From e1f8c729fa890c67bb4532f22c22ace6fb0e1aaf Mon Sep 17 00:00:00 2001 From: Dmitry Eremin-Solenikov Date: Fri, 25 Feb 2011 12:13:38 +0100 Subject: pxa2xx_pic: update to use qdev Use qdev/sysbus framework to handle pxa2xx-pic. Instead of exposing IRQs via array, reference them via qdev_get_gpio_in(). Patch has been modified by the committer.
