soundwire: intel_init: use eml_lock parameter

2023-05-27T10:36:45+00:00

Now that the ASoC/SOF/HDAudio parts has retrieved the mutex and set the parameter, we can use it to share the same synchronization across the two domains.

ASoC/soundwire: intel: pass hdac_bus pointer for link management

2023-05-27T10:36:45+00:00

The hdac_bus pointer is used to access the extended link information and handle power management. Pass it from the SOF driver down to the auxiliary devices.

soundwire: intel/cadence: set ip_offset at run-time

2023-05-27T10:36:45+00:00

Select relevant ip-offset depending on hardware version. This offset is used to access MCP_ or IP_MCP_ registers with a fixed offset. For existing platforms, the offset is exactly zero. Starting with LunarLake, the offset is 0x4000.

soundwire: intel_init: remove check on number of links

2022-11-23T15:32:08+00:00

The number of links is checked with a chip-dependent helper in the caller, remove the check in drivers/soundwire/intel_init.c This change makes intel_init.c hardware-agnostic - which is quite fitting for a layer that only creates auxiliary devices.

soundwire: intel_init: remove useless interrupt enablement in interrupt thread

2022-11-23T15:32:01+00:00

When the code reaches the SoundWire interrupt thread handling, the interrupt was enabled already, and there is no code that disables it -> this is a no-op sequence.

soundwire: intel: split auxdevice to different file

2022-11-23T14:41:49+00:00

The auxdevice layer is completely generic, it should be split from intel.c which is only geared to the 'cnl' hw_ops now.

soundwire: intel: start using hw_ops

2022-11-23T14:41:48+00:00

Before introducing new hardware with completely different register spaces and programming sequences, we need to abstract some of the existing routines in hw_ops that will be platform-specific. For now we only use the 'cnl' ops - after the first Intel platform with SoundWire capabilities. Rather than one big intrusive patch, hw_ops are introduced in this patch so show the dependencies between drivers. Follow-up patches will introduce callbacks for debugfs, power and bus management.
