From fe51bfb95c996733150c44d21e1c9f4b6322a326 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 12 Mar 2015 17:10:38 +0200 Subject: [PATCH] drm/i915: Add eDP intermediate frequencies for CHV MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit "P1273_DPLL_Programming Spreadsheet.xlsm" lists a boatload of frequencies for eDP. Try to use them all. For now I've decided not to add hardcoded DPLL dividers for these cases since chv_find_best_dpll() works just fine. I've not actually tested any of these since I don't have an eDP 1.4 panel.
