During detect() we would probe the connection bits to determine if there was a TV attached, and what video input type (Component, S-Video, Composite, etc) to use. However, we promptly discarded this vital bit of information and never propagated it to where it was used to determine the correct modes and setup the control registers. Fix it!

drm/i915: Sanitize the output registers after resume 2011-05-02T16:19:37+00:00 Chris Wilson chris@chris-wilson.co.uk 2011-04-12T17:06:51+00:00 72846ac3462c7d2bebc25c9a4d3e8f5739c5fb66 commit f6e5b1603b8bb7131b6778d0d4e2e5dda120a379 upstream. Similar to booting, we need to inspect the state left by the BIOS and remove any conflicting bits before we take over. The example reported by Seth Forshee is very similar to the bug we encountered with the state left by grub2, that the crtc pipe<->planning mapping was reversed from our expectations and so we failed to turn off the outputs when booting or, in this case, resuming. This may be in fact the same bug, but triggered at resume time. This patch rearranges the code we already have to clear up the conflicting state upon init and calls it from reset (which is called after we have lost control of the hardware, i.e. along both the boot and resume paths) instead.
