From: Jesse Barnes Date: Fri, 2 Sep 2011 19:54:37 +0000 (-0700) Subject: drm/i915: support 3 pipes on IVB+ X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=27f8227b1e2b326a9a0995dd9c1f14893c61ee01;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git drm/i915: support 3 pipes on IVB+ Well almost anyway. IVB has 3 planes, pipes, transcoders, and FDI interfaces, but only 2 pipe PLLs. So two of the pipes must use the same pipe timings (e.g. 2 DP plus one other, or two HDMI with the same mode and one other, etc.).
