I think it might be best if you add your own compatible to the list in
the gpio-pca95xx binding just in case there are some behavioural quirks
of your CPLD implementation? Not sure if this should be
"facebook,pca9506" or "wywinn,pca9506", but assuming facebook, from
there you can specify

    compatible = "facebook,pca9506", "nxp,pca9506";

This allows you to add the quirks to the driver as required in the
future through the more-specific compatible.
