< 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>
#     generation: <define | structure>
