Subject: [PATCH 1/2] drm/i915/icl: Configure MG PHY gating for HDMI ports too
Date: Fri,  2 Nov 2018 21:26:55 +0200	[thread overview]
Message-ID: <20181102192656.4472-2-imre.deak@intel.com> (raw)
In-Reply-To: <20181102192656.4472-1-imre.deak@intel.com>

The MG PHY clock gating needs to be configured for Type C
static/fixed/legacy HDMI ports the same way it's configured for Type C
static/fixed/legacy and aternate mode DP ports, fix this.
