This reverts commit dfadbbdb57b3f2bb33e14f129a43047c6f0caefa.
Further upstream discussion between Marek and Thomas decided this wasn't
fully baked and needed further work, so revert it before it hits mainline.

Misc fixes based on tests with an infoframe analyzer:
- checksum *does* include header bytes
- DIP enable & AVI infoframe are tied together in hw, so disable both
and make sure AVI frames are enabled first
- use every vsync flag for SPD frames to avoid reserved value in
frequency field when enabling both AVI & SPD

The commit 47356eb67285014527a5ab87543ba1fae3d1e10a introduced a
mechanism to record the backlight level only at disabling time, but it
also introduced a regression. Since intel_lvds_enable() may be called
without disabling (e.g. intel_lvds_commit() calls it unconditionally),
the backlight gets back to the last recorded value. For example, this
happens when you dim the backlight, close the lid and open the lid,
then the backlight suddenly goes to the brightest.
This patch fixes the bug by recording the backlight level always
when changed via intel_panel_set_backlight(). And,
intel_panel_{enable|disable}_backlight() call the internal function not
to update the recorded level wrongly.

Belongs in PCH enable instead. The duplication is worrying and the

At the point where we check, we can't do much about the failure, but it
can aid debugging. Note that the auto-train override bit will be reset
as part of normal mode setting with this patch if a pipe ever does get
stuck, but that's consistent with the workaround for CPT provided by the
hardware team. This patch helped catch the fact that the pipe wasn't
running in the !composite sync FDI case on my IVB SDV, so has already
shown to be useful.

Add two new fields to the intel_crtc struct for 3 pipe support: no_pll
and use_pll_a. The no_pll field is only set on the 3rd pipe to indicate
that it doesn't have a PLL of its own and so shouldn't try to write the
main PLL regs. The use_pll_a field controls which PLL pipe 3 will
share, A or B. The core code will try to share PLLs with whichever pipe
has the same timings, rejecting the mode set if none is found. This
means that pipe 3 must always be set after one of the other pipes has
been configured with real PLL settings.

2) when checking actual PLL enable, use the selected PLL number rather

Well almost anyway. IVB has 3 planes, pipes, transcoders, and FDI
interfaces, but only 2 pipe PLLs. So two of the pipes must use the same
pipe timings (e.g. 2 DP plus one other, or two HDMI with the same mode
and one other, etc.).

I've just discussed this quickly with Chris on irc and it's probably
best to just kill the list_empty early bailout. gpu_idle isn't a

without adding anything onto these lists is e.g. pageflip. There are
probably more.

We currently only round up the userspace size to the next page. We
assume that userspace hasn't made a mistake and requested a zero-length
gem object and all through our internal code we then presume that every
object is backed by at least a single page. Fix that oversight and
report EINVAL back to userspace if they try to create a zero length

This patch closes the following race:
We get a PM interrupt A, mask it, set dev_priv->iir = PM_A and kick of the
work item. Scheduler isn't grumpy, so the work queue takes rps_lock,
grabs pm_iir = dev_priv->pm_iir and pm_imr = READ(PMIMR). Note that
pm_imr == pm_iir because we've just masked the interrupt we've got.
Now hw sends out PM interrupt B (not masked), we process it and mask
it. Later on the irq handler also clears PMIIR.
Then the work item proceeds and at the end clears PMIMR. Because
(local) pm_imr == pm_iir we have
pm_imr & ~pm_iir == 0
so all interrupts are enabled.
Hardware is still interrupt-happy, and sends out a new PM interrupt B.
PMIMR doesn't mask B (it does not mask anything), PMIIR is cleared, so
we get it and hit the WARN in the interrupt handler (because
dev_priv->pm_iir == PM_B).
That's why I've moved the
WRITE(PMIMR, 0)
up under the protection of the rps_lock. And write an uncoditional 0
to PMIMR, because that's what we'll do anyway.
This races looks much more likely because we can arbitrarily extend
the window by grabing dev->struct mutex right after the irq handler
has processed the first PM_B interrupt.

Quoting Chris Wilson's more concise description:
"Ah I think I see the problem. As you point out we only mask the current
interrupt received, so that if we have a task pending (and so IMR != 0) we
actually unmask the pending interrupt and so could receive it again before the
tasklet is finally kicked off by the grumpy scheduler."
We need the hw to issue PM interrupts A, B, A while the scheduler is hating us
and refuses to run the rps work item. On receiving PM interrupt A we hit the
WARN because
dev_priv->pm_iir == PM_A | PM_B
Also add a posting read as suggested by Chris to ensure proper ordering of the
writes to PMIMR and PMIIR. Just in case somebody weakens write ordering.

I can't think of any sensible reason to limit this to a mask of 0x0f,
ie, SDVO_OUTPUT_{TMDS,RGB,CVBS,SVID}0.

I have no evidence for this byte being used this way, and lots of
counterexamples. Restore the struct to its empirical definition and
patch up gmbus setup to match.

The reference clock configuration must be done before any mode setting
can occur as all outputs must be disabled to change
anything. Initialize the clocks after turning everything off during
the initialization process.
Also, re-initialize the refclk at resume time.

I can't find any reference clocks which run at 96MHz as seems to be
indicated from the comments in this code.
