That's good news. I'm probably the customer that's been nagging the 
Marvell support team. But I'm also impatient hence I started working on 
this series. The pinctrl and mvneta changes have already been accepted.

Personally I thought they'd be rejected upstream as being too vague and 
generic. I settled on armada-98dx2530 as I saw the 98dx2530 name used on 
the Marvell Portal to refer to the CnM block for the AC5/AC5X. I was 
going to call the board file "rd-ac5x-32g16hvg6hlg.dts" as that's what 
the silkscreen on the board I have says but I shortened it to "rd-ac5x" 
as the switch port configuration is largely irrelevant to the board 
support I'm trying to get landed.

I'm not against changing if there is a consensus. On another thread the 
idea of armada-98dx25xx/armada-98dx35xx was mentioned. That might be a 
reasonable compromise (although technically there's no difference in the 
CPU block between the 25xx and 35xx).

The x is from AC5X so we'd actually have armada-98dx25xx-db.dts and 
armada-98dx35xx-db.dts. My board would be called armada-98dx35xx-rd.dts 
or perhaps armada-98dx3550-rd.dts.
