1 Hisilicon System Reset Controller
2 ======================================
3
4 Please also refer to reset.txt in this directory for common reset
5 controller binding usage.

7 The reset controller registers are part of the system-ctl block on
8 hi6220 SoC.
9
10 Required 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 - reg: should be register base and length as documented in the
15 datasheet
16 - #reset-cells: 1, see below
17
18 Example:
19 sys_ctrl: sys_ctrl@f7030000 {
20 compatible = "hisilicon,hi6220-sysctrl", "syscon";
21 reg = <0x0 0xf7030000 0x0 0x2000>;
22 #clock-cells = <1>;
23 #reset-cells = <1>;
24 };
25
26 Specifying reset lines connected to IP modules
27 ==============================================
28 example:
29
30 uart1: serial@..... {
31 ...
32 resets = <&sys_ctrl PERIPH_RSTEN3_UART1>;
33 ...
34 };
