-Eckelmann SIOX GPIO bus
-
-Required properties:
-- compatible : "eckelmann,siox-gpio"
-- din-gpios, dout-gpios, dclk-gpios, dld-gpios: references gpios for the
-    corresponding bus signals.
-
-Examples:
-
-        siox {
-                compatible = "eckelmann,siox-gpio";
-                pinctrl-names = "default";

-                dout-gpios = <&gpio6 8 0>;
