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

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

73 In order to configure the muxes behind a USB Type-C connector, the PMC firmware
76 device properties named "usb2-port-number" and "usb3-port-number". These

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"
