PetaLinux 2013.10 - Device Tree Generator does not connect interrupt lines for 7 series PCIe blocks

Description

I have connected the interrupt_out pin on the 7 series PCIe block to the Zynq PS7 interrupt lines in my IPI block diagram, but the PetaLinux device tree generator does not connect set the "interrupts" and "interrupt-parent" parameters in the PCIe peripherals' DTS node.

Solution

This is a known issue in PetaLinux 2013.10.

As a work-around, manually declare the "interrupts" and "interrupt-parent" parameters in the DTS file located in the <PETALINUX_PROJECT>\subsystems\linux\hw-description\system.dts file.
