| description | Disclosed is USB type-c subsystem power management. 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.
本公开涉及USB C型子系统功率管理。基于硬件的唤醒检测和片上系统(SoC)固件支持用于服务固定显示端口(DP)和高清多媒体接口(HDMI)端口热插拔事件，其允许通用串行总线(USB)C型子系统在固定显示器没有流媒体时进入断电状态。在接收到响应于热插拔检测而针对固定显示流的显示软件发起的唤醒时，SoC USB C型固件触发退出低功率状态流，以上电USB C型子系统以处理显示业务。SoC USB C型固件能够在(一个或多个)固定显示器没有流媒体时自动重新进入低功率状态。 |
