The values were determined experimentally via boot tests, not by measuring the bus behaviour with a scope. We plan to do scope measurements to confirm or refine the values and will update the devicetree if necessary once these have been obtained. However, with the patch we can write and read data without issue, where as booting the system without the patch failed at the point of mounting the rootfs.
