Subject[PATCH v2 2/7] dt-bindings: net: dsa: mediatek,mt7530: fix reset lines
Date
- Fix description of mediatek,mcm. mediatek,mcm is not used on MT7623NI.
- Add description for reset-gpios.
- Invalidate reset-gpios if mediatek,mcm is used.
- Invalidate mediatek,mcm if the compatible device is mediatek,mt7531.
- Require mediatek,mcm for the described MT7621 SoCs as the compatible
string is only used for MT7530 which is a part of the multi-chip module.
