(no changes since v4)
Changes in v4:
- Remove unevaluatedProperties from regulators schema reference
Changes in v3:
- Require the regulators node to have a unit address
- Reference the regulator schema from the SRAM controller schema
- Move the system LDOs example to the SRAM controller schema
- Reorder the patches so the example passes validation
Changes in v2:
- New patch for v2
