Nit, "n" is always the default, there is no need for this line.

You need more text here please.  Provide a better description of what
hardware is supported and the name of the module if it is built aas a
module.

Also that if you select this one, the C driver will not be built (which
is not expressed in the Kconfig language, why not?

This can be expressed in Kconfig, no need to put this here, right?
