38c079e230 ASoC: Intel: Skylake: Remove autosuspend delay
The driver used autosuspend delay to delay going to D3. But per
HW recommendation we should go to D3 soon, so remove the delay
from driver

de1fedf25b ASoC: Intel: Skylake: Add missing PRE/POST_PMU handlers for vmixer
Some modules may be directly connected to a pipeline without a
mixer module. For these modules, we require PRE_PMU and POST_PMU
handler which will do bind between the pipelines, so add these
missing handlers.

6bd4cf8556 ASoC: Intel: Skylake: Fix bind of source with multiple sinks
skl_tplg_bind_sinks() takes only the first sink widget. This
breaks in case we have multiple sinks for a module.

So pass source widget to skl_tplg_bind_sinks() and bind for all
sinks by calling this recursively

9946f70906 ASoC: Intel: Skylake: Fix not to stop sink pipe in pga pmd event
We should not stop the sink pipe in it's pmd handler for a mixin
module as this module may still be connected to other pipes.

This will be stopped and freed by current implementation on last
connected pipe unbind.

0c684c4825 ASoC: Intel: Skylake: Fix the module state check condition
For binding modules we should check if source or destination
module is in UNINT state. We canot bind even if one of them is
in this state.

So update the check from logical AND to logical OR and do not
bind modules for this case

9cf3049e21 ASoC: Intel: Skylake: Fix return of skl_get_queue_index
In unbind modules, the skl_get_queue_index() can return error
if the pin is dynamic and module is not bound yet. So instead
of returning error this check should return success as modules
is not yet bound. This will let the module be bound when connected
pipes are enabled and will bind this as well.

So change the return value to 0

9ba8ffef96 ASoC: Intel: Skylake: Fix pipe memory allocation leak
We check and allocate pipeline resources in one shot. That causes
leaks if module creation fails later as that is not freed.

So split the resource allocation into two, first check if
resources are available and then add the resources upon
successful creation. So two new functions are added for checking
and current functions are re-purposed to only add the resources
for memory and MCPS.

While cleaning resources on module pmd event, we check for return
of skl_unbind_modules(). On failure this causes leak as all modules
attached do not have resources freed.

So ignore return value of module unbind and continue freeing
resources. This makes dapm state and resources correct.

Coincidentally, both the pointer and the structure have the same size of
8 bytes on a 64 bit machine, which "masks" the issue. Compiling for 32
bit reveals the issue more clearly.

Fix the typo for correctness, and to make the code robust to future

d93f8e550f ASoC: Intel: Skylake: add DSP platform widget event handlers
The Skylake driver topology model tries to model the firmware
rule for pipeline and module creation.
The creation rule is:
 - Create Pipe
 - Add modules to Pipe
 - Connect the modules (bind)
 - Start the pipes

Similarly destroy rule is:
 - Stop the pipe
 - Disconnect it (unbind)
 - Delete the pipe

In driver we use Mixer, as there will always be ONE mixer in a
pipeline to model a pipe. The modules in pipe are modelled as PGA
widgets.  The DAPM sequencing rules (mixer and then PGA) are used
to create the sequence DSP expects as depicted above, and then
widget handlers for PMU and PMD events help in that.

This patch adds widget event handlers for PRE/POST PMU and
PRE/POST PMD event for mixer and pga modules.  These event
handlers invoke pipeline creation, destroy, module creation,
module bind, unbind and pipeline bind unbind

Event handler sequencing is implement to target the DSP FW
sequence expectations to enable path from source to sink pipe for
Playback/Capture.

0505700104 ASoC: Intel: Add support for decoupled mode in skl driver
Decoupled mode is where audio link is broken to frontend HDA and backend
(hda/i2s/dmic/hdmi) links. This patch adds support for decoupled mode and
then adds dais, dai ops for be/fe cpu dais and interrupt handler change to
support decoupled mode
