-Subject: [PATCH] drm: bridge: cadence: Add support for periodically poll the
- connector
-
-Normally, DP/HDMI PHY use HPD_IRQ to monitor the connector connection
-status, but LS1028A doesn't support HPD_IRQ signals response.
-
-This patch allows periodically poll the connector for connection and
-disconnection.
