Subject: [PATCH v5 4/7] dt-bindings: net: dsa: mediatek,mt7530: update examples
Update the examples on the binding.
- Add examples which include a wide variation of configurations.
- Make example comments YAML comment instead of DT binding comment.
- Add interrupt controller to the examples. Include header file for
interrupt.
- Change reset line for MT7621 examples.
- Pretty formatting for the examples.
- Change switch reg to 0.
- Change port labels to fit the example, change port 4 label to wan.
