From f6fb7af4768bc1ddc2349f6eaefedd746c8e4913 Mon Sep 17 00:00:00 2001 From: eric miao Date: Tue, 4 Mar 2008 13:53:05 +0800 Subject: [ARM] pxa: integrate low IRQ chip (ICIP) and high IRQ chip (ICIP2) into one This makes the code better organized and simplified a bit. The change will lose a bit of performance when performing IRQ ack/mask/unmask,but that's not too much after checking the result binary. This patch also removes the ugly #ifdef CONFIG_PXA27x .. #endif by carefully not to access those pxa{27x,3xx} specific registers, this is done by keeping an internal IRQ number variable. The pxa-regs.h is also modified so registers for IRQ > PXA_IRQ(31) are made public even if CONFIG_PXA{27x,3xx} isn't defined (for pxa25x's sake) The incorrect assumption in the original code that internal irq starts from 0 is also corrected by comparing with PXA_IRQ(0). "struct sys_device" for the IRQ are reduced into one single device on pxa{27x,3xx}.
