From 3c5c6d88855baf9c3b9aa6243a37bb179f5a737e Mon Sep 17 00:00:00 2001 From: Gaurav K Singh Date: Wed, 1 Jul 2015 15:58:51 +0300 Subject: [PATCH] drm/i915: Support for higher DSI clk MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit For MIPI panels requiring higher DSI clk, values needs to be added in lfsr_converts table for getting the correct values of pll ctrl and dividor values which gets programmed in cck regs, otherwise DSI PLL does not get locked leading to no display on the MIPI panel.
