delete mode 100644 Documentation/devicetree/bindings/regulator/mt6397-regulator.txt
Changes for v2:
- Remove unnecessary regulator-compatibles.
- Drop the top node of the parent device.
Since the parent device is still in txt format,
we are not moving this example to the parent device schema.
- Use 4 spaces for indentation in the example.
- Replace the old name in the example with the generic name "mt6397_regulators: regulators".
