The Cragganmore system is modular with I2C based identification chips on
the system allowing identification of the system build. Provide a stub I2C
driver which parses the module IDs and uses them to select the appropriate
audio subsystem components to register. To avoid confusion due to having
the mini-driver in the system the driver is placed in a separate file.

This patch adds common DMA operations which are used for Samsung DMA
drivers. Currently there are two types of DMA driver for Samsung SoCs.
The one is S3C-DMA for S3C SoCs and the other is PL330-DMA for S5P SoCs.
This patch provides funcion pointers for common DMA operations to DMA
client driver like SPI and Audio. It makes DMA client drivers support
multi-platform.
In addition, this common DMA operations implement the shared actions
that are needed for DMA client driver. For example shared actions are
filter() function for dma_request_channel() and parameter passing for
device_prep_slave_sg().

Rather than marking the mach/gpio.h header files which want to use the

encourage the use of the trivial default implementation.

There are SoCs where attempting to enter a low power state is ignored,
and the CPU continues executing instructions with all state preserved.
It is over-complex at that point to disable the MMU just to call the
resume path.
Instead, allow the suspend finisher to return error codes to abort
suspend in this circumstance, where the cpu_suspend internals will then
unwind the saved state on the stack. Also omit the tlb flush as no

This makes all the functions that use the shift slightly smaller, one
instruction in most cases but more for ack() and maskack().

Kernel 2.6.37 adds new interrupt methods which take a struct irq_data
rather than an irq number. Conver S3C64xx irq-eint to use this with a
simple textual substitution.

Kernel 2.6.37 adds new interrupt methods which take a struct irq_data
rather than an irq number. Begin converting Samsung platforms over to
these methods by converting s3c_irqext_wake() with a simple textual
substitution.

Needed to update to apply fixes for which the old branch was too
outdated.
Don't rewrite clock config in UCON preconfigured by
bootloader. No need to set 10th bit in UCON because
[11:10] 2'b00 means source clock is PCLK too.
If set, console does not work if bootloader
has preconfigured [11:10] with 2'b00.
If not set, console works with any bootloader
config value (2'bxx).
More information about clock setup in UCON is available
in "S3C6410X RISC Microprocessor User's Manual,
Revision 1.20" p. 31-13 (Chapter 31.6.2
UART CONTROL REGISTER).

Call the AC97 controller devices found in S3C, S5P and newer
SoCs as 'samsung-ac97' rather than 's3c-ac97'.

The ASoC uses common DMA driver for Audio devices. So it makes
sense to a common audio-dma device shared across all platforms.

Some Samsung SoCs have a PCM(DSP) controller. So the name
s3c24xx-pcm-audio for DMA driver is not very appropraite.
This patch moves :-
s3c24xx-pcm-audio -> samsung-audio

Since the I2S of S3C64XX and newer SoCs are incremental
versions of each other with changes managable in a single
driver, rename the 's3c64xx-iis' -> 'samsung-i2s'
