soundwire: intel: move bank switch routine to common intel_bus_common.c

2023-03-15T13:54:02Z

No functionality change, just moving the routines to a common file so that they can be used for new hardware.

soundwire: intel: add abstraction for cmdsync check

2023-03-15T13:54:02Z

If we add one more callback, we can have common bank switch sequences between old and new hardware: the only difference is where the CMDSYNC register is located.

soundwire: intel: move bus common sequences to different file

2023-03-15T13:54:02Z

Now that the bus start/stop/clock_stop sequences use the ops, we can move them to a different file to reuse them. Note that we could in theory remove the abstraction for all those sequences and directly call the functions in intel_auxdevice.c. To allow for more flexibility and have means to special-case new platforms, we decided to keep the abstraction. If in time it becomes clear there is no benefit the abstraction will be simplified.

soundwire: intel: add sync_arm/sync_go to ops

2023-03-15T13:54:02Z

The bus start/stop sequences can be reused between platforms if we add a couple of new callbacks. In following patches the code will be moved to a shared file.

soundwire: intel: split auxdevice to different file

2022-11-23T14:41:49Z

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