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...

dt-bindings: Add missing 'unevaluatedProperties' This doesn't yet do anything in the tools, but make it explicit so we can check either 'unevaluatedProperties' or 'additionalProperties' is present in schemas. 'unevaluatedProperties' is appropriate when including another schema (via '$ref') and all possible properties and/or child nodes are not explicitly listed in the schema with the '$ref'. This is in preparation to add a meta-schema to check for missing 'unevaluatedProperties' or 'additionalProperties'. This has been a constant source of review issues.
