Move code from system sleep pm to runtime pm callbacks to ensure proper driver state preservation when device is under power domain.

Turns out commit a0562819 ("drm/i915: Get panel_type from OpRegion panel details") has regressed quite a few machines. So it looks like we can't use the panel type from OpRegion on all systems, and yet we absolutely must use it on some specific systems. Despite trying, I was unable to find any automagic way to determine if the OpRegion panel type is respectable or not. The only glimmer of hope I had was bit 8 in the SCIC response, but that turned out to not work either (it was always 0 on both types of systems). So, to fix the regressions without breaking the machine we know to need the OpRegion panel type, let's just add a quirk for this. Only specific machines known to require the OpRegion panel type will therefore use it. Everyone else will fall bck to the VBT panel type. The only known machine so far is a "Conrac GmbH IX45GM2". The PCI subsystem ID on this machine is just a generic 8086:2a42, so of no use. Instead we'll go with a DMI match. I suspect we can now also revert commit aeddda06 ("drm/i915: Ignore panel type from OpRegion on SKL") but let's leave that to a separate patch. v2: Do the DMI match in the opregion code directly, as dev_priv->quirks gets populated too late Cc: Rob Kramer <rob@solution-space.com> Cc: Martin van Es <martin@mrvanes.com> Cc: Andrea Arcangeli <aarcange@redhat.com> Cc: Dave Airlie <airlied@linux.ie> Cc: Marco Krüger <krgsch@gmail.com> Cc: Sean Greenslade <sean@seangreenslade.com> Cc: Trudy Tective <bertslany@gmail.com> Cc: Robin Müller <rm1990@gmx.de> Cc: Alexander Kobel <a-kobel@a-kobel.de> Cc: Alexey Shumitsky <alexey.shumitsky@gmail.com> Cc: Emil Andersen Lauridsen <mine809@gmail.com> Cc: oceans112@gmail.com Cc: James Hogan <james@albanarts.com> Cc: James Bottomley <James.Bottomley@HansenPartnership.com> Cc: stable@vger.kernel.org References: https://lists.freedesktop.org/archives/intel-gfx/2016-August/105545.html References: https://lists.freedesktop.org/archives/dri-devel/2016-August/116888.html References: https://lists.freedesktop.org/archives/intel-gfx/2016-June/098826.html Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=94825 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97060 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97443 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97363 Fixes: a0562819 ("drm/i915: Get panel_type from OpRegion panel details") Tested-by: Marco Krüger <krgsch@gmail.com> Tested-by: Alexey Shumitsky <alexey.shumitsky@gmail.com> Tested-by: Sean Greenslade <sean@seangreenslade.com> Tested-by: Emil Andersen Lauridsen <mine809@gmail.com> Tested-by: Robin Müller <rm1990@gmx.de> Tested-by: oceans112@gmail.com Tested-by: Rob Kramer <rob@solution-space.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1473758539-21565-1-git-send-email-ville.syrjala@linux.intel.com References: http://patchwork.freedesktop.org/patch/msgid/1473602239-15855-1-git-send-email-adrienverge@gmail.comAcked-by: Jani Nikula <jani.nikula@intel.com> (cherry picked from commit c8ebfad7) Signed-off-by: Jani Nikula <jani.nikula@intel.com>

This reverts commit 1c80c25f Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed May 18 18:47:12 2016 +0200 drm/i915/psr: Make idle_frames sensible again There are panels that needs 4 idle frames before entering PSR, but VBT is unproperly set. Also lately it was identified that idle frame count calculated at HW can be off by 1, what makes the minimum of 2, at least. Without the current vbt+1 we are with the risk of having HW calculating 0 idle frames and entering PSR when it shouldn't. Regardless the lack of link training.

Even if PR3 support is available on the bridge, it will not be used if the PCI layer considers it unavailable (i.e. on all laptops from 2013 and 2014). Ensure that this condition is checked to allow a fallback to the Optimus DSM for device poweroff. Initially I wanted to call pci_d3cold_enable before checking bridge_d3 (in case the user changed d3cold_allowed), but that is such an unlikely case and likely fragile anyway.

Due to assigning the 'replaced' value instead of or'ing it, if drm_atomic_crtc_set_property() gets called multiple times, the last call will define the color_mgmt_changed flag, so a non-updating call to a property can reset the flag and prevent actual hw state updates required by preceding property updates.

An evil userspace could try to cause deadlock by passing an unfaulted-in GEM bo as submit->bos (or submit->cmds) table. Which will trigger msm_gem_fault() while we already hold struct_mutex.
