soundwire: intel_init: resume all devices on exit.

2024-04-11T17:22:51+00:00

When the manager becomes pm_runtime active in the remove procedure, peripherals will become attached, and do the initialization process. We have to wait until all the devices are fully resumed before the cleanup, otherwise there is a possible race condition where asynchronous workqueues initiate transfers on the bus that cannot complete. This will ensure there are no SoundWire registers accessed after the bus is powered-down.

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.
