2958620abc drm/i915/display: drop lots of unnecessary #include i915_drv.h 
With the PCH macros switched to use struct intel_display, we have a
number of files that no longer need struct drm_i915_private or anything
else from i915_drv.h anymore. Remove the #include, and add the missing
includes that were previously implicit.

v2: Drop even more of the includes

4e9b0ac17f drm/i915/display: pass struct intel_display to PCH macros 
Now that INTEL_PCH_TYPE() and HAS_PCH_*() macros are under display, and
accept a struct intel_display pointer, use that instead of struct
drm_i915_private pointer in display code.

This is done naively by running:

$ sed -i 's/\(INTEL_PCH_TYPE\|HAS_PCH_[A-Z0-9_-]*\)([^)]*)/\1(display)/g' \
  $(find drivers/gpu/drm/i915/display -name "*.c")

and fixing the fallout, i.e. removing unused local i915 variables and
adding display variables where needed.

v2: Rebase

e8828d7fdb drm/i915: Move intel_disable_shared_dpll() into ilk_pch_post_disable() 
On ILK-IVB only PCH outputs use shared dplls. Move the relevant
intel_disable_shared_dpll() into ilk_pch_post_disable() to make
that clear (and if we extend the dpll mgr to cover all plls we need
different enable/disable points anyway for the PCH vs. CPU eDP cases).
The intel_enable_shared_dpll() counterpart was already in
ilk_pch_enable() anyway, so this is the more symmetric place for the
disable as well.

struct intel_dpll_hw_state has a spot for all possible
PLL registers across all platforms (well, apart from
cx0/snps). This makes it rather confusing when trying to
figure out which members belong to which platform(s).

Split the struct up into five different platform specific
sub-structures. For now this will actually increase the size
a little bit as we have to duplicate a few members from
skl to icl, but that will be remedied soon when we turn
the thing into a union.

3eb08ea58e drm/i915: s/PIPECONF/TRANSCONF/ 
Rename PIPECONF to TRANSCONF to make it clear what it actually
applies to.

While the usual convention is to pick the earliers name I think
in this case it's more clear to use the later name. Especially
as even the register offset is in the wrong range (0x70000 vs.
0x60000) and thus makes it look like this is per-pipe.

There is one place in gvt that's doing something with TRANSCONF
while iterating with for_each_pipe(). So that might not be doing
the right thing for TRANSCODER_EDP, dunno. Not knowing what it
does I left it as is to avoid breakage.

5ac421a9ec drm/i915: Give CPU transcoder timing registers TRANS_ prefix 
Name the CPU transcoder timing registers TRANS_FOO rather than
just FOO. This is the modern name, after the pipe/transcoder split
happened. Makes it a bit more obvious whether you pass in a pipe or
a transcoder.

PIPESRC is a bit special as it's a pipe register, even though it
lives in the transcoder registers range (0x60000 instead of 0x70000).

And BCLRPAT I suppose is a transcoder register (since it has something
to do with the timing generator), but it doesn't even exist after gen4
so I left it to use the only name it ever had in bspec.

And while at it let's pass in the correct enum in few more
places why don't we. Although in all those places the distinction
doesn't matter.

801543b259 drm/i915: stop including i915_irq.h from i915_trace.h 
Turns out many of the files that need i915_reg.h get it implicitly via
{display/intel_de.h, gt/intel_context.h} -> i915_trace.h -> i915_irq.h
-> i915_reg.h. Since i915_trace.h doesn't actually need i915_irq.h,
makes sense to drop it, but that requires adding quite a few new
includes all over the place.

Prefer including i915_reg.h where needed instead of adding another
implicit include, because eventually we'll want to split up i915_reg.h
and only include the specific registers at each place.

Also some places actually needed i915_irq.h too.

We need to make framestart_delay dynamic for DRRS on PCH

we get state check+dump for it. Will also allow us to get

718cc87e16 drm/i915: Introduce lpt_pch_disable() 
Let's add lpt_pch_disable() as the counterpart to
lpt_pch_enable().

Note that unlike the ilk+ code the fdi_link_train()
and fdi_disable() calls are still left directly in
intel_crt.c. If we wanted to move those we'd need to
add lpt_pch_pre_enable(). But the two fdi direct fdi
calls are pretry symmetric so it doesn't seem too bad
to just keep them as is.

9e68fa88b8 drm/i915: Move iCLKIP readout to the pch code 
Move the lpt_get_iclkip() call from hsw_crt_get_config()
since that's where we have the lpt_program_iclkip() call
as well.

Tehcnically this isn't perhaps quite right since iCLKIP
is providing the CRT dotclock. So one can argue all of
it should be directly in intel_crt.c. But since the CRT
port is the only one on the PCH sticking it all into the
PCH code seems OK.

it had to checked manually.
