[Intel-gfx] [PATCH v3 0/4] drm/i915: Start cleaning up the DPLL ID mess

[Ville Syrjala]

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

Start to clean up the mess around DPLL IDs a bit by removing
the nasty assumption that the index of the DPLL in the
arrays matches its ID. Fortunately we did have a WARN
i nthere to cathc mistakes, but better to not has such
silly assumptions i nthe first place.

There's still a lot of mess left since the DPLL IDs in
the hardware are a mess as well. Eg. the index of the
register instance often differs from the index used
to select the DPLL in clock routing thing. So we could
probably clean up more of that, perhaps by declaring
separate IDs for each PLL for each use case...

v2:
- the trivial patches were already merged
- introduce pll->index
- add another patch for for_each_shared_dpll()
- add another patch s/dev_priv/i915/

v3:
- deal with pll->index in debugfs code
- rebase due to other changes

Ville Syrjälä (4):
  drm/i915: Stop requiring PLL index == PLL ID
  drm/i915: Decouple I915_NUM_PLLS from PLL IDs
  drm/i915: Introduce for_each_shared_dpll()
  drm/i915: s/dev_priv/i915/ in the shared_dpll code
