Since v3
- Move unevaluatedProperties line after $ref for binding patch.
- Add Reviewed-by tag for binding patch.
Since v2
- Remove the properties for interrupt controller things in the binding documentation.
- Fix dtc error for typo, it's 'regulator-name', not 'regulator-compatible'.
- Add regulator min/max microamp to allow otg vbus current adjustable in example.
- Specify the active-level for charge-enable-gpios in binding example.
