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 eMMC PHY on Intel's Lightning Mountain SoC, syscon
|
|
node is used to reference the base address of eMMC phy registers.
|
|
|
|
The eMMC PHY node should be the child of a syscon node with the
|
|
required property:
|
|
|
|
- compatible: Should be one of the following:
|
|
"intel,lgm-syscon", "syscon"
|
|
- reg:
|
|
maxItems: 1
|
|
|
|
properties:
|
|
compatible:
|
|
const: intel,lgm-emmc-phy
|
|
|
|
"#phy-cells":
|
|
const: 0
|
|
|
|
reg:
|
|
maxItems: 1
|
|
|
|
clocks:
|
|
maxItems: 1
|
|
|
|
required:
|
|
- "#phy-cells"
|
|
- compatible
|
|
- reg
|
|
- clocks
|
|
|
|
additionalProperties: false

examples:
|

|
