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
  datasheet
- #reset-cells: 1, see below

Example:
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
==============================================
example:

        uart1: serial@..... {
                ...
                resets = <&sys_ctrl PERIPH_RSTEN3_UART1>;
                ...
        };
