Hi Thor,
Did you saw my patch? I think the default configuration for the timer interrupt should be <1 13 0xf01>
Otherwise, the driver get the error "GIC: PPI13 is secure or misconfigured"
Base on the ARM documentation it is a edge sensitive trigger:
http://infocenter.arm.com/help/topic/com.arm.doc.ddi0407f/CCHEIGIC.html
Or do I understand something wrong?
Best regards,
Silvan

This looks correct. In fact, our socfpga.dtsi base file uses the rising
edge.
