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

While debugging problems on DDI platforms I got tired of the crap
caused by the the dual personality DDI encoders, so I went ahead
and split them into separate HDMI and DP encoders.

As usual, the hole got a bit deeper after I noticed that I had to
kill intel_prepare_ddi() as well.

This also needs the check_digital_port_conflicts() patch [1] because
otherwise kms_setmode results in a dead machine.

Series avaialbe there (with [1] included):

Ville Syrjälä (15):
  drm/i915: Pass the correct encoder to intel_ddi_clk_select() with MST
  drm/i915: Check max number of lanes when registering DDI ports
  drm/i915: Store max lane count in intel_digital_port
  drm/i915: Remove pointless 'ddi_translations' local variable
  drm/i915: Eliminate duplicated skl_get_buf_trans_dp()
  drm/i915: Pass around dev_priv for ddi buffer programming
  drm/i915: Add BUILD_BUG_ON()s for DDI translation table sizes
  drm/i915: Reject >9 ddi translation entried if port != A/E on SKL
  drm/i915: Kill intel_prepare_ddi()
  drm/i915: Split the problematic dual-role DDI encoder into two
  drm/i915: Explicitly use ddi bug trans entry 9 for hdmi
  drm/i915: Split DP/eDP/FDI and HDMI/DVI DDI buffer programming apart
  drm/i915: Add a sanity check for 'hdmi_default_entry'
  drm/i915: Get the iboost setting based on the port type
  drm/i915: Simplify intel_ddi_get_encoder_port()
