Hisilicon System Reset Controller
Please also refer to reset.txt in this directory for common reset
controller binding usage.
The reset controller registers are part of the system-ctl block on
hi6220 SoC.
Required properties:
- compatible: should be one of the following:
- "hisilicon,hi6220-sysctrl", "syscon" : For peripheral reset controller.
- "hisilicon,hi6220-mediactrl", "syscon" : For media reset controller.
- "hisilicon,hi6220-aoctrl", "syscon" : For ao reset controller.
- reg: should be register base and length as documented in the
- #reset-cells: 1, see below
sys_ctrl: sys_ctrl@f7030000 {
compatible = "hisilicon,hi6220-sysctrl", "syscon";
reg = <0x0 0xf7030000 0x0 0x2000>;
#clock-cells = <1>;
#reset-cells = <1>;
Specifying reset lines connected to IP modules
uart1: serial@..... {
resets = <&sys_ctrl PERIPH_RSTEN3_UART1>;
The index could be found in <dt-bindings/reset/hisi,hi6220-resets.h>.
