The GW16082 mini-PCI expansion mezzanine uses a TI XIO2001 PCIe-to-PCI bridge with legacy INTA/B/C/D interrupts. These interrupts are assigned in the reverse order according to the PCI spec.
If the TI bridge is found on the Ventana PCI bus, add device-tree nodes according to bus enumeration explicitly defining the interrupt mapping to override the default PCI mapping in the Linux kernel. This allows the GW16082 to work with upstream kernels that support device-tree irq parsing.
