Subject: [PATCH 2/4] drm/i915: Use adjusted mode clk for calculating DSI clk
Date: Wed, 16 Sep 2015 14:48:39 +0530	[thread overview]
Message-ID: <1442395121-19251-3-git-send-email-gaurav.k.singh@intel.com> (raw)
In-Reply-To: <1442395121-19251-1-git-send-email-gaurav.k.singh@intel.com>

Earlier, pclk was getting used for calculating DSI clk. For single link
MIPI panels, it will work fine. But for dual link MIPI, since pclk gets
halved, DSI clk will have a wrong value.
