Only when cable is connected and transmission is possible HDMI Phy should move to TX_ON state. This is supported by the Hot-plug feature. Now when HDMI is enabled the following steps are followed: -It registers to the GPIO irq handler -If an HPD interrupt is received the corresponding IRQ handler is called where it checks if it is a connect / disconnect based on which PHY is moved to appropriate state.
