[PATCH 0/8] drm/i915: Some DPLL crtc->state/config cleanups etc.

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

This series nukes some crtc->config and crtc->state uses from the
DPLL code. And I tossed in a few other random DPLL things I had lying around.

Ville Syrjälä (8):
  drm/i915: Set output_types to EDP for vlv/chv DPLL forcing
  drm/i915: Parametrize CBR_DPLLBMD_PIPE defines
  drm/i915: Eliminate crtc->config from VLV/CHV DPLL functions
  drm/i915: Pass crtc state to i9xx_enable_pll()
  drm/i915: Nuke the bogus kernel doc for i9xx_disable_pll()
  drm/i915: Add for_each_oldnew_intel_crtc_in_state()
  drm/i915: Shrink active_crtcs and active_pipes_changed to u8
  drm/i915: Eliminate crtc->state usage from DVO pipe tracking

[PATCH 1/8] drm/i915: Set output_types to EDP for vlv/chv DPLL forcing

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

When we enable the DPLL for the PPS kick, let's tell the DPLL code
we're dealing with an eDP output. This shouldn't really matter, but
it's more consistent with the way the DPLL is configured when we're
actually enabling the eDP port for real.

Hmm, all the prepared macros we have expect a 0-offset. (Otherwise you
get something like

(1 << (CBR_DPLLBMD_PIPE_B + (CBR_DPLLDMB_PIPE_C - CBR_DPLLDMB_PIPE_B)*((pipe) - PIPE_B)))

and at that point the numbers are much clearer and quicker to
reconstruct to match the docs.)

[PATCH 3/8] drm/i915: Eliminate crtc->config from VLV/CHV DPLL functions

the DPLL on VLV/CHV.

I was only going after the DPLL stuff. There's plenty more left.

Yeah, that's a PITA. I'm thinking we'll try to take care of that
with coccinelle or sed once the non-trivial cases are sorted.

Also looks like I missed i9xx_set_pll_dividers(). I'll have to fix that
one up as well to get the gmch DPLL code cleaned up.

[PATCH 6/8] drm/i915: Add for_each_oldnew_intel_crtc_in_state()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Add for_each_oldnew_intel_crtc_in_state() and use it in
intel_modeset_checks() to let is play with the intel_ types rather than
the drm_ types.

[PATCH 7/8] drm/i915: Shrink active_crtcs and active_pipes_changed to u8

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We only have three pipes, so 8 bits is more than sufficient to track
which is active. Also start using BIT() when populating them.

There's an hweight32(intel_state->active_crtcs & (drm_crtc_mask(for_crtc) - 1))

mixing drm_crtc_mask() and BIT(crtc->pipe) leaves a nasty taste. And
lots of hweight32() to cleanup.

Hmm. Looks very odd to be so isolated. It's treated as a bool which
explains why there's no corresponding clear_bit().

Hmm. Looks like that mixup goes even deeper in the SKL+ wm code. Not
sure I want to try untangling it all.

[PATCH 8/8] drm/i915: Eliminate crtc->state usage from DVO pipe tracking

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Change the DVO pipe tracking to maintain a bitmask in the top level
state, just as we do for active_crtcs. This gets rid of the ugly
intel_num_dvo_pipes() and its crtc->state and crtc->config usage.
