STRUCT TYPEC_OPERATIONS(9)

💖 NAME 💖

struct typec_operations — USB Type-C Port Operations (yes bestie, it's the Kernel API Manual, we're in the big leagues now 👑)

✨ SYNOPSIS ✨

Okay so here's the whole squad, laid out exactly as the kernel gods wrote it:

struct typec_operations {
    int (*try_role)(struct typec_port *port, int role);
    int (*dr_set)(struct typec_port *port, enum typec_data_role role);
    int (*pr_set)(struct typec_port *port, enum typec_role role);
    int (*vconn_set)(struct typec_port *port, enum typec_role role);
    int (*port_type_set)(struct typec_port *port, enum typec_port_type
type);
    struct usb_power_delivery **(*pd_get)(struct typec_port *port);
    int (*pd_set)(struct typec_port *port, struct usb_power_delivery
*pd);
    int (*default_usb_mode_set)(struct typec_port *port, enum usb_mode
mode);
    int (*enter_usb_mode)(struct typec_port *port, enum usb_mode mode);
 };

Let me introduce you to every single one of these function pointers, no skips, no cap:

• try_role — sets the data role preference for a DRP port. It's giving "what do you wanna be when you grow up" energy 💅
• dr_set — Set Data Role. Literally just tells the port which data role it's on.
• pr_set — Set Power Role. Same vibe, but for power. ⚡
• vconn_set — Source VCONN. Yeah, it's the VCONN sourcing hook.
• port_type_set — Set port type. Slay, define yourself. 🦋
• pd_get — Get available USB Power Delivery Capabilities. It returns a struct usb_power_delivery **, iconic pointer-to-pointer behaviour fr fr.
• pd_set — Set USB Power Delivery Capabilities. Takes a struct usb_power_delivery *pd and just... sets it. Obsessed with the simplicity. 🎀
• default_usb_mode_set — USB Mode to be used by default with Enter_USB Message. The main character default vibe. 🌟
• enter_usb_mode — Change the active USB Mode. Not the default, the active one — important distinction bestie. 🔥
