From: Mythri P K <mythripk@xxxxxx> HDMI even if enabled by default should be powered on only when the cable is connected. This is supported by the Hot-plug feature. Now when HDMI is enabled the following steps are followed: -Display enable for HDMI is based on Hot-plug-detect(HPD). -It registers to the GPIO irq handler and checks if cable is connected, -If yes then it turns on HDMI -If an HPD interrupt is received the corresponding IRQ handler is called where it checks if it is a connect / disconnect based on which appropriate action is taken.
