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. Add unevaluatedProperties or additionalProperties as appropriate, and then add any missing properties flagged by the addition.

|
The ASPEED SD/SDIO/eMMC controller exposes two slots implementing the SDIO
|
|
Host Specification v2.00, with 1 or 4 bit data buses, or an 8 bit data bus if
|
|
only a single slot is enabled.
|
|
|
|
The two slots are supported by a common configuration area. As the SDHCIs for
|
|
the slots are dependent on the common configuration area, they are described
|
|
as child nodes.
