This patch updates sdhci.h as Maurus suggestion like following:

From:
	#ifdef ...
	function()
	{
		blahblah;
	}
	#else
	function() { }
	#endif

To:

4b623926ba ARM: SAMSUNG: i2c/busses: Add HAVE_S3C2410_I2C option to include I2C for Samsung SoCs
This patch adds HAVE_S3C2410_I2C to control inclusion of I2C bus driver
on Samsung SoCs and makes I2C bus driver dependency SoC specific instead
of machine specific. This will enalbe all machines using Samsung ARCH_S3C2410,
_S3C64XX, _S5P6440, _S5PC100, and _S5PV210 to select the I2C driver by default

19206b1742 ARM: SAMSUNG: Add new s3c-sdhci card detection methods for Samsung SoCs
On some Samsung SoCs not all SDHCI controllers have card detect (CD)
line. For some embedded designs it is not even needed, because ususally
the device (like SDIO flash memory or wifi controller) is permanently
wired to the controller. There are also systems which have a card detect
line connected to some of the external interrupt lines or the presence
of the card depends on some other actions (like enabling a power
regulator).

This patch adds all required changes to platform support code, so
another patch, which extends the driver with support for the new card
detection methods can be applied.

and needed a cleanup, here it is:

1) Made every part modular, components are not built in if not selected.
2) Removed loads of preprocessor goo, mostly "#ifdef MACH_AKITA .... #endif" and
   similar code. The kernel size will grow by a few kb now, but the file is much
   more readable.
3) Reworked SD/CF power setting function and made it reentrant.
4) Add ISL6271A regulator support
5) Correctly register WM8750

6b23398591 omap mailbox: Set a device in logical mbox instance for traceability
With this patch, you'll get the following sysfs directories. This
structure implies that a single platform device, "omap2-mailbox" holds
multiple logical mbox instances. This could be the base to add sysfs
files for each logical mboxes. Then userland application can access a
mbox through sysfs entries if necessary(ex: setting kfifo size
dynamically)

b5bebe4102 omap: mailbox: convert block api to kfifo
The underlying buffering implementation of mailbox
is converted from block API to kfifo due to the simplicity
and speed of kfifo.

The default size of the kfifo buffer is set to 256 bytes.
This value is configurable at compile time (via
CONFIG_OMAP_MBOX_KFIFO_SIZE), and can be changed at
runtime (via the mbox_kfifo_size module parameter).

OMAP3530 CBB package can have GPIO126 muxed on 2 pins: mmc1_dat4 and
cam_strobe. This causes a problem with current multipath GPIO mux
handling, which muxes both pins as GPIO126 and makes the GPIO unusable.

Fix this by not muxing any pins if multipath GPIO is detected and
just print a warning instead. It's up to board files to set correct
mux using omap_mux_init_signal and pin name.

72a1179ed4 omap: dma: Support for prefetch in destination synchronizedtransfer
Omap DMA controller can prefetch data in advance in case of
destination synchronized data transfer. This may increase
performance when target HW block doesn't have fifo.
Data is waiting for transfer request in DMA fifo instead of read from memory.

Errata i202 (OMAP3430 - 1.12, OMAP3630 - 1.6):
UART module MDR1 register access can cause a dummy underrun
condition which could result in a freeze in the case of IrDA
communication or if used as UART, corrupted data.

Workaround is as follows for everytime MDR1 register is changed:
* setup all required UART registers
* setup MDR1.MODE_SELECT bit field
* Wait 5 L4 clk cycles + 5 UART functional clock cycles
* Clear the Tx and RX fifo using FCR register

Note: The following step is not done as I am assuming it is not
needed due to reconfiguration being done and there is no halted
operation perse.
* Read if required, the RESUME register to resume halted operation

Based on an earlier patch at:

000d534ed7 omap: rx51: Set regulator V28 always on
It seems that the battery cover sensor in Nokia N900 is powered from the
V28 domain. Now if this regulator is disabled it causes that the gpio 160
reads only zero which effectively causes uSD removal detection.

Currently the bootloader enabled V28 is kept on but this may change in the
future according to comment in
drivers/regulator/core.c: regulator_has_full_constraints.

Also if there are any consumers on the V28 domain doing regulator_enable
regulator_disable cycle the V28 will be disabled after that.

Prepare for these by defining the V28 as always_on regulator.

smp_processor_id() must not be called from a preemptible context (this

This lead to a problem where the wrong per_cpu kmap_high_l1_vipt_depth

kunmap_high_l1_vipt().

