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.

Bindings for the ambient light sensor veml6030 from Vishay
|
|
Semiconductors over an i2c interface.
|
|
|
|
Irrespective of whether interrupt is used or not, application
|
|
can get the ALS and White channel reading from IIO raw interface.
|
|
|
|
If the interrupts are used, application will receive an IIO event
|
|
whenever configured threshold is crossed.
|
|
|
