Backmerge because:
- Maarten needs latest atomic patches from drm-misc.
- Lionel needs the color manager core patch from drm-misc.
- Ander extracted intel_dpll_mgr.c, we need a backmerge to avoid git
losing track of things too often (right now it seems ok due to
cherry-picks).
- Tvrtko needs a stable baseline to apply some large-scale renaming
patches to i915 GEM code.

The recent commit [0bdf5a05647a: drm/i915: Add reverse mapping between
port and intel_encoder] introduced a reverse mapping to retrieve
intel_dig_port object from the port number. The code assumed that the
port vs intel_dig_port are 1:1 mapping. But in reality, this was a
too naive assumption.
As Martin reported about the missing HDMI audio on his SNB machine,
pre-HSW chips may have multiple intel_dig_port objects corresponding
to the same port. Since we assign the mapping statically at the init
time and the multiple objects override the map, it may not match with
the actually enabled output.
This patch tries to address the regression above. The reverse mapping
is provided basically only for the audio callbacks, so now we set /
clear the mapping dynamically at enabling and disabling HDMI/DP audio,
so that we can always track the latest and correct object
corresponding to the given port.

Now that the mess with AUX clock divder rounding is sorted out and
we have both cdclk and rawclk cached in dev_priv, we can clean up
the .get_aux_clock_divider() functions a bit.
The main thing here is just calling ilk_get_aux_clock_divider()
from hsw_get_aux_clock_divider() except for the LPT:H special
case.
We could go further and call g4x_get_aux_clock_divider() from
ilk_get_aux_clock_divider() for the PCH ports, but I'm sure Jani
would object, so leave that be.
While at it repeat the comment where the AUX clock comes from

Generalize rawclk handling by storing it in dev_priv.
Presumably our hrawclk readout works at least for CTG and ELK
since we've been using it for DP AUX on those platforms. There
are no real docs anymore after configdb vanished, so the only
reference is the public CTG GMCH spec. What bits are listed in
that doc match our code. The ELK GMCH spec have no relevant
details unfortunately.
The PNV situation is less clear. Starting from
commit aa17cdb4f836 ("drm/i915: initialize backlight max from VBT")
we assume that the CTG/ELK hrawclk readout works for PNV as well.
At least the results *seem* reasonable for one PNV machine (Lenovo
Ideapad S10-3t). Sadly the PNV GMCH spec doesn't have the goods on
the relevant register either.
So let's keep assuming it works for PNV,ELK,CTG and read it out on
those platforms. G33 also has hrawclk according to some notes
in BSpec, but we don't actually need it for anything, so let's not
even try to read it out there.

Currently we check if the encoder's idea of dotclock agrees with what
we calculated based on the FDI parameters. We do this in the encoder
.get_config() hooks, which isn't so nice in case the BIOS (or some other
outside party) made a mess of the state and we're just trying to take
over.
So as a prep step to being able sanitize such a bogus state, move the
the sanity check to just after we've read out the entire state. If
we then need to sanitize a bad state, it should be easier to move the
sanity check to occur after sanitation instead of before it.

Looks like g4x hpd live status bits actually agree with the spec. At
least they do on the machine I have, and apparently on Nick Bowler's
g4x as well.
So gm45 may be the only platform where they don't agree. At least
that seems to be the case based on the (somewhat incomplete)
logs/dumps in [1], and Daniel has also tested this on his gm45
sometime in the past.
So let's change the bits to match the spec on g4x. That actually makes
the g4x bits identical to vlv/chv so we can just share the code
between those platforms, leaving gm45 as the special case.

So far, the i915 driver and some other drivers set it to the drm_device,
which doesn't allow one to know which DP a given aux channel is related
to. Changing this to be the drm_connector provides proper nesting, still
allowing one to get the drm_device from it. Some drivers already set it
to the drm_connector.
This also removes the need to add a sysfs link for the i2c device under
the connector, as it will already be there.
v9:
- As a side effect, drm_dp_aux_unregister() must be called before
intel_connector_unregister(), as both the aux.dev and the i2c adapter
dev are children of the drm_connector device now. Calling
drm_dp_aux_unregister() before prevents them from being destroyed
twice.
v10:
- move aux_fini() to connector_unregister(), instead of moving
drm_dp_aux_unregister() outside of connector_register().

When we stop the sink CRC calculation we wait a while until the counter
is reset to zero and return -ETIMEDOUT. However the sink crc was
calculated already by this point so we just ignore this return at
the main function.
So, let's also ignore the message and put it as a debug message instead
of an error one. The message might still be useful when debuging
test failures so we could be able to know something was not going so
well with sink crc stop.

Here are the patchset to add get_eld op to audio component for
communicating more directly between i915 and HD-audio.
Currently, the HDMI/DP audio status and ELD are notified and obtained
via the hardware-level communication over HD-audio unsolicited event
and verbs although the graphics driver holds the exactly same
information. As we already have a notification via audio component,
this is another step forward; namely, the audio driver may fetch
directly the audio status and ELD via the new component op.
The commits are based on Dave's latest drm-next branch.

Mainly aux communications on sink_crc
were failing a lot randomly on recent platforms.
The first solution was to try to use intel_dp_dpcd_read_wake, but then
it was suggested to move retries to drm level.
Since drm level was already taking care of retries and didn't want
to through random retries on that level the second solution was to
put the retries at aux_transfer layer what was nacked.
So I realized we had so many retries in different places and
started to organize that a bit. During this organization I noticed
that we weren't handing at all the case were the message size was
zeroed. And this was exactly the case that was affecting sink_crc.
Also we weren't respect BSPec who says this size message = 0 or > 20
are forbidden.
It is a fact that we still have no clue why we are getting this
forbidden value there. But anyway we need to handle that for now
so we return -EBUSY and drm level takes care of the retries that
are already in place.
v2: Print debug messsage when this case is reached as suggested
by Jani.
v3: This patch is crucial to make PSR test cases reliably working
on SKL. So split this patch from the aux re-org series and add
a FIXME as a promisse to continue that effort besides reminding
to remove the sleep when that is merged.
v4: Use a bigger usleep range so kernel doesn't need to be interrupted
on a exact time, as suggested by Paulo.
But anyway we should discuss the better time
ranges on the EBUSY handle re-org at drm level since this one here
is temporary.

