Similar to how the ->crtc_mode_set hook should touch the hardware to
enable anything the ->crtc_off hook should disable anything in the
hardware. Otherwise runtime pm for dpms will not work.
Currently the only things left int the haswell_crtc_off hook is
disabling the ddi plls. We can't move the WRPLL enabling out yet
because the current ddi pll sharing code used by the haswell code
doesn't separately track active users and overall users. This must be
fixed by porting it to the generic shared display pll framework, which
is powerful enough.
But the SPLL source is only used by the crt encoder and so can be
moved already. We only need to make sure that the ddi port E is
already off, which hsw_fdi_disable does by calling
intel_ddi_post_disable.
With this the code reorg to shuffle hsw fdi/lpt specific code into a
new hsw-specific crt encoder type is now finally complete.

The call to intel_ddi_pll_enable in haswell_crtc_mode_set is the only
function that still touches the hardware state from the crtc mode_set
callback on hsw. Since the SPLL isn't ever shared we can easily take
it out into the hsw crt encoder functions.
Temporarily we'll loose a bit of WARN_ON coverage with this, but once
the WRPLLs are switched over that will be restored. For the SPLL
selection add a WARN in the hsw fdi link training code.

The always-on power well pixel path on haswell is routed such that it
bypasses the panel fitter when we use is. Which means the pfit CRC
source won't work in that configuration.
Add a new disallow-bypass flags to the pfit pipe config state and set
it when we want to use the pf CRC. Results in a bit of flicker, but
should get the job done. We'll also undo do it afterwards to make sure
other tests arent' negatively affected.
Totally untested due to lack of hsw laptops around here.
v2: s/disallow_bypass/force_power_well_on/ to avoid a double negative
(Damien).
v3: force_thru because roadsigns.
v4: Don't forget the power wells! Also note that until the runtime pm
for DPMS series is fully merged the simple disable/enable trick won't
work since the ->crtc_mode_set callback is still required to do nasty
things. This stuff is tricky, but I think by both fixing up
get_crtc_power_domains and the debugfs wa code we should always
grab/drop the additional power well correctly.

The digital ports from Ironlake and up have the ability to distinguish
between long and short HPD pulses. Displayport 1.1 only uses the short
form to request link retraining usually, so we haven't really needed
support for it until now.
However with DP 1.2 MST we need to handle the short irqs on their
own outside the modesetting locking the long hpd's involve. This
patch adds the framework to distinguish between short/long to the
current code base, to lay the basis for future DP 1.2 MST work.
This should mean we get better bisectability in case of regression
due to the new irq handling.

With the current code, we unconditionally touch
HSW_AUD_PIN_ELD_CP_VLD, which means we can touch it when the power
well is off, and that will trigger an "Unclaimed register" message.
Just adding the intel_crtc->config.has_audio should already avoid the
unclaimed register messsages, but since we actually need the power
well to make the Audio code work, it makes sense to also grab the
audio power domain reference, and release it when it's not needed
anymore.
I used IGT's pm_rpm to reproduce this bug, but it can probably be
reproduced on other tests that do modesets. I'm using a machine with
eDP+HDMI connected.

Including state readout and cross-checking. This allows us to get rid
of crtc->eld_vld on hsw+. It also means that fastboot will be unhappy
if the BIOS hasn't set up the audio routing like we want it too.
Wrt fastboot and external screens I see a few options:
- Don't.
- Try to fix up eld, infoframes and audio settings after the fact. But
that means some pretty extensive reworking of our code which
currently does all this while the pipe/port is still off.
I won't bother with converting SDVO over to this because the audio
support for SDVO is very lacking:
- We don't update the eld.
- We don't update the audio state on the sdvo encoder.
- We don't check whether the platform can even feed audio to the sdvo
encoder.
I've converted hdmi, dp & ddi all in one go since ddi needs both hdmi
and dp converted and so doing it step-by-step would have required a

If runtime PM is enabled and we unset all modes, we will runtime
suspend after __intel_set_mode() , then function
intel_modeset_check_state() will try to read the HW state while it is
suspended and trigger lots of WARNs because it shouldn't be reading
registers.
So on this patch we make intel_ddi_connector_get_hw_state() return
false in case the power domain is disabled, and we also make
intel_display_power_enabled() return false in case the device is
suspended. Notice that we can't just use
intel_display_power_enabled_sw() because while the driver is being
initialized the power domain refcounts are not reflecting the real
state of the hardware.
Just for reference, I have previously published an alternate patch for
this problem, called "drm/i915: get runtime PM at intel_set_mode".

