7809e5ae35 drm/i915/ivb: Move WaCxSRDisabledForSpriteScaling w/a to atomic check
Determine whether we need to apply this workaround at atomic check time
and just set a flag that will be used by the main watermark update
routine.

Moving this workaround into the atomic framework reduces
ilk_update_sprite_wm() to just a standard watermark update, so drop it
completely and just ensure that ilk_update_wm() is called whenever a
sprite plane is updated in a way that would affect watermarks.

3a05f5e2e7 drm/i915/skl: Eliminate usage of pipe_wm_parameters from SKL-style WM (v3)
Just pull the info out of the state structures rather than staging
it in an additional set of structures.  To make this more
straightforward, we change the signature of several internal WM
functions to take the crtc state as a parameter.

v2:
 - Don't forget to skip cursor planes on a loop in the DDB allocation
   function to match original behavior.  (Ander)
 - Change a use of intel_crtc->active to cstate->active.  They should
   be identical, but it's better to be consistent.  (Ander)
 - Rework more function signatures to pass states rather than crtc for
   consistency. (Ander)

v3:
  - Add missing "+ 1" to skl_wm_plane_id()'s 'overlay' case. (Maarten)
  - Packed formats should pass '0' to drm_format_plane_cpp(), not 1.
    (Maarten)
  - Drop unwanted WARN_ON() for disabled planes when calculating data
    rate for SKL.  (Maarten)

4969d33ed9 drm/i915/skl: Simplify wm structures slightly (v2)
A bunch of SKL watermark-related structures have the cursor plane as a
separate entry from the rest of the planes.  Since a previous patch
updated I915_MAX_PLANES such that those plane arrays now have a slot for
the cursor, update the code to use the new slot in the existing plane
arrays and kill off the cursor-specific structures.

There shouldn't be any functional change here; this is just shuffling
around how the data is stored in some of the data structures.  The whole
patch is generated with Coccinelle via the following semantic patch:

31409e97ef drm/i915: Determine I915_MAX_PLANES from plane enum
Let the compiler figure out what I915_MAX_PLANES is from 'enum plane' so
that we don't need a separate #define.

While we're at it, add the cursor plane to the enum.  This will cause
I915_MAX_PLANES to now include the cursor plane in its count (it didn't
previously).   This change is safe since we currently only use this
value in array declarations (never in the actual code logic); we just
wind up allocating slightly more memory than we need to.  A followup
patch will cause various parts of the code to start using the extra
array element where appropriate.

(This patch probably should have been squashed with the followup patch,
but I couldn't figure out how to get Coccinelle to modify enum
declarations...)

7221fc333d drm/i915: Eliminate usage of pipe_wm_parameters from ILK-style WM (v2)
Just pull the info out of the CRTC state structure rather than staging
it in an additional structure.

Note that we use cstate->active rather than intel_crtc->active which may
appear to be a change in behavior.  However since we're no longer trying
to recalculate watermarks during the "pipe off" stage of a modeset,
intel_crtc->active and cstate->active should always be identical when
watermarks are calculated (at least for ILK-style platforms).

v2: Clarify reasoning for cstate->active and add a WARN_ON to the code
    to assert that it really is always identical to intel_crtc->active
    as expected.

37d9078b9b drm/i915: Drop redundant watermark programming
In commit

        commit e4ca061275
        Author: Patrik Jakobsson <patrik.jakobsson@linux.intel.com>
        Date:   Wed Jul 8 15:31:52 2015 +0200

            drm/i915: Don't forget to mark crtc as inactive after disable

we added extra watermark updates to all of the .crtc_disable()
entrypoints to avoid problems problems with system resume on SKL.  Those
disable entrypoints are currently called in just two places in the
driver: intel_atomic_commit (i.e., during a modeset) and
intel_crtc_disable_noatomic (which is called during hardware readout).
It seems that this extra watermark recalculation should only be
important in the latter case (which happens during a resume operation);
the former case should always have appropriate watermark programming
happening at other points in the modeset sequence.

Let's move the watermark update out of the .crtc_disable() entrypoints
and place it directly in intel_crtc_disable_noatomic() so that it only
happens on S3 resume and not during a regular modeset (since the
existing watermark handling should properly update watermarks during
normal atomic commits).

5507faeb03 drm/i915: make backlight hooks connector specific
Previously we've relied on having basically one backlight and one
backlight type per platform. This is already a bit quirky with PMIC PWM
support on VLV/CHV platforms with MIPI DSI. In the foreseeable future
we'll have at least DPCD based backlight control on eDP and DCS command
based backlight control on MIPI DSI. Backlight is becoming more and more
connector specific, so reflect this fact by making the backlight control
hooks connector specific.

This enables further work to reuse generic backlight code in
intel_panel.c while adding more specific backlight code accessed via the
hooks.

Also store it in kHz under dev_priv like we do for cdlck since it's not

standard/convenient for some things.

Imre also pointed out that we currently fail to read czclk on VLV, which
means the PFI credit programming isn't working as expected.

aad941d53f drm/i915: Always use crtc_ timings when dealing with adjustead_mode
The adjustead_mode crtc_ timings are what we will program into the hardware,
so it's those timings we should be looking practically everywhere.

The normal and crtc_ timings should differ only when stere doubling is
used. In that case the normal timings are the orignal non-doubled
timigns, and crtc_ timings are the doubled timings used by the hardware.

The only case where we continue to look at the normal timings is when we
pass the adjusted_mode to drm_match_{cea,hdmi}_mode() to find the VIC.
drm_edid keeps the modes aronund in the non-double form only, so it
needs the non-double timings to match against.

Done with sed
's/adjusted_mode->\([vhVH]\)/adjusted_mode->crtc_\1/g'
's/adjusted_mode->clock/adjusted_mode->crtc_clock/g'
with a manual s/VDisplay/vdisplay/ within the comment in intel_dvo.c
