5  Gigadevice Reset and Clock Unit (RCU) if a multi-function peripheral in
6  charge of reset control (RCTL) and clock control (CCTL) for all SoC
7  peripherals. This binding represents the reset controller (RCTL).
8
9  To specify the reset line in a peripheral, the standard resets property needs
10  to be used, e.g.:
11
12    gpioa: gpio@xxx {
13        ...
14        /* cell encodes RCU register offset and control bit position */
15        resets = <&rctl GD32_RESET_GPIOA>;
16        ...
17    }
18
19  Predefined RCU reset cells are available in
20  include/zephyr/dts-bindings/reset/gd32{xxx}.h header files, where {xxx}
21  corresponds to the SoC series, e.g. f4xx.
