Or patch description.  It's neither
generic (IP-block-specific) nor simple.

It's not simple; I've seen far simpler GPIO
controllers.

Just rename it to match the IP block used.
That removes all confusion.  Engineers will
 be able to know more easily whether this
driver is even relevant to them.

An example might be "amba-9999 (a made-up
number, likely not matching a GPIO controller).
DesignWare drivers tend to use dw_* prefixes.
