1Hisilicon System Reset Controller 2====================================== 3 4Please also refer to reset.txt in this directory for common reset 5controller binding usage. 6 7The reset controller registers are part of the system-ctl block on 8hi6220 SoC. 9 10Required properties: 11- compatible: should be one of the following: 12 - "hisilicon,hi6220-sysctrl", "syscon" : For peripheral reset controller. 13 - "hisilicon,hi6220-mediactrl", "syscon" : For media reset controller. 14 - "hisilicon,hi6220-aoctrl", "syscon" : For ao reset controller. 15- reg: should be register base and length as documented in the 16 datasheet 17- #reset-cells: 1, see below 18 19Example: 20sys_ctrl: sys_ctrl@f7030000 { 21 compatible = "hisilicon,hi6220-sysctrl", "syscon"; 22 reg = <0x0 0xf7030000 0x0 0x2000>; 23 #clock-cells = <1>; 24 #reset-cells = <1>; 25}; 26 27Specifying reset lines connected to IP modules 28============================================== 29example: 30 31 uart1: serial@..... { 32 ... 33 resets = <&sys_ctrl PERIPH_RSTEN3_UART1>; 34 ... 35 }; 36 37The index could be found in <dt-bindings/reset/hisi,hi6220-resets.h>. 38
