This register appeared in Haswell. It does not have an EDP version
because the EDP transcoder is always tied to the DDIA clock. Notice
that if we call PIPE_CLK_SEL(pipe) when pipe is PIPE_A and transcoder
is TRANSCODER_EDP we might introduce a bug, that's why this is a
transcoder register even though it does not have an EDP version.
Even though Haswell names this register PIPE_CLK_SEL, it will be
renamed to TRANS_CLK_SEL in the future, so let's just start using the
real name that makes more sense and avoids misusage.

Before Haswell we used to have the CPU pipes and the PCH transcoders.
We had the same amount of pipes and transcoders, and there was a 1:1
mapping between them. After Haswell what we used to call CPU pipe was
split into CPU pipe and CPU transcoder. So now we have 3 CPU pipes (A,
B and C), 4 CPU transcoders (A, B, C and EDP) and 1 PCH transcoder
(only used for VGA).
For all the outputs except for EDP we have an 1:1 mapping on the CPU
pipes and CPU transcoders, so if you're using CPU pipe A you have to
use CPU transcoder A. When have an eDP output you have to use
transcoder EDP and you can attach this CPU transcoder to any of the 3
CPU pipes. When using VGA you need to select a pair of matching CPU
pipes/transcoders (A/A, B/B, C/C) and you also need to enable/use the
PCH transcoder.
For now we're just creating the cpu_transcoder definitions and setting
cpu_transcoder to TRANSCODER_EDP on DDI eDP code, but none of the
registers was ported to use transcoder instead of pipe. The goal is to
keep the code backwards-compatible since on all cases except when
using eDP we must have pipe == cpu_transcoder.
V2: Comment the haswell_crtc_off chunk, suggested by Damien Lespiau
and Daniel Vetter.
We currently need the haswell_crtc_off chunk because TRANSCODER_EDP
can be used by any CRTC, so when you stop using it you have to stop
saying you're using it, otherwise you may have at some point 2 CRTCs
claiming they're using TRANSCODER_EDP (a disabled CRTC and an enabled
one), then the HW state readout code will get completely confused.
In other words:
Imagine the following case:
xrandr --output eDP1 --auto --crtc 0
xrandr --output eDP1 --off
xrandr --output eDP1 --auto --crtc 2
After the last command you could get a "pipe A assertion failure
(expected off, current on)" because CRTC 0 still claims it's using
TRANSCODER_EDP, so the HW state readout function will read it
(through PIPECONF) and expect it to be off, when it's actually on
because it's being used by CRTC 2.
So when we make "intel_crtc->cpu_transcoder = intel_crtc->pipe" we
make sure we're pointing to our own original CRTC which is certainly
not used by any other CRTC.

On Ironlake we have one PCH transcoder and FDI per pipe, so we know
that if ironlake_crtc_driving_pch returns false we can disable the PCH
transcoder and we also know that when we disable the crtc we can also
disable the PCH transcoder.
On Haswell there is only 1 PCH transcoder and FDI and they can be used
by any CRTC. So if for one specific crtc haswell_crtc_driving_pch
returns false we can't assert anything about the state of the PCH
transcoder or the FDI link without checking if any other CRTC is using
the PCH.
So on this commit remove the "assert_fdi_{t,r}x_disabled" form
haswell_crtc_enable and also only disable FDI and the PCH transcoder
if the port being disabled was actually a PCH port (we only have one
port using PCH: the VGA port).

I've noticed that with this patch we know get and unknown connection

But that beats the previous state of affairs, where it tried to use
pipe B, actually used pipe A and concluded that something is connected
(although it's the LVDS on pipe A and nothing on the VGA connector on
pipe B).
I've tried to make load detect work by remapping the pipe->planes
stuff, so that crtc 0 will use pipe B and hence we still have
something left for load-detect on pipe A. But alas, that upset the hw

So there's still some things to figure out, but this here will at

The overlay on the i830M has a peculiar failure mode: It works the
first time around after boot-up, but consistenly hangs the second time
it's used.
Chris Wilson has dug out a nice errata:
"1.5.12 Clock Gating Disable for Display Register
Address Offset: 06200h–06203h
"Bit 3
Ovrunit Clock Gating Disable.
0 = Clock gating controlled by unit enabling logic
1 = Disable clock gating function
DevALM Errata ALM049: Overlay Clock Gating Must be Disabled: Overlay
& L2 Cache clock gating must be disabled in order to prevent device
hangs when turning off overlay.SW must turn off Ovrunit clock gating
(6200h) and L2 Cache clock gating (C8h)."
Now I've nowhere found that 0xc8 register and hence couldn't apply the
l2 cache workaround. But I've remembered that part of the magic that
the OVERLAY_ON/OFF commands are supposed to do is to rearrange cache
allocations so that the overlay scaler has some scratch space.
And while pondering how that could explain the hang the 2nd time we
enable the overlay, I've remembered that the old ums overlay code did
_not_ issue the OVERLAY_OFF cmd.
And indeed, disabling the OFF cmd results in the overlay working
flawlessly, so I guess we can workaround the lack of the above
workaround by simply never disabling the overlay engine once it's
enabled.
Note that we have the first part of the above w/a already implemented
in i830_init_clock_gating - leave that as-is to avoid surprises.

This requires a few changes since that dpcd value is above the

above 0xf there's a big gap and nothing that looks like we should
cache it while a given device is plugged in. It's also the same value

Hence extend the various dpcd arrays in the radeon driver, use
proper symbolic constants where applicable (one place overallocated
the dpcd array to 25 bytes). Then also drop the rd_interval cache -
radeon_dp_link_train_init re-reads the dpcd block, so the values we'll

Merge tag 'v3.7-rc2' into drm-intel-next-queued
Linux 3.7-rc2
Backmerge to solve two ugly conflicts:
- uapi. We've already added new ioctl definitions for -next. Do I need to say more?
- wc support gtt ptes. We've had to revert this for snb+ for 3.7 and
also fix a few other things in the code. Now we know how to make it
work on snb+, but to avoid losing the other fixes do the backmerge
first before re-enabling wc gtt ptes on snb+.
And a few other minor things, among them git getting confused in
intel_dp.c and seemingly causing a conflict out of nothing ...

The big thing is the disabling of the hsw support by default, cc: stable.
We've aimed for basic hsw support in 3.6, but due to a few bad
happenstances we've screwed up and only 3.8 will have better modeset
support than vesa. To avoid yet another round of fallout from such a
gaffle on for the next platform we've added a module option to disable
early hw support by default. That should also give us more flexibility in
bring-up.
Otherwise just small fixes:
- 3 fixes from Egbert for sdvo corner cases
- invert-brightness quirk entry from Egbert
- revert a dp link training change, it regresses some setups
- and shut up a spurious WARN in our gem fault handler.
- regression fix for an oops on bit17 swizzling machines, introduce in 3.7
- another no-lvds quirk
* 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel:
drm/i915: Initialize obj->pages before use by i915_gem_object_do_bit17_swizzle()
drm/i915: Add no-lvds quirk for Supermicro X7SPA-H
drm/i915: Insert i915_preliminary_hw_support variable.
drm/i915: shut up spurious WARN in the gtt fault handler
Revert "drm/i915: Try harder to complete DP training pattern 1"
DRM/i915: Restore sdvo_flags after dtd->mode->dtd Roundrtrip.
DRM/i915: Don't clone SDVO LVDS with analog.
DRM/i915: Add QUIRK_INVERT_BRIGHTNESS for NCR machines.
DRM/i915: Don't delete DPLL Multiplier during DAC init.
We were programming register 0x42020 twice on those platforms. Once
should be enough.
