Add adi,adg2404 to the compatible list. The ADG2404 is a 4:1 analog
multiplexer that benefits from the enable GPIO support to prevent
glitches during channel transitions.

Why do you need the compatible? I do not understand this patchset. You
are saying you integrate it into gpio-mux, but what you did is to
duplicate the compatible and binding.

Half of your patches are not necessary, you only needed to add
enable-gpios to gpio-mux with argument that ADG2404 can use such binding
(in complete/full/proper way).

Best regards,

... and Rob at v2 asked already that...
