-Subject: [PATCH] LF-323-2: drm/bridge/cdns: enhance link training stability
-
-Remove drm_dp_link_power_down from bridge_disable function,
-in case some DP sinks aren't follow DP 1.1 specification
-and can not exit the power saving state within 1 ms.
-Add drm_dp_link_power_up to bridge_enable function,
-make sure DP sinks are power up before link training.
