ASOC: SOF: simplify nocodec mode

2021-04-12T16:05:55Z

Replace ugly #if (!IS_ENABLED) by if (!IS_ENABLED), remove cross-module dependencies and use classic mechanism to pass information to the machine driver.

ASoC: SOF: nocodec: modify DAI link definitions

2020-11-20T16:42:14Z

The ignore_machine field in the component driver is used to ignore the FE DAI links defined in the machine driver, override BE fixups and set the stream names for the DAI links defined in the machine driver. This is required to make SOF compatible with the legacy machine drivers. In the case of the nocodec machine driver in SOF, there is no need to rely upon this ignore_machine logic in the core. Modify the machine driver to set DAI link stream names and the BE hw_params_fixup callback appropriately.

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

2019-12-09T18:39:35Z

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.