The solution is to move the call to smp_processor_id() after the call

79f64dbf68 ARM: 6273/1: Add barriers to the I/O accessors if ARM_DMA_MEM_BUFFERABLE
When the coherent DMA buffers are mapped as Normal Non-cacheable
(ARM_DMA_MEM_BUFFERABLE enabled), buffer accesses are no longer ordered
with Device memory accesses causing failures in device drivers that do
not use the mandatory memory barriers before starting a DMA transfer.
LKML discussions led to the conclusion that such barriers have to be
added to the I/O accessors:

http://thread.gmane.org/gmane.linux.kernel/683509/focus=686153
http://thread.gmane.org/gmane.linux.ide/46414
http://thread.gmane.org/gmane.linux.kernel.cross-arch/5250

This patch introduces a wmb() barrier to the write*() I/O accessors to
handle the situations where Normal Non-cacheable writes are still in the
processor (or L2 cache controller) write buffer before a DMA transfer
command is issued. For the read*() accessors, a rmb() is introduced
after the I/O to avoid speculative loads where the driver polls for a
DMA transfer ready bit.

Per the da850/omap-l138 Beta EVM SOM schematic, the DEFDCDC2 and
DEFDCDC3 lines are tied high. This leads to a 3.3V IO and 1.2V CVDD
voltage.

Pass the right platform data to the TPS6507x driver so it can operate
on the DEFDCDC{2,3}_HIGH register to read and change voltage levels.

3d3f78d752 ARM: call machine_shutdown() from machine_halt(), etc
x86 calls machine_shutdown() from the various machine_*() calls which
take the machine down ready for halting, restarting, etc, and uses
this to bring the system safely to a point where those actions can be
performed.  Such actions are stopping the secondary CPUs.

So, change the ARM implementation of these to reflect what x86 does.

This solves kexec problems on ARM SMP platforms, where the secondary
CPUs were left running across the kexec call.

5388a6b266 ARM: SMP: Always enable clock event broadcast support
The TWD local timers are unable to wake up the CPU when it is placed
into a low power mode, eg. C3.  Therefore, we need to adapt things
such that the TWD code can cope with this.

We do this by always providing a broadcast tick function, and marking
the fact that the TWD local timer will stop in low power modes.  This
means that when the CPU is placed into a low power mode, the core
timer code marks this fact, and allows an IPI to be given to the core.

9ca03a21e3 ARM: Factor out common code from cpu_proc_fin()
All implementations of cpu_proc_fin() start by disabling interrupts
and then flush caches.  Rather than have every processors proc_fin()
implementation do this, move it out into generic code - and move the
cache flush past setup_mm_for_reboot() (so it can benefit from having
caches still enabled.)

This allows cpu_proc_fin() to become independent of the L1/L2 cache
types, and eventually move the L2 cache flushing into the L2 support
code.

On ARM one Linux PGD entry contains two hardware entries (see page

fill both L1 entries. But create_mapping() doesn't follow the rule.
It can create inidividual L1 entries, so here we have to call
pmd_none() check in do_translation_fault() for the entry really
corresponded to address, not for the first of pair.

5bc23d32d8 ARM: DMA coherent allocator: align remapped addresses
The DMA coherent remap area is used to provide an uncached mapping
of memory for coherency with DMA engines.  Currently, we look for
any free hole which our allocation will fit in with page alignment.

However, this can lead to fragmentation of the area, and allows small
allocations to cross L1 entry boundaries.  This is undesirable as we
want to move towards allocating sections of memory.

Align allocations according to the size, limiting the alignment between
the page and section sizes.

1dbd30e989 ARM: 6225/1: make TCM allocation static and common for all archs
This changes the TCM handling so that a fixed area is reserved at
0xfffe0000-0xfffeffff for TCM. This areas is used by XScale but
XScale does not have TCM so the mechanisms are mutually exclusive.

This change is needed to make TCM detection more dynamic while
still being able to compile code into it, and is a must for the
unified ARM goals: the current TCM allocation at different places
in memory for each machine would be a nightmare if you want to
compile a single image for more than one machine with TCM so it
has to be nailed down in one place.

fb8ce14c7e OMAP: PM constraints: add omap_pm_set_min_clk_rate()
Add omap_pm_set_min_clk_rate().  This constraint is meant for use by
device drivers to translate a certain device-specific performance
constraint (e.g., "minimum polygons per second") to a clock rate for
the driver's device, given the driver's intimate knowledge of the
device hardware (e.g., device type, device hardware revision, firmware
revision, etc.)  From a general PM core perspective, clock rate is
probably the closest general analog to "performance" that is
available, but the exact mapping from a use-case-specific performance
constraint to clock rate must be done by the driver.  Drivers intended for
upstream merging shouldn't hardcode specific clock rates in their code
without basing those rates on some performance criteria requested through
the driver's subsystem (ideally, from userspace).

Imre Deak <imre.deak@nokia.com> described the need and use-case for
this constraint, and discussed the implementation - thanks, Imre.
