Subject: [Intel-gfx] [PATCH v2 01/18] drm/dp: Dump downstream facing port caps
Date: Fri, 4 Sep 2020 14:53:37 +0300 [thread overview]
Message-ID: <20200904115354.25336-2-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20200904115354.25336-1-ville.syrjala@linux.intel.com>
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
It helps when the logs have a dump of the DFP capabilities.
v2: Move the dumping to the new helper
