Subject: [Intel-gfx] [PATCH 3/5] drm/i915: Power up combo PHY lanes for for HDMI as well
Date: Thu, 28 Jan 2021 17:59:46 +0200 [thread overview]
Message-ID: <20210128155948.13678-3-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20210128155948.13678-1-ville.syrjala@linux.intel.com>
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
Currently we only explicitly power up the combo PHY lanes
for DP. The spec says we should do it for HDMI as well.
