From e47bb515c57853c1f41474dae199cb033e747f66 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Wed, 12 May 2010 14:21:24 +0000 Subject: [PATCH] ARM: mach-shmobile: Use shared clock framework Teach SH-Mobile ARM how to make use of the shared SH clock framework. This commit is one atomic switch that dumps the local hackery and instead links in the shared clock framework code in drivers/sh. A few local functions are kept in clock.c.
