From 8be5f1a68f2c14082939dd54e7037dcee2eb54f8 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Tue, 12 May 2009 19:53:55 +0900 Subject: sh: Kill off the remnants of the old timer code. Now with all of the TMU users moved over to the new TMU driver, and the old TMU driver killed off, the left-over infrastructure can go along with it.
