Just as unevaluatedProperties or additionalProperties are required at the top level of schemas, they should (and will) also be required for child node schemas. That ensures only documented properties are present for any node. Add unevaluatedProperties as needed, and then add any missing properties flagged by the addition.

MT6357 is a power management system chip containing 5 buck
|
|
converters and 29 LDOs. Supported features are audio codec,
|
|
USB battery charging, fuel gauge, RTC
|
|
|
|
This is a multifunction device with the following sub modules:
|
|
- Regulator
|
|
- RTC
|
|
- Keys
|
|
|
|
It is interfaced to host controller using SPI interface by a proprietary hardware
|
|
called PMIC wrapper or pwrap. This MFD is a child device of pwrap.
|
|
See the following for pwrap node definitions:
