description: |
  This binding describes the ARC AXS10x boards custom IP-block which allows
  to control reset signals of selected peripherals. For example DW GMAC, etc...
  This block is controlled via memory-mapped register (AKA CREG) which
  represents up-to 32 reset lines.
  As of today only the following lines are used:
   - DW GMAC - line 5

properties:
  compatible:
    const: snps,axs10x-reset

  reg:
    maxItems: 1

  '#reset-cells':
    const: 1

required:
  - compatible
  - reg
  - '#reset-cells'

additionalProperties: false

examples:
  - |
    reset: reset-controller@11220 {
        compatible = "snps,axs10x-reset";
        #reset-cells = <1>;
        reg = <0x11220 0x4>;
    };

    // Specifying reset lines connected to IP modules:
    ethernet {
        resets = <&reset 5>;
    };
