Subject: [PATCH 13/14] drm/amd/display: Use pwrseq instance to determine eDP instance
Date: Sat, 20 Mar 2021 09:46:55 +0800	[thread overview]
Message-ID: <20210320014656.23350-14-solomon.chiu@amd.com> (raw)
In-Reply-To: <20210320014656.23350-1-solomon.chiu@amd.com>

From: Jake Wang <haonan.wang2@amd.com>

[Why & How]
Link index doesn't always correspond to the appropriate eDP instance.
We can assume lower link index is a lower eDP instance and set panel
control instance accordingly.
