    drm/i915: use adjusted_mode instead of mode for checking the 6bpc force flag

in ironlake_crtc_mode_set() to be dropped.

Fix the call in ironlake_crtc_mode_set() again, and while at it, also fix
the new, copy-pasted haswell_crtc_mode_set() to use adjusted_mode.

Paulo Zanoni bb523fc08d drm/i915: convert PIPE_CLK_SEL to transcoder
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.

Paulo Zanoni a5c961d1f3 drm/i915: add TRANSCODER_EDP
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.

Paulo Zanoni 8361663420 drm/i915: don't call Haswell PCH code when we can't or don't need
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).

It is worth noticing that we are not considering IBX/CPT possible on

consider IBX/CPT as a possibility with a Haswell CPU, but this was
never tested, I really doubt it will work with the current code and we

Note that on IBX the rawclk is variable according to Bspec, but
everyone is using 125MHz. The rawclk is fixed to 125MHz on CPT, but
luckily we still have the same register available. On hsw, different
variants have different clocks, hence we need to check the register.

Since other pieces are driven by the rawclock, too, keep the little
helper in a central place.

    drm/i915: check PPS regs for sanity when using eDP

v2:
- Unlock the PP regs as the very first thing. This is a required w/a
  for cpu eDP on port A, and generally a good idea.
- Fixup the panel power control port selection bits.

v3: Paulo Zanoni noticed that I've fumbled the computation of the spec
limit values. Fix them up. We've also noticed that the t8/t9 values in
the vbt/bios-programmed pp are much larger than any limits. My guess
is that this is to conceal any backlight enable/disable delays. So by
using the much shorter limits from the spec, which only concerns the
sink, we risk that we might display before the backlight is fully on,
or disable the output while the backlight still has afterglow. I've
figured I don't care too much, since this will only happen when both
the pp regs are not programmed, and the vbt tables don't contain
anything useful.

v4: Don't set the port selection bits on hsw/LPT, they don't exist any
more.

v5: Fixup spelling issues in comments, as noticed by Jesse Barnes.

Daniel Vetter a7c9655fdd drm/i915: use the new dp train delay helpers
Only really required for dp 1.2. I've hoped this would help with some
link training woes I'm fighting, but alas those are only dp 1.1
devices.

Also move a comment that went misplaced in the recent refactorings to
the right spot again.

Daniel Vetter 1a644cd47c drm: extract dp link train delay functions from radeon
This requires a few changes since that dpcd value is above the
range currently cached by radeon. I've check the dp specs, and
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
that i915.ko uses.

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
consume in train_cr and train_ce will always be fresh.

To avoid needless diff-churn, #define the old size of dpcd as the new
one and keep it around.

v2: Alex Deucher noticed one place where I've forgotten to replace 8
with DP_RECEIVER_CAP_SIZE.

Safe for the minor difference that the intel versions get an offset

Jani Nikula 1d508706ea drm/i915: Create generic intel_panel for LVDS and eDP
Create a generic struct intel_panel for sharing a data structure and code
between eDP and LVDS panels. Add the new struct to intel_connector so that
later on we can have generic EDID and mode reading functions with EDID
caching that transparently fallback to fixed mode when EDID is not
available.

Add intel_panel as a dummy first, and move data (such as the mentioned
fixed mode) to it in later patches.

Jani Nikula 62165e0def drm/i915/lvds: Move some connector specific info across from the encoder
As there is 1:1 mapping between encoder and connector for the LVDS, the
goal is to simply reduce the amount of noise within the connector
functions, i.e. we split the encoder/connector for LVDS as best we can and
try to only operate on the LVDS connector from the connector funcs and the
LVDS encoder form the encoder funcs.
