From d63fa0dc1a3636816260bc507e59e168e423f150 Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Tue, 20 Nov 2012 13:27:35 -0200 Subject: [PATCH] drm/i915: don't limit Haswell CRT encoder to pipe A This is a full revert of 59c859d6f2e78344945e8a8406a194156176bc4e: drm/i915: account for only one PCH receiver on Haswell Now that the PCH code is fixed to be able use the only PCH transcoder independently of the pipe and CPU transcoder, we can revert this.
