In FPGA Development boards with GPIOs we use the opencores gpio verilog
rtl. This is compatible with the gpio-mmio. Add the compatible string
to allow as below.
Example:
gpio0: gpio@91000000 {
compatible = "opencores,gpio", "brcm,bcm6345-gpio";
reg = <0x91000000 0x1>, <0x91000001 0x1>;
reg-names = "dat", "dirout";
gpio-controller;
#gpio-cells = <2>;
status = "okay";
};

What you have done below does not permit this, it only permits
opencores,gpio in isolation.
