From a6d377b6969235a3b5a6e87bdcef387d0976b41c Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Fri, 17 Apr 2009 20:11:44 +0900 Subject: sh: pci: Consolidate SH7780 PCIC IRQ routing. Now that the platform code is a bit leaner, we can start consolidating the various IRQ routing implementations. There are effectively only 2 variants, and the others can use those directly.
