This is fine, just waiting for the final version of the driver.

+Synopsys GPIO via CREG (Control REGisters) driver
+
+Required properties:
+- compatible : "snps,creg-gpio-hsdk" or "snps,creg-gpio-axs10x".
+- reg : Exactly one register range with length 0x4.
+- #gpio-cells : Should be one - the pin number.
+- gpio-controller : Marks the device node as a GPIO controller.
+- ngpios : Number of GPIO pins.
+
+Example:
+
+gpio: gpio@f00014b0 {
+	compatible = "snps,creg-gpio-hsdk";
+	reg = <0xf00014b0 0x4>;
+	gpio-controller;
+	#gpio-cells = <1>;
+	ngpios = <2>;
+};
