What's a frame here, and does it overlap with any of the existing delay configuration we have? In general it's better for this stuff to be configured at runtime by the device rather than at DT time by the controller since that way if the device needs the delays we always do them if we can and if they are only needed some of the time (eg, for only one device on the bus or for only some operations) then we don't take the performance hit when we don't need to.
