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"
