Subject: [PATCH v17 6/7] drm/rockchip: cdn-dp: retry to check sink count
Date: Sun, 5 Feb 2017 15:55:01 +0800 [thread overview]
Message-ID: <1486281302-28200-7-git-send-email-zyw@rock-chips.com> (raw)
In-Reply-To: <1486281302-28200-1-git-send-email-zyw@rock-chips.com>
Sometimes the Dock is disconnected, but cdn_dp_encoder_disable is not
triggered by DRM. For example, unplug the Dock in console mode, and
re-plug it again, the cdn_dp_event_work will try to get the sink count
of Dock, since the DP is still active. But the Dock has been powered
down, it need re-power on, and wait for a while until it is ready to
DPCD communication.
