Intel has asked that this driver now be removed from the tree, and I am
happy to oblige.

This 2nd batch of implicit module.h users only appeared when we
removed the unnecessary module.h from include/linux/miscdevice.h
[The 1st batch is already present in Greg's staging tree.]

SST HW on MRST doesn't need to reload the firmware during suspend/resume
cycle, so remove the extra workload. This also fix a bug that the firmware
sample rate can't be modified when there is no active playback/capture
stream.

The irq for audio is shared, so when device is supended driver should
not the read register and ignore the interrupt.
This patch ignores interrupts when device is suspended.

The current driver remove was erroneous and causes
errors when unloading or loading second time
This patch fixes both of these issues

During suspend and runtime_suspend audio dsp will be in D3 state
and will loose its context.
This patch adds support in driver to save the dsp context
and restore this context during resume

[This will need further discussion in the context of the final ALSA interface
but is fine for staging, ie anyone who relies on it should expect changes
Also fixed a missing kmalloc fail check]

This is the Intel SST audio driver.
As compared to the previous versions it has all the printks and other stuff
noted cleaned up and more hardware support. The Aava support is disabled in
this patch (is_aava resolves to 0) because the Aava board detection logic
is not yet upstream.
The driver itself is a combination of a traditional ALSA driver and a
hardware assisted offload driver which can play audio while the processor
is asleep but which can't do all the more interactive stuff.
In the general case most software would use the ALSA interface, but the
other interface is needed for certain classes of use such as music playback
on highly power consumption sensitive devices.
This is going to staging primarily because it depends upon the staging memrar
driver.
