From ba854e18413d2d827f050984edeb8286c3335895 Mon Sep 17 00:00:00 2001 From: Andrew Victor Date: Wed, 5 Jul 2006 17:22:52 +0100 Subject: [ARM] 3711/1: AT91 timer update Patch from Andrew Victor The AIC interrupt controller is the same on the Atmel AT91RM9200, AT91SAM9261 and AT91SAM9260 processors. This patch removes any RM9200-specific naming from the IRQ driver, and moves the AT91RM9200's default IRQ priority table into at91rm9200.c.
