The coresight drivers relied on default bindings for graph in DT, while reusing the "reg" field of the "ports" to indicate the actual hardware port number for the connections. This can cause duplicate ports with same addresses, but different direction. However, with the rules getting stricter for the address mismatch with the label, it is no longer possible to use the port address field for the hardware port number. This patch introduces new DT binding rules for coresight components, based on the same generic DT graph bindings, but avoiding the address duplication. - All output ports must be specified under a child node with name "out-ports". - All input ports must be specified under a childe node with name "in-ports". - Port address should match the hardware port number. The support for legacy bindings is retained, with a warning.
