Commit ae602456 ("ASoC: samsung: drop support for legacy
S3C24XX DMA API") removed the old code for the samsung specific
DMA interfaces, now that everybody can use dmaengine.

This picks up the few remaining pieces left over by that patch:

The most important one is the removal of the dma_data->ops->started()
calls in ac97. My understanding is that these are only required
for drivers that do not support cyclic transfers, which the new dma
engine driver now does, so we can simply remove them. This would also
fix at least one bug in the ac97 driver on newer machines, which
currently gives us a NULL pointer dereference from trying to call
dma_data->ops->started().

Further, we must no longer 'select' S3C2410_DMA, which conflicts
with the dmaengine driver. The SND_S3C_DMA symbol is now
useless, because it is always selected, so we can remove it
and build the dmaengine support unconditionally.

Finally, we should not 'select' S3C24XX_DMAC or S3C64XX_PL080,
which may have additional dependencies. This replaces it with
'depends on', to be more conservative.

Both codecs used by snow, max98090 and max98095 require the use

The commit [e1d4d3c8: ASoC: free jack GPIOs before the sound card is

This is the same change as commit fb6b8e71 "ASoC: tegra: free jack
GPIOs before the sound card is freed", but applied to all other ASoC
machine drivers where code inspection indicates the same problem exists.

That commit's description is:
==========
snd_soc_jack_add_gpios() schedules a work queue item to poll the GPIO to
generate an initial jack status report. If sound card initialization
fails, that work item needs to be cancelled, so it doesn't run after the
card has been freed. Specifically, freeing the card calls
snd_jack_dev_free() which calls snd_jack_dev_disconnect() which sets
jack->input_dev = NULL, and input_dev is used by snd_jack_report(), which
is called from the work queue item.

snd_soc_jack_free_gpios() cancels the work item. The Tegra ASoC machine
drivers do call this function in the platform driver remove() callback.
However, this happens after the sound card is freed, at least when the
card is freed due to errors late during snd_soc_instantiate_card(). This
leaves a window where the work item can execute after the card is freed.
In next-20140522, sound card initialization does fail for unrelated
reasons, and hits the problem described above.

To solve this, fix the Tegra ASoC machine drivers to clean up the Jack
GPIOs during the snd_soc_card's .remove() callback, which is executed
before the overall card object is freed. also, guard the cleanup call
based on whether we actually setup up the GPIOs in the first place.
Ideally, we'd do the cleanup in a struct snd_soc_dai_link .fini/remove
function to match where the GPIOs get set up. However, there is no such
callback.
==========

Note that I have not even compile-tested this in most cases, since most
of the drivers rely on specific mach-* support I don't have enabled, and
don't support COMPILE_TEST. Testing by the relevant board maintainers
would be useful.

The baudclock may be used and set by different streams.

Allow only the first stream to set the bitclock rate. Other streams have
to try to get to the correct rate without modifying the bitclock rate
using the SSI internal clock modifiers.

The variable baudclk_streams is introduced to keep track of the active
streams that are using the baudclock. This way we know if the baudclock
may be set and whether we may enable/disable the clock.

baudclock enable/disable is moved to hw_params()/hw_free(). This way we can
keep track of the baudclock in those two functions and avoid a running
clock while it is not used. As hw_params()/hw_free() may be called
multiple times for the same stream, we have to use baudclk_streams
variable to know whether we may enable/disable the clock.
