🦋 struct ws2401(9) — Kernel API Manual 🦋

okay so bestie, we're in the struct ws2401(9) manual page and honestly? it's giving "one little struct holding the whole vibe together." no cap. this is the state container for a panel controlled by the WS2401 controller, and yes u read that right 💅

✨ NAME ✨

struct ws2401 — the state container for a panel that's controlled by the WS2401 controller. that's it, that's the whole job, and it ate 🎀

---

🌸 SYNOPSIS 🌸

struct ws2401 {
    struct device *dev;
    struct mipi_dbi dbi;
    struct drm_panel panel;
    u32 width;
    u32 height;
    struct gpio_desc *reset;
    struct regulator_bulk_data regulators[2];
    bool internal_bl;
 };

like… look at her. iconic. every field is a little piece of the panel's whole personality 🫶

👑 Members 👑

bestie this is the part where we meet the cast. main character energy for every single one.

• dev — the container device. it's the whole device this struct lives inside, the literal home address 🏠
• dbi — the DBI bus abstraction handle. that's the bus situation, abstracted and ready to go 🚌
• panel — the DRM panel instance for this device. the actual panel representation, the star of the show ⭐
• width — the width of this panel, measured in mm. yes, millimeters, we're being precise 💅
• height — the height of this panel, also in mm. same energy, other axis 📏
• reset — the reset GPIO line. one little poke and she starts over 🙈
• regulators — the VCCIO and VIO supply regulators. that's a [2]-sized array because there are literally two of them, powering the whole situation ⚡
• internal_bl — a bool telling u if the internal backlight is being used. glow-up indicator, fr fr ✨
