All nodes need an explicit additionalProperties or unevaluatedProperties unless a $ref has one that's false. Fixing this for STM32 Factory-programmed data binding needs referencing fixed layout schema for children. Add reference to the NVMEM deprecated cells for the schema to be complete.

This represents STM32 Factory-programmed read only non-volatile area: locked
|
|
flash, OTP, read-only HW regs... This contains various information such as:
|
|
analog calibration data for temperature sensor (e.g. TS_CAL1, TS_CAL2),
|
|
internal vref (VREFIN_CAL), unique device ID...

This property explicits a factory programmed area that both secure
