From d16caf69ce26dbd2ec3ae4e0072c2a60f1896c89 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Mon, 23 Mar 2009 10:07:48 +0100 Subject: [PATCH] i.MX35 clock support: remove automotive path It is no longer present in newer cores. Unfortunately Freescale decided to put the bit which decides between automotive clock path and consumer clock path in the automotive clock path direction. With current code we cannot detect the core revision, so just remove automotive path completely.
