ASoC: samsung: Use iio_get_channel_type() accessor.
struct iio_chan_spec is meant to be opaque to IIO consumer drivers
which should only use the interfaces in linux/iio/consumer.h.
Use the provided accessor function to find get the type of the
channel instead of directly reading it form the structure.

ASoC: Refactor non_legacy_dai_naming flag
Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:

Historically, the legacy DAI naming scheme was applied to platform
drivers and the newer scheme to CODEC drivers. During componentisation
the core lost the knowledge of if a driver was a CODEC or platform, they
were all now components. To continue to support the legacy naming on
older platform drivers a flag was added to the snd_soc_component_driver
structure, non_legacy_dai_naming, to indicate to use the new scheme and
this was applied to all CODECs as part of the migration.

However, a slight issue appears to be developing with respect to this
flag being opt in for the non-legacy scheme, which presumably we want to
be the primary scheme used. Many codec drivers appear to forget to
include this flag:

  grep -l -r "snd_soc_component_driver" sound/soc/codecs/*.c |
  xargs grep -L "non_legacy_dai_naming" | wc
     48      48    556

Whilst in many cases the configuration of the DAIs themselves will cause
the core to apply the new scheme anyway, it would seem more sensible to
change the flag to legacy_dai_naming making the new scheme opt out. This
patch series migrates across to such a scheme.

Specify clock provider directly to CPU DAIs
Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:

Currently the set_fmt callback always passes clock provider/consumer
with respect to the CODEC. This made sense when the framework was
directly broken down into platforms and CODECs. However, as things
are now broken down into components which can be connected as either
the CPU or CODEC side of a DAI link it simplifies things if each
side of the link is just told if it is provider or consumer of the
clocks. Making this change allows us to remove one of the last parts
of the ASoC core that needs to know if a driver is a CODEC driver,
where it flips the clock format specifier if a CODEC driver is used on
the CPU side of a DAI link, as well as just being conceptually more
consistent with componentisation.

The basic idea of this patch chain is to change the set_fmt callback
from specifying if the CODEC is provider/consumer into directly
specifying if the component is provider/consumer. To do this we add
some new defines, and then to preserve bisectability, the migration is
done by adding a new callback, converting over all existing CPU side
drivers, converting the core, and then finally reverting back to the
old callback.

Converting the platform drivers makes sense as the existing defines
are from the perspective of the CODEC and there are more CODEC drivers
than platform drivers.

Obviously a fair amount of this patch chain I was only able to build
test, so any testing that can be done would be greatly appreciated.

The args is a stack variable, so it could have junk (uninitialized)
therefore args.np could have a non-NULL and random value even though
property was missing. Later could trigger invalid pointer dereference.

There's no need to check for args.np because args.np won't be
initialized on errors.

Big cleanup for the Samsung S3C24xx and S3C64xx platforms, although it
 also touches files shared with S5Pv210 and Exynos.  This is mostly Arnd
 Bergmann work which Krzysztof Kozlowski took over, rebased and polished.
 
 The goal is to cleanup, merge and finally make the Samsung S3C24xx and
 S3C64xx architectures multiplatform.  The multiplatform did not happen
 yet here - just cleaning up and merging into one arch/arm/mach-s3c
 directory.  However this is step forward for multiplatform or at least
 to keep this code still maintainable.
 
 This pulls also branch with changes for Samsung SoC sound drivers from
 broonie/sound because the cleanups there were part of this series and
 all further patches depend on them.

Arnd Bergmann 673085f450 ARM: s3c24xx: move iis pinctrl config into boards
The s3c_gpio_cfgall_range() function is an internal interface of the
samsung gpio driver and should not be called directly by drivers, so
move the iis pin initialization into the boards.

This means the pin configuration is only run once at early boot, rather
than each time the driver binds, but the effect should be the same.

Note that the s3c2412-i2s driver has no boards using it in mainline linux,
the driver gets selected for the jive machine but is never instantiated.