This patch adds a reverse mapping from a digital port number to
intel_encoder object containing the corresponding intel_digital_port.
It simplifies the query of the encoder a lot.
Note that, even if it's a valid digital port, the dig_port_map[] might
point still to NULL -- usually it implies a DP MST port. Due to this
fact, the NULL check in each place has no WARN_ON() and just skips the
port. Once when the situation changes in future, we might introduce
WARN_ON() for a more strict check.

The cherryview device shares many characteristics with the valleyview
device. When support was added to the driver for cherryview, the
corresponding device info structure included .is_valleyview = 1.
This is not correct and leads to some confusion.
This patch changes .is_valleyview to .is_cherryview in the cherryview
device info structure and simplifies the IS_CHERRYVIEW macro.
Then where appropriate, instances of IS_VALLEYVIEW are replaced with
IS_VALLEYVIEW || IS_CHERRYVIEW or equivalent.
v2: Use IS_VALLEYVIEW || IS_CHERRYVIEW instead of defining a new macro.
Also add followup patches to fix issues discovered during the first
review. (Ville)
v3: Fix some style issues and one gen check. Remove CRT related changes
as CRT is not supported on CHV. (Imre, Ville)
v4: Make a few more optimizations. (Ville)

Back merge tag 'v4.4-rc4' into drm-next
We've picked up a few conflicts and it would be nice
to resolve them before we move onwards.
Introduce intel_display_port_aux_power_domain() which simply returns
the appropriate AUX power domain for a specific port, and then replace
the intel_display_port_power_domain() with calls to the new function
in the DP code. As long as we're not actually enabling the port we don't
need the lane power domains, and those are handled now purely from
modeset_update_crtc_power_domains().
My initial motivation for this was to see if I could keep the DPIO power
wells powered down while doing AUX on CHV, but turns out I can't so this
doesn't change anything for CHV at least. But I think it's still a
worthwile change.
v2: Add case for PORT E. Default to POWER_DOMAIN_AUX_D for now. (Ville)

Currently we round the AUX clock divider down on g4x, to closest
on HSW/BDW port A, and up everywhere else. We are supposed to get
as close to 2MHz as we can, so round to closest seems like the
best option.

Currently a DDI port may register the DP hotplug handler even though
it's used with HDMI, and the DP HPD handler overrides the encoder
type forcibly to DP. This caused the inconsistency on a machine
connected with a HDMI monitor; upon a hotplug event, the DDI port is
suddenly switched to be handled as a DP although the same monitor is
kept connected, and this leads to the erroneous blank output.
This patch papers over the bug by excluding the previous HDMI encoder
type from this override. This should be fixed more fundamentally,
e.g. by moving the encoder type reset from the HPD or by having
individual encoder objects for HDMI and DP. But since the bug has
been present for a long time (3.17), it's better to have a
quick-n-dirty fix for now, and keep working on a cleaner fix.

We sometimes get a spurious CPU pipe underrun somewhere between
enabling port A and enabling vdd for the panel. Observed on both
ILK and IVB with port A eDP. Suppress FIFO underrun reporting
around the port and vdd enable to avoid the dmesg errors.
Not sure if port D eDP would suffer from the same issue, but assume
that it doesn't until proven differently.

Make I915_READ and I915_WRITE more type safe by wrapping the register
offset in a struct. This should eliminate most of the fumbles we've had
with misplaced parens.
This only takes care of normal mmio registers. We could extend the idea
to other register types and define each with its own struct. That way
you wouldn't be able to accidentally pass the wrong thing to a specific
register access function.
The gpio_reg setup is probably the ugliest thing left. But I figure I'd
just leave it for now, and wait for some divine inspiration to strike
before making it nice.
As for the generated code, it's actually a bit better sometimes. Eg.
looking at i915_irq_handler(), we can see the following change:
lea 0x70024(%rdx,%rax,1),%r9d
mov $0x1,%edx
- movslq %r9d,%r9
- mov %r9,%rsi
- mov %r9,-0x58(%rbp)
- callq *0xd8(%rbx)
+ mov %r9d,%esi
+ mov %r9d,-0x48(%rbp)
callq *0xd8(%rbx)
So previously gcc thought the register offset might be signed and
decided to sign extend it, just in case. The rest appears to be
mostly just minor shuffling of instructions.
v2: i915_mmio_reg_{offset,equal,valid}() helpers added
s/_REG/_MMIO/ in the register defines
mo more switch statements left to worry about
ring_emit stuff got sorted in a prep patch
cmd parser, lrc context and w/a batch buildup also in prep patch
vgpu stuff cleaned up and moved to a prep patch

It was created at 'commit aabc95dcf20 (drm/i915: Dont -ETIMEDOUT
on identical new and previous (count, crc).")' becase the counter
wasn't reliable.
Now that we properly wait for the counter to be reset we can rely
a bit more in the counter.
Also that patch stopped to return -ETIMEDOUT so the test case is
unable to skip when it is unreliable and end up in many fails
that should be skip instead.
So, with the counter more reliable we can remove
this hack that just makes things more confusing when test cases
are really expecting the same CRC and let test case skip if that's
not the case.
