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.
