I think I understand my error.
Actually, the RTC (HW) support the "start-year" feature, then I suggest
to fix the binding like that:

allOf:
  - $ref: "rtc.yaml#"

properties:
  compatible:
    enum:
      - mediatek,mt6323-rtc
      - mediatek,mt6357-rtc
      - mediatek,mt6358-rtc
      - mediatek,mt6366-rtc
      - mediatek,mt6397-rtc

  start-year: true

additionalProperties: false

required:
  - compatible

examples:
  - |
    pmic {
        rtc {
            compatible = "mediatek,mt6397-rtc";
        };
    };
