  Gigadevice Reset and Clock Unit (RCU) if a multi-function peripheral in
  charge of reset control (RCTL) and clock control (CCTL) for all SoC
  peripherals. This binding represents the reset controller (RCTL).

  To specify the reset line in a peripheral, the standard resets property needs
  to be used, e.g.:

    gpioa: gpio@xxx {
        ...
        /* cell encodes RCU register offset and control bit position */
        resets = <&rctl GD32_RESET_GPIOA>;
        ...
    }

  Predefined RCU reset cells are available in
  include/zephyr/dts-bindings/reset/gd32{xxx}.h header files, where {xxx}
  corresponds to the SoC series, e.g. f4xx.

compatible: "gd,gd32-rctl"
