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.

soundwire: cadence: use dai_runtime_array instead of dma_data

2022-11-09T04:29:46+00:00

Simplify the code with a Cadence-specific dai_runtime_array, indexed
with dai->id, instead of abusing dma_data.

soundwire: cadence: rename sdw_cdns_dai_dma_data as sdw_cdns_dai_runtime

2022-11-09T04:29:46+00:00

The existing 'struct sdw_cdns_dma_data' has really nothing to do with
DMAs. The information is stored in the dai->dma_data, but this is
really private data that should be stored in a different context.

Beyond the academic elegance discussion, using dma_data is a problem
for new Intel hardware where the dma_data structure is already used
for true DMA handling performed by other parts of the code.

This patch prepares a transition away from the use of dma_data, for
now with a rename-only change.
