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

Here's my second installment of SKL+ cdclk stuff. I've picked up Clint's latest
SKL/KBL cdclk patch and expanded on it quite a bit. After this series we're
capable of actually changing the DPLL0 VCO frequency dynamically, and a lot of
the code gets a much more uniform feel to it between SKL/KBL vs. BXT. This
should make it possible to land some future hardware work on top as well,
without making the code an awful mess.

Series available here:

Clint Taylor (1):
  drm/i915/skl: SKL CDCLK change on modeset tracking VCO

Ville Syrjälä (20):
  drm/i915: Fix BXT min_pixclk after state readout
  drm/i915: Move the SKL DPLL0 VCO computation into
    intel_dp_compute_config()
  drm/i915: Extract skl_calc_cdclk()
  drm/i915: Actually read out DPLL0 vco on skl from hardware
  drm/i915: Report the current DPLL0 vco on SKL/KBL
  drm/i915: Allow enable/disable of DPLL0 around cdclk changes on SKL
  drm/i915: Keep track of preferred cdclk vco frequency on SKL
  drm/i915: Beef up skl_sanitize_cdclk() a bit
  drm/i915: Unify SKL cdclk init paths
  drm/i915: Move SKL+ DBUF enable/disable to display core init/uninit
  drm/i915: Make 308 and 671 MHz cdclks more accurate on SKL
  drm/i915: Rename skl_vco_freq to cdclk_pll.vco
  drm/i915: Store cdclk PLL reference clock under dev_priv
  drm/i915: Extract bxt DE PLL enable/disable from broxton_set_cdclk()
  drm/i915: Store BXT DE PLL vco and ref clocks in dev_priv
  drm/i915: Update cached cdclk state from broxton_init_cdclk()
  drm/i915: Rewrite broxton_get_display_clock_speed() in terms of the DE
    PLL vco/refclk
  drm/i915: Make bxt_set_cdclk() operate in terms of the current vs
    target DE PLL vco
  drm/i915: Replace bxt_verify_cdclk_state() with a more generic cdclk
    check
  drm/i915: Set BXT cdclk to minimum initially
