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.

 Oli
