This is overkill in most cases, we already have a message thrown in
case of errors and have tracepoints enabled to check for IPC
duration. The only case where this might be useful is to check if
there is an interleaved IPC RX. Add a flag and only print those logs
if enabled.
In addition, the DMA_POSITION_UPDATE for traces brings limited
information in most cases and pollutes the logs for no good reason.

Merge series from Ranjani Sridharan <ranjani.sridharan@linux.intel.com>:
This set of patches includes changes to add the topology, control and
PCM ops for IPC4. It also includes a couple of patches to set the IPC4
BE DAI trigger ops for SSP/DMIC/HDA type DAI's.
As part of retiring the old defines used to specify DAI formats update the
hdmi_codec driver to use the modern names, including the variables in the
struct hdmi_codec_daifmt exported to the DRM drivers.
In updating this I did note that the only use of this information in DRM
drivers is to reject clock provider settings, thinking about what this
hardware is doing I rather suspect that there might not be any hardware
out there which needs the configuration so it may be worth considering
just having hdmi-codec support only clock consumer.

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
The context save functionality with IPC4 is triggered by sending a message to
the firmware about the pending power down of the primary core by the host.
In order to have this functionality implemented in a clean way we need to
introduce a new IPC level PM ops for core state management and use that instead
of open coding IPC messages here and there.
The first patch updates the ctx store/ctx_restore documentation to clarify that
they are optional.
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
This series handles the race which can result missing the first position update
after the trace is enabled.
In short: the firmware might send the position update (if we have enough
trace data generated) after the dma-trace is enabled by the TRACE_DMA_PARAMS_EXT
message. Depending on scheduling, load, preemption on Linux side we have seen
that occasionally this first position update got missed and we missed reading it
out.
A new state and more strict handling of host_offset can overcome this issue,
making the dtrace more reliable.

With the new state we can make sure we are not missing the first
host_offset update.
In case the dtrace is small, the DMA copy will be fast and depending on
the moonphase it might be done before we set the sdev->dtrace_state to
SOF_DTRACE_ENABLED.
The DMA will start the copy as soon as the host starts the DMA. Set the
dtrace to enabled before we let the DMA to run in order to avoid missing
the position update.
The new state is needed to cover architectures where the host side
snd_sof_dma_trace_trigger() is a NOP and the dtrace in the firmware is
ready as soon as the IPC message has been processed.

Use the context save callback to power down the primary core which is used
by the firmware as an indication that the DSP is going to be turned off.
The IMR boot setup is done in response to the primary core power down.

Instead of craft and send an IPC(3) message in hda_dsp_core_get(),
tgl_dsp_core_get() and tgl_dsp_core_put(), use the generic ops for handling
the IPC dependent implementation of core power on/off.
