[PATCH 11/20] drm/amd/display: Implement DCE analog link encoders

[Alexandre Demers]

> We support two kinds of analog connections:
> 
> 1. VGA, which only supports analog signals:
> For VGA, we need to create a link encoder that only works with the
> DAC without perturbing any digital transmitter functionality.
> This is achieved by the new dce110_analog_link_encoder_construct.
> 
> 2. DVI-I, which allows both digital and analog signals:
> The DC code base only allows 1 encoder per connector, and the
> preferred engine type is still going to be digital. So, for DVI-I
> to work, we need to make sure the pre-existing link encoder can
> also work with analog signals.

  I have the same comment about the use of "dce110_" prefix under general/global DCE code that I left on the previous patch.
  
  For consistency with the current code, I understand why this prefix is used, but I'd gladly clean this up once the patches have landed in if there is a common agreement.
