RE: [PATCH v3] ASoC: rt1320: Add RT1320 SDCA vendor-specific driver

...

+static const struct sdw_device_id rt1320_id[] = {

• SDW_SLAVE_ENTRY_EXT(0x025d, 0x1320, 0x3, 0x0, 0),
  

• SDW_SLAVE_ENTRY_EXT(0x025d, 0x1320, 0x3, 0x1, 0),
  

• {},
  

Sorry, not following why one of the two entries in the table is an SDCA class device and the other not - both rely on SDCA controls/entities/functions/etc. That doesn't really align with the notion that VA and VB only differ by their DSP capabilities, so not sure what the 0/1 difference means.

VA/VB will use class id 0 because of the hardware issue. VC will fix this and use the class id 1.
