From eae08eb2b53ffb87f3342e45ab422d8625659fcd Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Tue, 29 May 2012 05:54:39 +0000 Subject: [PATCH] mx53loco: Fix revision of Dialog boards Original code was assuming that the fuse revision version for all mx53loco boards based on Dialog PMIC was the same, which is not the case. Force the revision of all Dialog-based boards to 0. This fixes a kernel crash when PMIC is accessed in the 2.6.35 kernel for Dialog rev E boards.
