As of now we edit the DTS (disable RC node and enable EP mode) but now we have to delete RC node and add EP node and build DTBS which looks like quite a work.

Or even better, the modes should have been switchable without modifying DTB at all. Since it was chosen to put hardware configuration in DT, you'll have to live with the problems that causes. My point it the same, examples of how to do something do not belong in the DT files. Put the example nodes in the documentation somewhere, then you can copy paste from that.

Examples should go in the bindings or other documentation. Remove this node.
