good news, just got a message from the support with a quote from one
of their developers:
Have the customer that needs support for the ath cards to use this
branch. https://github.com/SolidRun/linux-stable/tree/linux-4.4.y-marvell
note that the device-tree is board specific and for now they should
create a symlink from their board file to armada-388-clearfog.dtb
when i look at the change,
https://github.com/SolidRun/linux-stable/commit/e12aa24ca56ca773b5c59a3cc2915b4e82e6be18
this looks exactly like the problem we had :)
I will try this today.
Regards
Oli