Currently we allow encoders to indicate whether they can be part of a
cloned set with just one flag. That's not flexible enough to describe
the actual hardware capabilities. Instead make it a bitmask of encoder
types with which the current encoder can be cloned.
For now we set the bitmask to allow DVO+DVO and DVO+VGA, which should
match what the old boolean flag allowed. We will add some more cloning
options in the future.

While at it make the vdd_on/off functions static.

The first piece, intel_ddi_pll_select, finds a PLL and assigns it to
the CRTC, but doesn't write any register. It can also fail in case it
doesn't find a PLL.
The second piece, intel_ddi_pll_enable, uses the information stored by
intel_ddi_pll_select to actually enable the PLL by writing to its
register. This function can't fail. We also have some refcount sanity
checks here.
The idea is that one day we'll remove all the functions that touch
registers from haswell_crtc_mode_set to haswell_crtc_enable, so we'll
call intel_ddi_pll_select at haswell_crtc_mode_set and then call
intel_ddi_pll_enable at haswell_crtc_enable. Since I'm already

- We now have duplicated calls to intel_uncore_forcewake_reset in the
setup code to due 2 different patches merged into -next and 3.13.
The conflict is silen so I need the merge to be able to apply
Deepak's fixup patch.

Trivial conflict, it doesn't even show up in the merge diff.

VLV can have eDP on either port B or C, or even both. Based on the
VBT spec, intel_dpd_is_edp() should work on VLV too, assuming we
check the correct ports.
So instead of hardcoding port D, rename the function to
intel_dp_is_edp() and pass the port as a parameter, and use it
on VLV ports B and C.

Use the eDP values on platforms where port D is eDP. This doesn't
affect Haswell since it uses the same DDI buffer values for eDP and
DP.

Broadwell has different DDI buffer translations for eDP and DP, so add

A future patch addresses the suggestion from Art to check for eDP on
port D and use the eDP values there, too.

So you can use the panel fitter while the power well is disabled and
you also don't need to set the "pipe" bit.
v2: Rebased on top of Jesse's pfit refactor, which moved pfit state
into the pipe_config.
v3: Rebase on top of the latest Haswell/panel fitter rework, which
neatly resolves a FIXME we have in this patch here:

drm/i915: don't init DP or HDMI when not supported by DDI port
Since the commit above it is possible to have a DDI encoder that has
the HDMI connector but not the DP connector (in case the port doesn't
support DP). In this case, we must properly free the DP connector.
We just leak this once, so it's not a big deal.

The conflict in intel_drv.h tripped me up a bit since a patch in dinq
moves all the functions around, but another one in drm-next removes a
single function. So I'ev figured backing this into a backmerge would
be good.
i915_dma.c is just adjacent lines changed, nothing nefarious there.

There's no reason to init a DP connector if the encoder just supports
HDMI: we'll just waste hundreds and hundreds of cycles trying to do DP
AUX transactions to detect if there's something there. Same goes for a
DP connector that doesn't support HDMI, but I'm not sure these
actually exist.

We currently use the recommended values from BSpec, but the VBT
specifies the correct value to use for the hardware we have, so use
it. We also fall back to the recommended value in case we can't find
the VBT.
In addition, this code also provides some infrastructure to parse more
information about the DDI ports. There's a lot more information we
could extract and use in the future.
v2: - Move some code to init_vbt_defaults.
v3: - Rebase
- Clarify the "DVO Port" matching code
v4: - Use I915_MAX_PORTS
- Change the HAS_DDI checks
- Replace DRM_ERROR with DRM_DEBUG_KMS
