I had a good conversation with Elad, Vadym and Serhiy. The plan is for them to take over this series and get it driven to completion. We've missed the merge window for 5.19 but hopefully we can get things in for 5.20. We expect to see another name change away from "armada" (the Alleycat5 CnM block doesn't really bear much resemblance to the Armada-3700 aside from the odd peripheral). There should also be some clarification around the clocking. As I expected there really are just some fixed dividers in the hardware that take the single 25MHz reference clock to supply clocks for the various peripherals. There is no gating or dynamic scaling possible so these are just represented as fixed-clock nodes. > >> >> Notes: >> The Marvell SDK has a number of new compatible strings.

It is not given they will be compatible. We'll still have the 98dx25xx suffixes so it should still be distinct from the Marvell SDK ones. Also hopefully once this lands upstream it will encourage Marvell to update their SDK to a newer kernel.
