| inherits: |
| - !include other.yaml # or [other1.yaml, other2.yaml] |
| # other.yaml contains bindings that also apply to this node. |
| # In case there are duplicate definitions in the different |
| # bindings the one that is defined first prevails. |

| < parent | child >: |
| # parent/child is used to document implicit relation between nodes. |
| # This information is required to generate parent related bits in child |
| # attributes. |
| # In case parent has 'bus', slave inherits some information from master. |
| # parent and child should share same bus-type value. |
| bus: <bus-type> |
| |
| # properties will be the contents of the device tree node |
| # property names must match the property names in the DT |
| |
| properties: |
| |
| # A typical property entry will look like the following |
| # <name of property as it is in device tree> |
| # category: <required | optional> |
| # type: <string | int | array> |
| # description: <description of property> |
