I think it is specific to Altera's glue logic. It selects either a clock connected directly to the ARM HPS core or a clock routed from Altera FPGA fabric. Control register is in the altera sysmgr. -- Regards Phil Reid -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
