Hi Rob,

Do we need to add this if it's just a soc-specific compatible
we add in the device tree to future proof things in case we
discover quirks later on?

AFAIK we haven't been doing this, and this is likely to create
some confusion, because they aren't actually mentioned anywhere
in the driver.
