OK, so leave current SuperH code the way it is, but add the case for (pdev->dev.of_node != NULL) and do things the 'new way' so I can have an RTC clock name of "rtc". Question: Is your idea to add all the clocks (X1, X3, EXTAL), but put the first one as the peripheral clock (the one that runs the register interface 'p0')? Chris
