If anyone has any objections, please let me know. ------------------ From: Mike Leach [ Upstream commit eeedc5421dd3b51de73e6106405c5c77f920f281 ] Corrected to get the port numbering to allow programmable replicator driver to operate correctly. By convention, CoreSight devices number ports, not endpoints in the .dts files:- port { reg endpoint { } } Existing code read endpoint number - always 0x0, rather than the correct port number.
