zx::result<> Walk (Visitor & visitor)

This method does the following things -

* Does the initial walk of the tree and discovers devices/nodes.

* Calls |visitor.Visit()| for each node in the tree.

If |visitor.Visit()| returns something that's not `zx::ok()`, then this

will stop walking and return the error code.

This method can be called with the |DefaultVisitors| or with a collection

of visitors of user's choice.

Example:

DefaultVisitors

<

> visitors;

auto result = manager.Walk(visitors)

This needs to be called before |PublishDevices|.

zx::result<> PublishDevices (fdf::WireSyncClient<fuchsia_hardware_platform_bus::PlatformBus> & pbus_client, fidl::ClientEnd<fuchsia_driver_framework::CompositeNodeManager> mgr, fidl::SyncClient<fuchsia_driver_framework::Node> & fdf_node)

Publish the discovered devices.

The devices maybe added as a platform device using |pbus_client| if it contains any platform

resources, or it maybe added as a child of the board driver using |fdf_node|, or it maybe added

as a composite of multiple devices if it references other nodes.
