soundwire: intel: use substream for .free callback

2023-05-27T10:36:47+00:00

The interface is not needed for IPC3 but will be needed for
ACE2.x+IPC4 combinations, with the substream information passed as a
parameter.

ASoC: SOF/soundwire: re-add substream in params_stream structure

2023-05-27T10:36:47+00:00

An earlier simplification to only pass the direction is no longer
suitable, all the ACE2.x HDaudio DMA management relies on access to
the substream structure.

This patch is an iso-functionality change, the HDaudio DMA parts will
be provided separately.

soundwire: intel_ace2x: add new_peripheral_assigned callback

2023-05-27T10:36:46+00:00

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: add eml_lock in the interface for new platforms

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

In existing Intel/SoundWire systems, all the SoundWire configuration
is 'self-contained', with the 'shim_lock' mutex used to protect access
to shared registers in multi-link configurations.

With the move of part of the SoundWire registers to the HDaudio
multi-link structure, we need a unified lock. The hda-mlink
implementation provides an 'eml_lock' that is used to protect shared
registers such as LCTL and LSYNC, we can pass it to the SoundWire
side. There is no issue with possible dangling pointers since the
SoundWire auxiliary devices are children of the PCI device, so the
'eml_lock' cannot be removed while the SoundWire side is in use.

This patch only adds the interface for now.

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_ace2x: add empty new ops for LunarLake

2023-05-27T10:36:44+00:00

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.

soundwire: intel: add ACE2.x SHIM definitions

2023-05-27T10:36:44+00:00

With the HDaudio extended link integration, the SHIM and IP registers
are split in blocks

a) SHIM generic registers
b) IP registers (same offsets for Cadence IP as before)
c) SHIM vendor-specific registers

Add offsets and definitions as defined in the hardware specifications.

soundwire: intel: add abstraction for cmdsync check

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.
