SubjectRe: [PATCH 5/5] dt-bindings: pinctrl: dw: move sps,dwapb-gpio.txt to pinctrl

Indeed, I could do that if you think that's a better option. Andy however suggested to always register a pinctrl controller.
Both options suits me. Let me know what option you want me to implement.

Thanks,

Clément
