[Intel-gfx] [PATCH 0/8] drm/i915: cdclk/voltage_level cleanups and fixes

[Ville Syrjala]

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

A bit of refactoring around the cdclk/voltage_level stuff.

I also spotted that we were miscalculating the voltage level
on MTL in two different places, so included fixes (or rather
power optimizations) for those.

Ville Syrjälä (8):
  drm/i915/cdclk: s/-1/~0/ when dealing with unsigned values
  drm/i915/cdclk: Give the squash waveform length a name
  drm/i915/cdclk: Remove the assumption that cd2x div==2 when using
    squashing
  drm/i915/cdclk: Rewrite cdclk->voltage_level selection to use tables
  drm/i915/mtl: Fix voltage_level for cdclk==480MHz
  drm/i915: Split intel_ddi_compute_min_voltage_level() into platform
    variants
  drm/i915/mtl: Calculate the correct voltage level from port_clock
  drm/i915: Simplify intel_ddi_compute_min_voltage_level()
