From 319edafef64406c971035c56bd68480e5a82b581 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Mon, 20 Oct 2008 18:15:30 +0100 Subject: [PATCH] smc911x: Add IRQ polarity configuration Platforms like ARM Ltd's RealView require the IRQ polarity bit to be set for the SMC9118 chip. This patch allows the dynamic configuration via the smc911x_platdata structure. This patch also changes the smc91x_platdata structure name to the correct smc911x_platdata in the smc911x_drv_probe() function.
