Please keep it consistent. The only existing case with ahb has it at after axi_m and others. Why making things everytime differently? I also to propose to finally drop the obvious comments, like "AHB clock". It cannot be anything else. AXI Master / slave are descriptive, so should stay. Best regards, Krzysztof
