From 0e0d9dfeea38b20f54d5e056ea8b4d7e1adb2745 Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Thu, 9 Jun 2016 17:11:08 +0530 Subject: [PATCH] drm/msm/mdp5: Don't get source of MDP core clock The driver expects DT to provide the parent to MDP core clock. The only operation done to the parent clock is to set a rate. This can be achieved by setting the rate on the core clock itsef. Don't try to get the parent clock anymore.
