ASoC: SOF: Intel: hda-mlink: program SoundWire LSDIID registers
Each SoundWire peripheral can be programmed from the manager side
either with a regular command FIFO, or with the HDaudio CORB/RIRB
DMA-based mechanism. The mapping between SoundWire peripheral and SDI
address is handled with the LSDIID register.
This mapping only works of course if each peripheral has a unique
address across all links. This has already been enforced in previous
Intel contributions allowing for an IDA-based solution for the device
number allocation.
The checks on the dev_num are handled at the SoundWire level, but the
locking is handled at the hda-mlink level.
