From 9e73d6982314a903beebb2e47e585a9804f237cf Mon Sep 17 00:00:00 2001 From: Chao Xie Date: Mon, 27 Aug 2012 10:54:01 +0800 Subject: [PATCH] arm: mmp: move pxa910 clock definition to separated file move pxa910 clock definition to another file. Then pxa910 can choose common clock framework or private clock framework.
