Ok, I had a close look at it today. This will simply not work in 3.18, the at91sam9261ek was fully supported using a board file and partially supported using a device tree. The USB gadget driver will not work using device tree on 3.18. There are multiple solutions: - Stop trying to boot kernels before v4.0 using DT on at91sam9 boards - Add a quick fix to ioremap the matrix when using DT. - Backport 20 or so patches to v3.18 I would personally go for the first solution as there is probably not much interest in v3.18 on that board. -- Alexandre Belloni, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
