+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 : Since the generic GPIO binding is used, the
+ amount of cells must be specified as 2. The first cell is the
+ pin number, the second cell is used to specify optional parameters:
+ See "gpio-specifier" in .../devicetree/bindings/gpio/gpio.txt.
+- 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 = <2>;
+ ngpios = <2>;
+};
