STRUCT PCH_VBUS_GPIO_DATA(9)

💖 NAME 💖

okay bestie, welcome to the Kernel API Manual, section 9 — this is struct pch_vbus_gpio_data(9). And what is it? Literally the structure holding GPIO informaton (yes, that's the exact spelling from the page, iconic) for detecting VBUS. That's the whole name, no cap.

🦋 SYNOPSIS 🦋

Here's the struct in all its glory, copied exactly so nothing gets twisted, fr fr:

struct pch_vbus_gpio_data {
    struct gpio_desc        *port;
    int intr;
    struct work_struct      irq_work_fall;
    struct work_struct      irq_work_rise;
 };

🌸 MEMBERS 🌸

Member-by-member, because we're thorough like that:

• port — gpio descriptor for the VBUS GPIO. That's the one.
• intr — gpio interrupt number. The number, the whole number, nothing but the number.
• irq_work_fall — Structure for WorkQueue. Yes, that's literally what it says, and we're keeping it.
• irq_work_rise — Structure for WorkQueue. Same energy, different work item.

And that's the whole vibe, bestie: from ./drivers/usb/gadget/udc, dated October 2026, for struct pch_vbus_gpio_data(9). Go off, queen. 👑✨
