Subject: [PATCH v5 05/16] drm/i915: Use the cpu_transcoder in intel_hdcp to toggle HDCP signalling
Date: Thu, 5 Mar 2020 15:12:25 -0500 [thread overview]
Message-ID: <20200305201236.152307-6-sean@poorly.run> (raw)
In-Reply-To: <20200305201236.152307-1-sean@poorly.run>
From: Sean Paul <seanpaul@chromium.org>
Instead of using intel_dig_port's encoder pipe to determine which
transcoder to toggle signalling on, use the cpu_transcoder field already
stored in intel_hdmi.
This is particularly important for MST.
