Is eCSPI hardware identical between i.MX processors?

Is the eCSPI hardware within the i.MX8 identical to previous i.MX7/6 processors?
If the hardware is the same, are the software drivers also therefore identical for each processor?


The reason I ask is that I'd like to characterise the performance of the eCSPI interface on an i.MX8M, but presently only have an i.MX7D development board available. If I can make use of the eCSPI hardware/software on the i.MX7D and be confident that it's representative of the i.MX8M eCSPI then that'd save us some time.
