0d68210400 ASoC: Intel: Skylake: Fix to use the actual size for TLV control
DSP expects the actual length of parameters that is set through
TLV to be passed in large config set, so pass the actual size
received in tlv_control_set() instead of max size.

0ce8428ba9 ASoC: Fixes for v4.6
This is a fairly large collection of fixes but almost all driver
 specific ones, especially to the new Intel drivers which have had a lot
 of recent development.  The one core fix is a change to the debugfs code
 to avoid crashes in some relatively unusual configurations.

4f329d9fba ASoC: Intel: Skylake: Fix DSP resource de-allocation
In PRE PMD of widget handler DSP resources are allocated after
the creation of DSP pipe and modules and in POST PMD DSP
resources are destroyed.

If there is any failure in pipe or module creation in PRE PMD,
pcm trigger fails and finally POST PMD gets called and DSP
resources are freed, without getting allocated.

Fixes the DSP resource de-allocation by allocating the resource
before creation of pipe and module in PRE PMD and in POST PMD,
free the resources.

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.

9939a9c331 ASoC: Intel: Skylake: Add helper routines to handle module params
Some DSP modules have user configurable parameters. These
parameters are required by modules in the following scenario
	-  during initialization
	-  after initialization using set parameter

This patch adds helper routine to set module parameters using
large config set IPC message and removes params to be passed as
init module routine.

98256f83d2 ASoC: Intel: Skylake: Fix to update bit depth for module params
Module hw param fixup will change the valid bit depth based
on the fixup flag. If valid bit depth changes, need to set
the bit depth according to valid bit depth. This patch
fixes this issue of updating bit depth correctly.

7ae3cb1559 ASoC: Intel: Skylake: Fix resource cleanup on teardown
MCPS free was being done from PGA context which will free up MCPS
for only last modules in a pipe and not the rest causing MCPS
leak and eventual audio loss due to no "free" MCPS.

This needs to be freed for every module while cleaning up the
modules, so move the check to
skl_tplg_mixer_dapm_post_pmd_event()

While rigourous testing of SKL drivers, we noticed underuns and
overuns and on debug realized that we need to change driver
handling of FE pipe startup and shutdown

We need to start DMA and then run pipe together and not split
these up. Similarly while stopping we should stop pipe and then
DMA in a sequence.

8724ff1752 ASoC: Intel: Skylake: Add support for virtual dsp widgets
In SKL topology routes, some paths can be connected by a widget
which are not a DSP FW widget and virtual with respect to
firmware. In these case when module has to bind, then the
virtual DSP modules needs to skipped till a actual DSP module is
found which connects the pipelines.

So we need to walk the graph and find a widget which is real in
nature. This patch adds that support and splits
skl_tplg_pga_dapm_pre_pmu_event() fn with parsing code to
skl_tplg_bind_sinks() fn and call that recursively as well as
while parsing

The patch moves code a bit while splitting so diffstat doesn't
tell real picture

For supporting multiple dynamic pins, module state check is
incorrect. In case of unbind, module state need to be changed to
uninit if all pins in the module is is unbind state.
To handle module state correctly add pin state and use pin
state check to set module state correctly.
