Setting 'additionalProperties: false' is frequently omitted, but is important in order to check that there aren't extra undocumented properties in a binding. Ideally, we'd just add this automatically and make this the default, but there's some cases where it doesn't work. For example, if a common schema is referenced, then properties in the common schema aren't part of what's considered for 'additionalProperties'. Also, sometimes there are bus specific properties such as 'spi-max-frequency' that go into bus child nodes, but aren't defined in the child node's schema. So let's stick with the json-schema defined default and add 'additionalProperties: false' where needed. This will be a continual review comment and game of wack-a-mole.

On the IXP4xx SoCs, the Network Processing Engine (NPE) is a small
|
|
processor that can load a firmware to perform offloading of networking
|
|
and crypto tasks. It also manages the MDIO bus to the ethernet PHYs
|
|
on the IXP4xx platform. All IXP4xx platforms have three NPEs at
|
|
consecutive memory locations. They are all included in the same
|
|
device node since they are not independent of each other.
