+Subject: drm/i915: Add missing MacBook Pro models with dual channel LVDS
+
+From: Lukas Wunner <lukas@wunner.de>
+
+commit 3916e3fd81021fb795bfbdb17f375b6b3685bced upstream.
+
+Single channel LVDS maxes out at 112 MHz. The 15" pre-retina models
+shipped with 1440x900 (106 MHz) by default or 1680x1050 (119 MHz)
+as a BTO option, both versions used dual channel LVDS even though
+the smaller one would have fit into a single channel.
+
+Notes:
+  Bug report showing that the MacBookPro8,2 with 1440x900 uses dual
+  channel LVDS (this lead to it being hardcoded in intel_lvds.c by
+  Daniel Vetter with commit 618563e3945b9d0864154bab3c607865b557cecc):
+    https://bugzilla.kernel.org/show_bug.cgi?id=42842
+
+  If i915.lvds_channel_mode=2 is missing even though the machine needs
+  it, every other vertical line is white and consequently, only the left
+  half of the screen is visible (verified by myself on a MacBookPro9,1).
+
+  Forum posting concerning a MacBookPro6,2 with 1440x900, author is
+  using i915.lvds_channel_mode=2 on the kernel command line, proving
+  that the machine uses dual channels:
+    https://bbs.archlinux.org/viewtopic.php?id=185770
+
+  Chi Mei N154C6-L04 with 1440x900 is a replacement panel for all
+  MacBook Pro "A1286" models, and that model number encompasses the
+  MacBookPro6,2 / 8,2 / 9,1. Page 17 of the panel's datasheet shows it's
+  driven with dual channel LVDS:
+    http://www.ebay.com/itm/-/400690878560
+    http://www.everymac.com/ultimate-mac-lookup/?search_keywords=A1286
+    http://www.taopanel.com/chimei/datasheet/N154C6-L04.pdf
+
+  Those three 15" models, MacBookPro6,2 / 8,2 / 9,1, are the only ones
+  with i915 graphics and dual channel LVDS, so that list should be
+  complete. And the 8,2 is already in intel_lvds.c.
+
+  Possible motivation to use dual channel LVDS even on the 1440x900
+  models: Reduce the number of different parts, i.e. use identical logic
+  boards and display cabling on both versions and the only differing
+  component is the panel.
