For the following devicetree, view 'nested' as being on the bus.
Previously, only 'node' was considered to be on the bus.
some-bus {
compatible = "foo,bus-controller";
node {
nested {
compatible = "foo,device-on-bus";
};
};
};
In practice, this means that a 'bus:' key in the binding for
'foo,bus-controller' will now get matched up to an 'on-bus:' key in the
binding for 'foo,device-on-bus'.
Change the meaning of Node.bus and add two new attributes Node.on_bus
and Node.bus_node, with these meanings:
Node.bus:
The bus type (as a string) if the node is a bus controller, and
None otherwise
Node.on_bus:
The bus type (as a string) if the node appears on a bus, and None
otherwise. The bus type is determined from the closest parent
that's a bus controller.
Node.bus_node:
The node for the bus controller if the node appears on a bus, and
None otherwise
It's a bit redundant to have both Node.bus_node and Node.on_bus, since
Node.on_bus is the same as Node.bus_node.bus, but Node.on_bus is pretty
handy to save some None checks.
Also update gen_defines.py to use Node.on_bus and Node.bus_node instead
of Node.parent wherever the code deals with buses.
