Subject: [PATCH v2] drm/panel: sharp: lq101r1sx01: Send cmds to panel from link2
Date: Wed, 25 Mar 2015 14:56:42 +0800	[thread overview]
Message-ID: <1427266602-31905-1-git-send-email-markz@nvidia.com> (raw)

Sharp lq101r1sx01 panel works as left-right gang mode. So link2
should send cmds like "exit sleep mode", "set display on"
to panel as well.
