Subject: [PATCH 6/9] drm/i915: Update intel_dp_compute_config() to handle compliance test requests
Date: Wed, 18 Feb 2015 20:00:34 -0700	[thread overview]
Message-ID: <1424314837-32434-7-git-send-email-tprevite@gmail.com> (raw)
In-Reply-To: <1424314837-32434-1-git-send-email-tprevite@gmail.com>

Adds provisions in intel_dp_compute_config() to accommodate compliance
testing. Mostly this invovles circumventing the automatic link configuration
parameters and allowing the compliance code to set those parameters as
required by the tests.

V2:
- N/A
V3:
- Moved color range check down under the compliance_exit tag
