ASoC: SOF: move arch_ops under ops

2019-12-18T20:02:02+00:00

The current structures are not well designed. We include Xtensa
information from the ACPI and PCI levels, but at the Kconfig/module
level everything Xtensa related is included at the sof/intel level.

Move the arch_ops under ops so that Xtensa is hidden in the DSP ops,
with a structure that follows the Kconfig/module partition.

ASoC: SOF: Introduce state machine for FW boot

2019-12-18T19:52:20+00:00

Add a state machine for FW boot to track the
different stages of FW boot and replace the boot_complete
field with fw_state field in struct snd_sof_dev.
This will be used to determine the actions to be performed
during system suspend.

One of the main motivations for adding this change is the
fact that errors during the top-level SOF device probe cannot
be propagated and therefore suspending the SOF device normally
during system suspend could potentially run into errors.
For example, with the current flow, if the FW boot failed
for some reason and the system suspends, the SOF device
suspend could fail because the CTX_SAVE IPC would be attempted
even though the FW never really booted successfully causing it
to time out. Another scenario that the state machine fixes
is when the runtime suspend for the SOF device fails and
the DSP is powered down nevertheless, the CTX_SAVE IPC during
system suspend would timeout because the DSP is already
powered down.

ASoC: SOF: Make creation of machine device from SOF core optional

2019-12-09T18:39:35+00:00

Currently, SOF probes machine drivers by creating a platform device
and passing the machine description as private data.

This is driven by the ACPI restrictions. Ideally, ACPI tables
should contain the description for the machine driver. This is
not possible because ACPI tables are frozen and used on multiple
OS-es (e.g Windows).

In the case of Device Tree we don't have this restriction, so we
choose to probe the machine drivers by creating a DT node as is
the standard ALSA way.

This patch makes the probing of machine drivers from SOF
core optional allowing for Device Tree platforms to decouple
the SOF core from machine driver probing.

Along with this, it also consolidates the machine driver selection
for Intel platforms by defining optional ops for selecting the machine
driver based on the ACPI match for HDA and non-HDA platforms and
setting the mach params.

ASoC: SOF: partition audio-related parts from SOF core

2019-12-09T18:38:57+00:00

Move all the audio-specific code in the core,
audio-specific logic in the top-level PM callbacks
and the core header files into a separate file
(sof-audio.*) in preparation for adding an
audio client device.

In the process of moving all structure definitions
for widget, routes, pcm's etc, the snd_sof_dev
member in all these structs is replaced with
the snd_soc_component member. Also, use the component
device instead of the snd_sof_dev device wherever
possible in the PCM component driver,
control IO functions and the topology parser as the
component device will be moved over to the client
device later on.

ASoC: SOF: core: modify the signature for snd_sof_create_page_table

2019-12-09T18:38:01+00:00

Modify the signature for snd_sof_create_page_table to
take struct device pointer as an argument instead of
struct snd_sof_dev as this will be used by both the SOF
core device and its clients. Also, move the definition
out of core.c to utils.c.
