the default values for the extra
clocks. The driver runs well even when we do not set the default values for
extra clocks.
