STRUCT ROCKCHIP_USB2PHY_PORT(9)

💖 struct rockchip_usb2phy_port(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ — we're looking at struct rockchip_usb2phy_port today and honestly? she's doing a lot. this is the usb-phy port data struct, and by the end of this page you're gonna know every single field in her little group chat 🫶

✨ NAME ✨

struct rockchip_usb2phy_port — usb-phy port data. that's the whole vibe. port data. iconic. 💅

🌸 SYNOPSIS 🌸

struct rockchip_usb2phy_port {
    struct phy      *phy;
    unsigned int    port_id;
    bool suspended;
    bool vbus_attached;
    bool host_disconnect;
    int bvalid_irq;
    int id_irq;
    int ls_irq;
    int otg_mux_irq;
    struct mutex    mutex;
    struct delayed_work chg_work;
    struct delayed_work otg_sm_work;
    struct delayed_work sm_work;
    const struct    rockchip_usb2phy_port_cfg *port_cfg;
    struct notifier_block   event_nb;
    enum usb_otg_state      state;
    enum usb_dr_mode        mode;
};

like, look at her. so many fields. so much going on. let's do a vibe check on every single one 💜

🦋 Members 🦋

the basics 🎀

• phy — generic phy. that's it. that's the pointer. she's just a girl 💅
• port_id — flag for otg port or host port. so you know which one you're dealing with, ykwim?
• suspended — phy suspended flag. is she napping? this tells you 🦋

the status flags ✨

• vbus_attached — otg device vbus status. literally just: is the vbus attached or not 🔥
• host_disconnect — usb host disconnect status. highkey important bestie, don't skip her 😭

the IRQ numbers 🔔

• bvalid_irq — IRQ number assigned for vbus valid rise detection. she detects the rise, no cap ✨
• id_irq — IRQ number assigned for ID pin detection.
• ls_irq — IRQ number assigned for linestate detection. linestate! she's watching 👀
• otg_mux_irq — IRQ number which multiplex otg-id/otg-bvalid/linestate irqs to one irq in otg-port. okay so she's out here multiplexing three irqs into one, that's giving main character energy fr fr 👑

the locking + work stuff 🧚

• mutex — for register updating in sm_work. keep it locked bestie, no data races on my watch 🙈
• chg_work — charge detect work.
• otg_sm_work — OTG state machine work.
• sm_work — HOST state machine work.

the config + events + state 🌈

• port_cfg — port register configuration, assigned by driver data. she didn't pick her own config, the driver data assigned it. iykyk 💜
• event_nb — hold event notification callback. she's holding it. gently. 🫶
• state — define OTG enumeration states before device reset. the before-reset era, we remember 🎀
• mode — the dr_mode of the controller. periodt. ⭐

lowkey reminder bestie: this page is listing the fields exactly as they are — I'm not adding behaviour that isn't here, so don't come for me 😭
