From ff09b41f0398d67db9614c29f1b67ae82a19d68d Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Thu, 11 Feb 2016 16:56:30 -0800 Subject: [PATCH] drm/fsl-dcu: use clk helpers Use clk_prepare_enable and clk_disable_unprepare helpers. This also fixes a sequence issue in the enable path which lead to a warning on resume.
