From eced5a7eb4750e16dd571a9bd4980c68d2276f11 Mon Sep 17 00:00:00 2001 From: Wenyou Yang Date: Wed, 3 Feb 2016 10:16:49 +0800 Subject: ARM: cpu: at91: clean up peripheral clock code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Due to introducing the new peripheral clock handle functions, use these functions to clean up the duplicated code. Meanwhile, remove unneeded header file include, at91_pmc.h.
