From 191ef4fdad92c498f125537e98c11df7fe47368e Mon Sep 17 00:00:00 2001 From: Murali Karicheri Date: Tue, 23 Oct 2012 01:18:40 +0200 Subject: [PATCH] base: power - use clk_prepare_enable and clk_prepare_disable When PM runtime is enabled in DaVinci and the machine migrates to common clk framework, the clk_enable() gets called without clk_prepare(). This patch is to fix this issue so that PM run time can inter work with common clk framework. Signed-off-by: Murali Karicheri Signed-off-by: Rafael J.
