4 Intel North Mux-Agent
10 North Mux-Agent is a function of the Intel PMC firmware that is supported on
13 platforms that allow the mux-agent to be configured from the operating system
16 The North Mux-Agent (aka. Intel PMC Mux Control, or just mux-agent) driver
18 (drivers/platform/x86/intel_scu_ipc.c). The driver registers with the USB Type-C
19 Mux Class which allows the USB Type-C Controller and Interface drivers to
22 Device modes. The driver is located here: drivers/usb/typec/mux/intel_pmc_mux.c.
