Now that most platforms don't need disable_fiq and arch_ret_to_user
macros, we can remove the empty macros or empty entry-macro.S files.

Fix build breakage due to the following commits:
Commit bd5f12a247
ARM: 7042/3: mach-ep93xx: break out GPIO driver specifics
Commit 257af9f972
ARM: 7041/1: gpio-ep93xx: hookup the to_irq callback in the driver
The vision_ep9307 machine uses the ep93xx build-in gpios and needs to
include <mach/gpio-ep93xx.h> to pickup the defines.
The gpio_to_irq() call is now a callback to the gpio-ep93xx.c driver
and cannot be used as a constant initializer for the .irq member of
struct i2c_board_info.

Remove the now empty arch_reset() from all the mach/system.h includes,
and remove its callsite. Remove arm_machine_restart() as this function
no longer does anything useful.
For samsung platforms, remove the include of mach/system-reset.h and
plat/system-reset.h from their respective mach/system.h headers as these
just define their arch_reset functions. As a result, the s3c2410 and
plat-samsung system-reset.h files are no longer referenced, so remove
these files entirely.

IRQs are already disabled by the time arch_reset() is called, so these
calls to local_irq_disable() instead arch_reset() are redundant. Remove

Rather than marking the mach/gpio.h header files which want to use the
trivial GPIOLIB implementation, mark those which do not want to use it
instead. This means that by default, you get the trivial implementation
and only have to do something extra if you need to. This should
encourage the use of the trivial default implementation.
As an additional bonus, several gpio.h header files become empty.

The ep93xx DMA controller has 10 independent memory to peripheral (M2P)
channels, and 2 dedicated memory to memory (M2M) channels. M2M channels can
also be used by SPI and IDE to perform DMA transfers to/from their memory
mapped FIFOs.
This driver supports both M2P and M2M channels with DMA_SLAVE, DMA_CYCLIC and
DMA_MEMCPY (M2M only) capabilities.

The interrupt printing functionality in the ep93xx gpio debugfs function
does not behave as expected. It prints [interrupt] beside all pins which
are capable of being interrupts, not just those which are currently
configured as interrupts.
The best solution is just to remove the custom ep93xx gpio debugfs
function all together. The generic gpiolib one is good enough.

GPIO Ports A, B, and F on the ep93xx provide interrupt capability. It
is possible to debounce the input signal on these ports when interrupts
are enabled.
Support for this debounce capability was provided with an ep93xx internal

method and do not export the internal function.

The EP93xx C and D GPIO ports are multiplexed with the Keypad Interface
peripheral. At power-up they default into non-GPIO mode with the Key
Matrix controller enabled so these ports are unusable for GPIO. Note
that the Keypad Interface peripheral is only available in the EP9307,
EP9312, and EP9315 processor variants.
The keypad support will clear the DeviceConfig bits appropriately to
enable the Keypad Interface when the driver is loaded. And, when the
driver is unloaded it will set the bits to return the ports to GPIO mode.
To make these ports available for GPIO after power-up on all EP93xx
processor variants, set the KEYS and GONK bits in the DeviceConfig
register.
Similarly, the E, G, and H ports are multiplexed with the IDE Interface
peripheral. At power-up these also default into non-GPIO mode. Note
that the IDE peripheral is only available in the EP9312 and EP9315
processor variants.
Since an IDE driver is not even available in mainline, set the EONIDE,
GONIDE, and HONIDE bits in the DeviceConfig register so that these
ports will be available for GPIO use after power-up.

Rather than checking the MMU status in every instance of addruart, do it
once in kernel/debug.S, and change the existing addruart macros to
return both physical and virtual addresses. The main debug code can then
select the appropriate address to use.
This will also allow us to retreive the address of a uart for the MMU
state that we're not current in.

When channel_disable() is called, it disables per channel interrupts and
waits until channels state becomes STATE_STALL, and then disables the
channel. Now, if the DMA transfer is disabled while the channel is in
STATE_NEXT we will not wait anything and disable the channel immediately.
This seems to cause weird data corruption for example in audio transfers.
Fix is to wait while we are in STATE_NEXT or STATE_ON and only then
disable the channel.

Commit 7cfe24947 ("ARM: AMBA: Add pclk support to AMBA bus
infrastructure") changed AMBA bus to handle the PCLK automatically.
However, in EP93xx clock initialization is arch_initcall which is done
later than AMBA device identification. This causes
amba_get_enable_pclk() to fail resulting device where UARTs are not
functional.
So change ep93xx_clock_init() to be postcore_initcall.

This patch extends the ASoC API to allow sound cards to have more than one
CODEC and more than one platform DMA controller. This is achieved by dividing
some current ASoC structures that contain both driver data and device data into
structures that only either contain device data or driver data. i.e.
struct snd_soc_codec ---> struct snd_soc_codec (device data)
+-> struct snd_soc_codec_driver (driver data)
struct snd_soc_platform ---> struct snd_soc_platform (device data)
+-> struct snd_soc_platform_driver (driver data)
struct snd_soc_dai ---> struct snd_soc_dai (device data)
+-> struct snd_soc_dai_driver (driver data)
struct snd_soc_device ---> deleted
This now allows ASoC to be more tightly aligned with the Linux driver model and
also means that every ASoC codec, platform and (platform) DAI is a kernel
device. ASoC component private data is now stored as device private data.
The ASoC sound card struct snd_soc_card has also been updated to store lists
of it's components rather than a pointer to a codec and platform. The PCM
runtime struct soc_pcm_runtime now has pointers to all its components.
This patch adds DAPM support for ASoC multi-component and removes struct
snd_soc_socdev from DAPM core. All DAPM calls are now made on a card, codec
or runtime PCM level basis rather than using snd_soc_socdev.
Other notable multi-component changes:-
* Stream operations now de-reference less structures.
* close_delayed work() now runs on a DAI basis rather than looping all DAIs
in a card.
* PM suspend()/resume() operations can now handle N CODECs and Platforms
per sound card.
* Added soc_bind_dai_link() to bind the component devices to the sound card.
* Added soc_dai_link_probe() and soc_dai_link_remove() to probe and remove
DAI link components.
* sysfs entries can now be registered per component per card.
* snd_soc_new_pcms() functionailty rolled into dai_link_probe().
* snd_soc_register_codec() now does all the codec list and mutex init.
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform driver
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().
