It does not. I am now thinking to drop this patch altogether, and continue to
use MXC as defined in bindings, irrespective of connection to hardware as MX or
MXC. For ex SM8550/SA8775P have MXC, while QCS8300 have MX, but again, as you
mentioned, these difference just alters some property in DT, binding can remain
same.
