Uh.. no. The gpio specifier has a format that's gpio controller specific, but it must include the actual pin number, although exactly how it's encoded might vary. So, you use gpios = <&controller pin1-specifier &controller pin8-specifier &controller pin9-specifier &controller pin11-specifier &controller pin15-specifier &controller pin30-specifier>; -- David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you.
