Abstract
Hardware-based wake detection and system-on-chip (SoC) firmware support for servicing fixed display port (DP) and High Definition Multimedia Interface (HDMI) port hot plug events which allow a Universal Serial Bus (USB) Type-C subsystem to go into a powered off state while the fixed display is not streaming. Upon receiving a display software-initiated wake for fixed display streaming in response to a hot plug detect, the SoC USB Type-C firmware triggers exit low-power state flow to power up the USB USB Type-C subsystem to handle the display traffic. The SoC USB Type-C firmware has the capability to autonomously re-enter the low power state when the fixed display(s) are not streaming.
