[PATCH 4/4] drm/msm/hdmi: don't call clk_round_rate to check hdmi pclk for MDP5

From: Jilai Wang
Date: Wed Nov 26 2014 - 15:17:44 EST


clock driver can support dynamic rate settings for HDMI
pixelclock, so don't need to use clk_round_rate to check if the
clockrate for specific mode is supported therefore more display
modes can be supported.
