From 14c2607144c11653b27a423ead0703ffaa65d0b1 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 23 May 2013 11:09:57 +0200 Subject: clk: move the U300 fixed and fixed-factor to DT This converts the fixed and fixed-factor clocks in the U300 platform to register themselves from the device tree.
