so it is actually required if you have a single Slave device? Or is it
only required when you have more than 1 device of the same type?

This is mandatory for any slave device!

If it's mandatory the wording is a bit unclear. How about something
like:

Should be ('Instance ID') from the SoundWire Enumeration
Address. This must always be provided, if multiple devices
with the same type or class or attached to the bus each
instance must have a distinct value.

That helps to make it clear.

Also the section of properties starts with Mandatory property, it should
be made Mandatory Properties instead, like in other binding docs to make
it clear that properties mentioned in the section are mandatory

Will update as suggested!
