Subject: [PATCH 07/10] drm/radeon: add new atombios encoder/transmitter interfaces
Date: Tue, 24 Feb 2015 09:24:01 +1000	[thread overview]
Message-ID: <1424733844-20185-8-git-send-email-airlied@gmail.com> (raw)
In-Reply-To: <1424733844-20185-1-git-send-email-airlied@gmail.com>

From: Dave Airlie <airlied@redhat.com>

These allow overriding the encoder id with the frontend,
we need this for setting up MST.
