From 92b913b08b18faa487b0c744282fafd944446ade Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Fri, 25 Apr 2008 16:28:33 -0400 Subject: [ARM] Orion: fix ->map_irq() PCIe bus number check The current orion5x board ->map_irq() routines check whether a given bus number lives on the PCIe controller by comparing it with the PCIe controller's primary bus number. This doesn't work in case there are multiple buses in the PCIe domain, i.e. if there exists a PCIe bridge on the primary PCIe bus. This patch adds a helper function (orion5x_pci_map_irq()) that returns the IRQ number for the given PCI device if that device has a hard-wired IRQ, or -1 otherwise, and makes each board's ->map_irq() function use this helper function.
