Compatible should work fine, Though I doubt clock and other indices (base address etc will scale appropriately), but we could give it a shot, but we can discuss that in the context of the dts patches. > > Of course if the timers are really different across am64, am65 and j72 > then multiple compatible properties are neeeded. > > If the timer hardware is the same, then I guess we should just pick the > earliest version, so how about using ti,am64-timer? yep - the oldest version will be ti,am654-timer ( AM65 was the first K3 device.
