This patch makes GPIO pin to INTERRUPT mode or INPUT mode according
to bitmap_gpio_int. When the related bit of bitmap_gpio_int is set,
it makes GPIO pin to INTERRUPT mode instrad of INPUT mode in the
samsung_gpiolib_4bit_input function.

When a device uses GPIO interrupt, its driver assumes that GPIO
should be INPUT mode. However, GPIO of SAMSUNG SoC is sepated to
INPUT mode and INTERRUPT mode. They are set by 0x0 and 0xF in GPIO
control register. If the register is set to INPUT mode, the
interrupt never occur. Therefore, it's necessary to set INTERRUPT
mode instead of INPUT mode when the pin is used for GPIO interrupt.
This patch inserts the bitmap_gpio_int member in struct samsung_
gpio_chip in order to represent use of GPIO interrupt for each pin
and sets the related bit when s5p_register_gpio_interrupt function
is called.

Presently there are three peripherals that gets it timing
by runtime calculation. Those peripherals can work with
frequency scaling that affects gpmc clock. But timing
calculation for them are in different ways.
Here a generic runtime calculation method is proposed. Input
to this function were selected so that they represent timing
variables that are present in peripheral datasheets. Motive
behind this was to achieve DT bindings for the inputs as is.
Even though a few of the tusb6010 timings could not be made
directly related to timings normally found on peripherals,
expressions used were translated to those that could be
justified.
There are possibilities of improving the calculations, like
calculating timing for read & write operations in a more
similar way. Expressions derived here were tested for async
onenand on omap3evm (as vanilla Kernel does not have omap3evm
onenand support, local patch was used). Other peripherals,
tusb6010, smc91x calculations were validated by simulating
on omap3evm.
Regarding "we_on" for onenand async, it was found that even
for muxed address/data, it need not be greater than
"adv_wr_off", but rather could be derived from write setup
time for peripheral from start of access time, hence would
more be in line with peripheral timings. With this method
it was working fine. If it is required in some cases to
have "we_on" same as "wr_data_mux_bus" (i.e. greater than
"adv_wr_off"), another variable could be added to indicate
it. But such a requirement is not expected though.
It has been observed that "adv_rd_off" & "adv_wr_off" are
currently calculated by adding an offset over "oe_on" and
"we_on" respectively in the case of smc91x. But peripheral
datasheet does not specify so and so "adv_rd(wr)_off" has
been derived (to be specific, made ignorant of "oe_on" and
"we_on") observing datasheet rather than adding an offset.
Hence this generic routine is expected to work for smc91x
(91C96 RX51 board). This was verified on smsc911x (9220 on
OMAP3EVM) - a similar ethernet controller.
Timings are calculated in ps to prevent rounding errors and
converted to ns at final stage so that these values can be
directly fed to gpmc_cs_set_timings(). gpmc_cs_set_timings()
would be modified to take ps once all custom timing routines
are replaced by the generic routine, at the same time
generic timing routine would be modified to provide timings
in ps. struct gpmc_timings field types are upgraded from
u16 => u32 so that it can hold ps values.
Whole of this exercise is being done to achieve driver and
DT conversion. If timings could not be calculated in a
peripheral agnostic way, either gpmc driver would have to
be peripheral gnostic or a wrapper arrangement over gpmc
driver would be required.

Configure busturnaround, cycle2cycledelay, waitmonitoringtime,
clkactivationtime in gpmc_cs_set_timings(). This is done so
that boards can configure these parameters of gpmc in Kernel
instead of relying on bootloader. Also configure bool type
timings like extradelay.
This needed change to the existing users that were configuring
clk activation time and extra delay by directly writing to
registers. Thanks to Tony for making me aware of users of clk
activation and being kind enough to test the modified one.

Pull ARM SoC power management and clock changes from Olof Johansson:
"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."

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/pm2
From Tony Lindgren:
Remaining patches to allow omap2+ to build with multiplatform
enabled. Unfortunately the DMA header patch had to be redone
to avoid adding new multiplatform specific include paths, the
other patches are just trivial compile fixes.
Note that this does not yet contain the necessary Kconfig
changes as we are still waiting for some drivers to get
fixed up first.

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.

When booting with DT the OF core can fill up the resources provided within
the DT blob.
The current way of handling the DT boot prevents us from removing hwmod data
for platforms only suppose to boot with DT (OMAP5 for example) since we need
to keep the whole hwmod database intact in order to have more resources in
hwmod than in DT (to be able to append the DMA resource from hwmod).
To fix this issue we just examine the OF provided resources:
If we do not have resources we use hwmod to fill them.
If we have resources we check if we already able to recive DMA resource, if
no we only append the DMA resurce from hwmod to the OF provided ones.
In this way we can start removing hwmod data for devices which have their
resources correctly configured in DT without regressions.

Some PRM functions will need to be called by the hwmod code early in
kernel init. To handle this, split the PRM initialization code into
early and late phases. The early init is handled via mach-omap2/io.c,
while the late init is handled by subsys_initcall().

From Tony Lindgren <tony@atomide.com>:
Common clock framework for omap2+ via Paul Walmsley <paul@pwsan.com>:
Convert the OMAP2+ clock code and data to rely on the common
clock framework for internal bookkeeping and the driver API.
Basic test logs for this branch on top of Tony's cleanup-prcm branch
at commit c9d501e5cb0238910337213e12a09127221c35d8 are here:
http://www.pwsan.com/omap/testlogs/common_clk_devel_3.8_rebase/20121112192516/
However, cleanup-prcm at c9d501e5 does not include some fixes
that are needed for a successful test. With several reverts,
fixes, and workarounds applied, the following test logs were
obtained:
http://www.pwsan.com/omap/testlogs/TEST_common_clk_devel_3.8_rebase/20121112192300/
which indicate that the series tests cleanly.
N.B. The common clock data addition patches result in many
checkpatch warnings of the form "WARNING: static const char *
array should probably be static const char * const". However, it
appears that resolving these would require changes to the CCF
itself. So the resolution of these warnings is being postponed
until that can be coordinated.
These patches result in a ~55KiB increase in runtime kernel memory
usage when booting omap2plus_defconfig kernels.
Conflicts:
arch/arm/mach-omap2/clock33xx_data.c
arch/arm/mach-omap2/clock3xxx_data.c
arch/arm/mach-omap2/clock44xx_data.c
Note that this is based on a merge of the omap-for-v3.8/cleanup-prcm
and omap-for-v3.8/pm as otherwise merged in with the pm changes it
would automatically resolve into a non-booting merge for omap3 as
the smartreflex clock names were changed in the pm branch.
