Ramesh Babu K V 8a251ff2fc intel_sst: rework jack implementation
This patch fixes the below issues w.r.t jack implementation

a) The current jack implementation in driver is implemented
   in intelmid.c. It has moved to vendor files for better managebility
b) Cleaned up jack reporting per upstream comments
c) Implemented jack for msic, added code to read adc and deduce jack
   type based on mic bias
d) Support detection of american headset

Vinod Koul 2784a80c97 intel_sst: parameter tuning ioctl
This patch adds new IOCTL for application interface.

Using parameter tuning IOCTL, application can fine
tune the audio firmware for it's requirement.

Vinod Koul afe9194d58 intel_sst: Save audio state across D3 on Medfield
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

Vinod Koul 62877913ba Staging: sst: add ioctls for post processing algorithm interface
This patch adds two new ioctls to intel_sst_ctrl device.
This i/f can be used by application to send algorithm parameters

[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]

Vinod Koul 79a35ad573 Staging: sst: Construct fw string name runtime
The firmware name for each platform is appended by PCI id of device.
This patch makes use of pci id to construct the string rather than
hardcode the string.

Vinod Koul 6f6ffec188 sst: Change the SST driver PCM interface

This allows SST driver to keep easy track of handles open

Dan Carpenter 4fc718a4b0 Staging: sst: add some __user anotations
This silences all the sparse warnings in intel_sst_app_interface.c.
It was just a matter of adding __user annotations, I didn't find any
real bugs here.  Quite a few of these were needed for stuff I added
earlier, sorry about that.

I removed a couple casts to (void *) that caused a warning like:
	drivers/staging/intel_sst/intel_sst_app_interface.c:606:27:
		warning: cast removes address space of expression
For example sst_drv_ctx->mailbox is already declared as
"void __iomem *mailbox" so casting it to void pointer isn't necessary
and it makes sparse complain because it removes the __user attribute.

Vinod Koul fffa1cca3d Staging: sst: Intel SST audio driver
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.
