Arrow SoCKit, what interrupt vector accelerometer uses?

1,116 Views

I am trying to add support for onboard accelerometer in Linux on Arrow SoCKit board (it uses 5CSXFC6DF31 FPGA chip). I have added ADXL345 chip to my device tree and enabled it in my Linux kernel configuration. It looks like it requires interrupt to be assigned to the device, but how do I know what interrupt vector it uses? It's interrupt lines are connected to UART0_RX,CAN0_RX,SPIM0_SS1,HPS_GPIO61 (pin B22 on the Cyclone chip). I've also tried to route interrupt line through FPGA but Quartus' fitter has some problems with it.
