This adds DP 1.2 MST support on Haswell systems. Notes: a) this reworks irq handling for DP MST ports, so that we can avoid the mode config locking in the current hpd handlers, as we need to process up/down msgs at a better time. Changes since v0.1: use PORT_PCH_HOTPLUG to detect short vs long pulses add a workqueue to deal with digital events as they can get blocked on the main workqueue beyong mode_config mutex fix a bunch of modeset checker warnings acks irqs in the driver cleanup the MST encoders Changes since v0.2: check irq status again in work handler move around bring up and tear down to fix DPMS on/off use path properties. Changes since v0.3: updates for mst apis more state checker fixes irq handling improvements fbcon handling support improved reference counting of link - fixes redocking. Changes since v0.4: handle gpu reset hpd reinit without oopsing check link status on HPD irqs fix suspend/resume Changes since v0.5: use proper functions to get max link/lane counts fix another checker backtrace - due to connectors disappearing. set output type in more places fro, unknown->displayport don't talk to devices if no HPD asserted check mst on short irqs only check link status properly rebase onto prepping irq changes. drop unsued force_act Changes since v0.6: cleanup unused struct entry.

Not enough brown paper bags, you'll have to share one. (oops below). The initial match condition code was racy (locking is coming I hear). then along came: cd234b0b drm/i915: Do not dereference NULL crtc or fb until after checking Chris made an attempt to fix it, Ben "reviewed" it. Daniel merged it. Then drm/i915: Make use of intel_fb_obj() (v2) 2ff8fde1 made it worse by removing the obj check later. All in all, my laptop can't barely turn off the display without hitting this. Posted to #intel-gfx out of niceness, but I've merged this already into drm-next. Here's an oops.

Matt Roper authored
drm_plane_init() (the legacy plane initialization function) takes a bool as its final parameter; originally this indicated whether a plane was 'private' to the driver (before the DRM core understood non-overlay planes), now it indicates whether the plane is a primary plane (private planes were used by some drivers to represent primary planes internally). The newer drm_universal_plane_init() take an 'enum drm_plane_type' as its final parameter to allow the caller to specify the specific plane type desired (primary, cursor, or overlay). Due to a rebasing mistake, the primary plane helper is currently passing DRM_PLANE_TYPE_PRIMARY (enum value = 1) for drm_plane_init()'s boolean 'is_primary' parameter. This winds up giving the correct behavior since DRM_PLANE_TYPE_PRIMARY evaluates as true, but is confusing to anyone reading the code since we're passing an enum value (one of three possible values) for a boolean parameter. Replace the primary plane helper's call to drm_plane_init() with drm_universal_plane_init() so that the parameter and value types match up as expected. Signed-off-by:

We may reach this point while the machine is still runtime suspended, so we'll hit a WARN. The other encoders also don't touch registers at this point, so instead of waking the machine up, write some code to keep the register always at the same state, including after we runtime suspend/resume.
