ASoC: SOF: Intel: add namespace for XTENSA

2019-12-18T20:02:21+00:00

Now that Xtensa stuff is only referenced in Intel stuff, define
namespace and import it in Intel BYT/BDW/HDaudio modules

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: Intel: add module namespace for legacy IPC

2019-12-18T19:50:53+00:00

The legacy IPC routines are only used by broadwell and baytrail
modules, import them as needed and make sure other modules cannot load
them.

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: Intel: only support INFO_BATCH for legacy platforms

2019-10-25T10:08:04+00:00

The current position update is not precise enough for PulseAudio to
work reliably with the timer-based scheduling on Baytrail,
Cherrytrail, Broadwell.

Disable the NO_PERIOD_WAKEUP capability and use BATCH to signal that
the position is only reliable and updated during period_elapsed
events.

This will be reverted when the firmware provides a more accurate
position for those platforms.

ASoC: SOF: define INFO_ flags in dsp_ops

2019-10-25T10:07:45+00:00

Currently the INFO_ flags such as PAUSE/NO_PERIOD_WAKEUP are defined
in the SOF PCM core, which doesn't scale. To account for platform
variations, these flags need to be set in DSP ops.

This patch only moves the definitions and does not change any
functionality.
