From c22f974104ec7a0d53600ffcd97ead799a96864a Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Wed, 8 Oct 2014 10:29:30 +0000 Subject: [PATCH] cns3xxx: fix shared PCI interrupt mapping This patch originally failed to combine INTA/B/C/D onto a single ARM CPU interrupt. Instead, it mapped INTA/B/C and excluded D. This patch corrects the issue by mapping all four interrupts to the single ARM CPU interrupt. The original intent of the patch still holds as the newer PCB take advantage of isolated interrupts. This fix only applies to older PCB's that do not route INTA/B/C/D to unique external ARM CPU interrupts.
