dt-bindings: reset: Drop the hisilicon,hi6220-reset binding 



The hisilicon,hi6220-sysctrl, hisilicon,hi6220-mediactrl, and
hisilicon,hi6220-aoctrl controllers are already described in:

  Documentation/devicetree/bindings/arm/hisilicon/controller/sysctrl.yaml
  Documentation/devicetree/bindings/arm/hisilicon/controller/hi6220-domain-ctrl.yaml

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>;

                ...

        };
