* soundwire: intel_ace2x: add new_peripheral_assigned callbackPierre-Louis Bossart2023-05-271-0/+12
| | | | | | | | | | | | | | Add the abstraction needed to only program the LSDIID registers for the HDaudio extended links. It's perfectly fine to program this register multiple times in case devices lose sync and reattach.

* soundwire: intel_ace2x: use common helpers for bus start/stopPierre-Louis Bossart2023-05-271-0/+6
| | | | | | | | | | | | | | The sequences are so far identical, so the abstraction is a bit over-engineered. In time we will simplify if there is no need to special case or work-around programming sequences.

* soundwire: intel_ace2x: add DAI registrationPierre-Louis Bossart2023-05-271-0/+161
| | | | | | | | | | | | | | | | | | The code is similar to the previous implementation, the only difference is that the PDI descriptors are now in different areas. Using common helpers proves tricky with multiple changed registers, workarounds that are no longer necessary. It's simpler to duplicate the intel_register_dai() function rather than try to add multiple levels of abstraction and indirections.

* soundwire: intel_ace2x: configure link PHYPierre-Louis Bossart2023-05-271-0/+19
| | | | | | | | | | | | | | | | | Unlike previous hardware generations, the glue-to-master transition is not managed by software, instead the transitions are managed as part of the power-up/down sequences controlled by SPA/CPA bits. The only thing that's required is to configure the link PHY for 'normal' operation instead of the PHY test mode.

* soundwire: intel_ace2x: set SYNCPRD before powering-upPierre-Louis Bossart2023-05-271-2/+40
| | | | | | | | | | | | | | | | | | | The registers used for multi-link synchronization are no longer in the SHIM but in the HDaudio multi-link capability space. Use helpers to configure the SYNCPRD value, and wait for SYNCPU to change after powering-up. Note that the SYNCPRD value is shared between all sublinks, for obvious reasons if those links are supposed to be synchronized. The value of SYNCPRD is programmed only once for all sublinks.

The register map and programming sequences for the ACE2.x IP are completely different and need to be abstracted with a different set of callbacks. This initial patch adds a new file, follow-up patches will add each required callback.
