dt-bindings: nvmem: Add bindings for rmem driver

2021-02-04T16:04:18+00:00

Firmware/co-processors might use reserved memory areas in order to pass
data stemming from an nvmem device otherwise non accessible to Linux.
For example an EEPROM memory only physically accessible to firmware, or
data only accessible early at boot time.

Introduce the dt-bindings to nvmem's rmem.

dt-bindings: Explicitly allow additional properties in common schemas

2020-10-07T16:30:06+00:00

In order to add meta-schema checks for additional/unevaluatedProperties
being present, all schema need to make this explicit. As common/shared
schema are included by other schemas, they should always allow for
additionalProperties.

dt-bindings: Add missing 'unevaluatedProperties'

2020-10-07T16:26:41+00:00

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.

dt-bindings: Whitespace clean-ups in schema files

2020-08-14T14:55:58+00:00

Clean-up incorrect indentation, extra spaces, long lines, and missing
EOF newline in schema files. Most of the clean-ups are for list
indentation which should always be 2 spaces more than the preceding
keyword.

Found with yamllint (which I plan to integrate into the checks).
