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
24 Port nodes

30 For every USB Type-C connector under the mux-agent control on the system, there
31 is a separate child node under the PMC mux-agent device node. Those nodes do not
32 represent the actual connectors, but instead the "channels" in the mux-agent

70 Port Numbers
73 In order to configure the muxes behind a USB Type-C connector, the PMC firmware
74 needs to know the USB2 port and the USB3 port that is associated with the
75 connector. The driver extracts the correct port numbers by reading specific _DSD
76 device properties named "usb2-port-number" and "usb3-port-number". These
77 properties have integer value that means the port index. The port index number

94 be "fixed" from the mux-agent's point of view, which means the mux-agent driver
97 orientation. The driver uses a specific device properties "sbu-orientation"
98 (SBU) and "hsl-orientation" (data) to know if those lines are "fixed", and to
100 it can be one that is defined for the USB Type-C connector orientation: "normal"
