From a8d3584a2df28827094f6338cde1303c467bc1f0 Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 3 Jan 2006 18:41:37 +0000 Subject: [ARM] Remove clk_use()/clk_unuse() It seems that clk_use() and clk_unuse() are additional complexity which isn't required anymore. Remove them from the clock framework to avoid the additional confusion which they cause, and update all ARM machine types except for OMAP.
