From 253b0887b3736160feac9ccdcf146a2073e41463 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 13 May 2009 17:38:11 +0900 Subject: sh: clkfwk: Rework legacy CPG clock handling. This moves out the old legacy CPG clocks to their own file, and converts over the existing users. With these clocks going away and each CPU dealing with them on their own, CPUs can gradually move over to the new interface.
