[Intel-gfx] [PATCH 3/9] drm/i915: create intel_digital_port and use it

Fri Oct 26 23:05:46 CEST 2012
From: Paulo Zanoni <paulo.r.zanoni at intel.com>
The goal is to have one single encoder capable of controlling both DP
and HDMI outputs. This patch just adds the initial infrastructure, no
functional changes.
Previously, both intel_dp and intel_hdmi were intel_encoders. Now,
these 2 structs do not have intel_encoder as members anymore. The new
struct intel_digital_port has intel_encoder as a member, and it also
includes intel_dp and intel_hdmi as members. In other words: see the
changes inside intel_drv.h: it's the most important change, everything
else is only to make it compile and work.
For now, each intel_digital_port is still only able to control one of
HDMI or DP, but not both together.
In the future we should also try to merge the common fields from
intel_dp and intel_hdmi (e.g., port).
