With Display Stream Compression, bit error
in pixel stream can turn into a significant
corruption on the screen. DP1.4 adds support for
Forward Eror correction which uses Reed-Solomon
codes with which the sink can detect small
numbers of bit errors in compressed stream.

This series is rebased on top of:

Srivatsa, Anusha (5):
  drm/dp/fec: DRM helper for Forward Error Correction
  i915/dp/fec: Check for FEC Support
  drm/i915/fec: Set FEC_READY in FEC_CONFIGURATION
  i915/dp/fec: Configure the Forward Error Correction bits.
  drm/i915/fec: Disable FEC state.
