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 clock controller (CCTL).
To specify the clocks in a peripheral, the standard clocks property needs
to be used, e.g.:
gpioa: gpio@xxx {
...
/* cell encodes RCU register offset and control bit position */
clocks = <&cctl GD32_CLOCK_GPIOA>;
...
}
Predefined RCU clock cells are available in
include/zephyr/dts-bindings/clock/gd32{xxx}-clocks.h header files, where {xxx}
corresponds to the SoC series, e.g. f4xx.
