From b2acc92e144336dd29e30dc5d26439355be750b6 Mon Sep 17 00:00:00 2001 From: Shiraz Hashim Date: Wed, 7 Mar 2012 17:00:51 +0530 Subject: mtd: fsmc: use ALE and CLE offsets from platform data ALE and CLE offsets can be different on different devices. Let devices pass these offsets to the fsmc driver through platform data.
