From 5f45bc50976ee1f408f7171af155aec646655a37 Mon Sep 17 00:00:00 2001 From: Sonic Zhang Date: Fri, 15 Jun 2007 17:45:49 +0800 Subject: [PATCH] Add irq_flags to struct pata_platform_info On some embedded platforms, such as blackfin, the gpio interrupt for IDE interface is designed to be triggered with high voltage. The gpio port should be configured properly by set_irq_type() when register the irq. This patch enable the generic pata platform driver to accept platform irq flags data.
