ASoC: SOF: pcm: invoke platform hw_free for STOP/SUSPEND triggers
snd_sof_pcm_platform_hw_params() will be called when the stream is
restarted with a prepare ioctl. This happens in two cases i.e. when a
suspended stream is resumed or when a stream is restarted without
intermediate call to sof_pcm_hw_free(). Make sure to call
snd_sof_pcm_platform_hw_free() in both these cases to keep it balanced.

ASoC: SOF: Intel: power optimizations with HDaudio SPIB register
Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:

	The use of the SPIB register helps reduce power consumption - though
	to a smaller degree than DMI_L1. This hardware capability is however
	incompatible with userspace-initiated rewinds typically used by
	PulseAudio.

	In the past (2015..2017) Intel suggested an API extension to let
	applications disable rewinds. At the time the feedback was that such a
	capability was too Intel-specific and SPIB remained unused except for
	loading DSP code. We now see devices with smaller batteries being
	released, and it's time to revisit Linux support for SPIB to extend
	battery life.

	In this update the rewinds are disabled via an opt-in kernel
	parameter. In the previous reviews, there was consensus that a Kconfig
	option was too complicated for distributions to set, and we are
	missing a TBD API to expose such capabilities to user-space.

	The debate on whether or not to use rewinds, and the impact of
	disabling rewinds, will likely be closed when Intel releases the
	'deep-buffer' support, currently under development [2][3]. With this
	solution, rewinds will not be needed, ever. When an application deals
	with content that is not latency-sensitive (e.g. music playback), it
	will be able to reduce power consumption by selecting a different PCM
	device with increased buffering capabilities.  Low-latency streams
	will be handled by the 'regular' path. In other words, the impossible
	compromise between power and latency will be handled with different
	PCM devices/profiles for the same endpoint, and we can push the design
	of capability negotiation to a later time when all the building blocks
	(firmware topology, kernel, userspace) are ready - we still have
	firmware xruns, DPCM race conditions to solve, and a need to describe
	these alternate PCM devices with UCM using 'modifiers'.

ASoC: SOF: sof-audio: setup sched widgets during pipeline complete step
Older firmware prior to ABI 3.19 has a dependency where the scheduler
widgets need to be setup last. Moving the call to sof_widget_setup()
before the pipeline_complete() call also helps remove the need for the
'reverse' direction when walking through the widget list - this was
only working because of the topology macros but the topology does not
require any order.

6c26b5054c
ASoC: SOF: Intel: add .ack support for HDaudio platforms
When we disable rewinds, then the .ack can be used to program SPIB
with the application pointer, which allows the HDaudio DMA to save
power by opportunistically bursting data transfers when the path to
memory is enabled (and conversely to shut it down when there are no
transfer requests).

The SPIB register can only be programmed with incremental values with
wrap-around after the DMA RUN bits are set. For simplicity, we set the
INFO_NO_REWINDS flag in the .open callback when we already need to
program the SNDRV_PCM_INFO_SYNC_APPLPTR flag.

Rewinds are not used by many applications. One notable application
using rewinds is PulseAudio. Practical experiments with
Ubuntu/PulseAudio default settings did not show any audible issues,
but the user may hear volume changes and notification with a delay,
depending on the size of the ring buffer and latency constraints.

The choice of disabling rewinds is exposed as a kernel parameter and
not a Kconfig option to avoid any undesirable side-effects.

ASoC: SOF: add support for dynamic pipelines with multi-core
This patch adds support for dynamic pipelines with multi-core
by using the platform-specific core_get/put() ops to
power up/down a core when a widget is set up/freed.

Along with this, a few redundant functions are removed:
1. sof_pipeline_core_enable() is no longer needed as the
pipeline core will be set up when the pipeline widget
is set up
2. sof_core_enable() is replaced with snd_sof_core_get()
4. core_power_up/down() DSP ops are deprecated and replaced with
core get/put ops.
5. Core power down in sof_widget_unload() during topology
removal is also removed as it is not really needed. For dynamic
pipelines, the cores will be powered off when they are not used.
For static pipelines, the cores will be powered off in the device
remove callback.

         -> load_modules()
      -> snd_sof_run_firmware (2)

    We need to implement dsp_reset callback (1) that will actually reset
    the DSP but keep it stalled.

    In order to implement this we do the following:
            -> put DSP into reset (assert CoreReset bit from PWRCTL)
            -> stall the DSP using RunStall bit from AudioDSP_REG2 mix
            -> take DSP out of reset (de-assert CoreReset bit from PWRCTL)

    At this moment the DSP is taken out of reset and Stalled! This means
    that we can load the firmware and then start the DSP (2).

    Until now we resetted the DSP by turning down the Audiomix PD. This
    doesn't work for Runtime PM if another IP is keeping Audiomix PD up.

    By introducing dsp_reset() we no longer rely on turning off the
    audiomix to reset the DSP.

ASoC: SOF: imx8m: Add runtime PM / System PM support
We make use of common imx8m_suspend / imx8m_resume functions
for both system PM and runtime PM.

imx8m_suspend:
	- frees the MU channels
	- disables the clocks

imx8m_resume
	- enables the clocks
	- requests the MU channels

On i.MX8MP there is no dedicated functionality to put the DSP in reset.
The only way of doing this is to POWER DOWN the Audiomix domain.

We are able to do this because turning off the clocks and freeing the
channels makes the Audiomix to have no users thus PM kernel core turns
it down.

SOF core will not call system PM suspend handler if the DSP is already
down, but at resume it will call the system PM resume. So, we need to
keep track of the state via snd_sof_dsp_set_power_state

Few insights on how SOF core handles the PM:
 - SOF core uses PM runtime autosuspend (with a timeout of 2 secs)
 - at probe, SOF core boots the DSP and lets the PM runtime suspend to
   turn it off, if there is no activity
 - when someone opens the ALSA sound card (aplay/arecord, etc) ALSA core
   calls PM runtime resume to turn on the DSP
 - when the ALSA sound card is closed SOF core make use of PM subsystem
  to call PM runtime suspend and thus turning off the DSP.

ASoC: SOF: imx8: Add runtime PM / System PM support
Handle clocks and mailbox channels at runtime suspend/resume
in order to save power.

DSP runtime PM uses a timeout of 2s. If device
is idle for 2s system will enter runtime suspend.

Because SOF state machine assumes that even if the DSP wasn't previously
active at a System resume, will re-load the firmware we need to make sure
that all needed resources are active.

Kernel core will take care of enabling the PD, we need to make sure that
we request the MU channels.

We need at least 3 clocks in order to power up and access
DSP core registers found on i.MX8QM, i.MX8QXP and i.MX8MP
platforms.

Add code to request these clocks and enable them at probe. Next
patches will add PM support which will only activate clocks when
DSP is used.

DSP clocks are already documented in
Documentation/devicetree/bindings/dsp/fsl,dsp.yaml

We choose to add:
	* imx8_parse_clocks
	* imx8_enable_clocks
	* imx8_disable_clocks

wrappers because in the future DSP will need to take care about the
clocks of other related Audio IPs (e.g SAI, ESAI).
