From 5303c0f46c8708fff4148ebcc491f78710356952 Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Mon, 9 Dec 2013 10:40:22 +0100 Subject: ARM: 7916/1: amba: Add clk_prepare|unprepare in runtime PM callbacks To fully gate the clock and thus potentially also save more power in runtime suspend state, extend clock handling with clk_prepare|unprepare in the runtime PM callbacks.
