From: Eugeni Dodonov Date: Wed, 9 May 2012 18:37:29 +0000 (-0300) Subject: drm/i915: add WR PLL programming table X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=12a13a3389716009db8deb64094656f946e8950d;p=linux-beck.git drm/i915: add WR PLL programming table This table is used for programming WR PLL clocks, used by HDMI and DVI outputs. I split it into a separate patch to simplify the HDMI enabling patch which was getting huge. Note that this table is a temporary solution for WR PLL programming. It will be reworked into a more exact algorithm at a later stage. But for now, it provides the most accurate clock setting solution, so we use it here.
