+description: |
+  MediaTek PMIC based RTC is an independent function of MediaTek PMIC that works
+  as a type of multi-function device (MFD). The RTC can be configured and set up
+  with PMIC wrapper bus which is a common resource shared with the other
+  functions found on the same PMIC.

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

As this is only a compatible string, just fold this into the MFD schema 
doc.

Actually, it probably also supports the start-year property

What about rest of rtc.yaml schema?

Best regards,
Krzysztof
