Here's a pile of pending VLV/CHV DSI and DPLL patches I had lying around.
Most of these have been posted before. Would be nice to finally get them

I've tried to rebase things to account for BXT as well, but obviously
that part is not tested. I have tested this on a BYT FFRD8 which has
a DSI panel.

Apart from the VLV/CHV specific stuff, the main thing here is moving
the DSI PLL calculations to the .compute_config() phase. Another neat
thing is hooking up the panel fitter for DSI.

Ville Syrjälä (16):
  drm/i915: Throw out BUGs from DPLL/PCH functions
  drm/i915: Make {vlv,chv}_{disable,update}_pll() more similar
  drm/i915: Implement WaPixelRepeatModeFixForC0:chv
  drm/i915: Add a local pipe variable to vlv_enable_pll()
  drm/i915: assert_panel_unlocked() in chv_enable_pll()
  drm/i915: Remove the "three times for luck" trick from
  drm/i915: Setup DPLL/DPLLMD for DSI too on VLV/CHV
  drm/i915: Don't read out port_clock on CHV when DPLL is disabled
  drm/i915: Change lfsr_converts[] to u16
  drm/i915: Power down the DSI PLL before reconfiguring it
  drm/i915: Compute DSI PLL parameters during .compute_config()
  drm/i915: Fix CHV DSI PLL refclk during state readout
  drm/i915: Eliminate {vlv,bxt}_configure_dsi_pll()
  drm/i915: Dump pfit PGM_RATIOS as hex
  drm/i915: Hook up pfit for DSI
  drm/i915: Reject 'Center' scaling mode for eDP/DSI on GMCH platforms
