STRUCT MIPI_DSI_DEVICE_INFO(9)

💖 struct mipi_dsi_device_info(9) 💖

okay bestie, so this is a page from the Kernel API Manual — literally the struct mipi_dsi_device_info(9) entry — and it's way less scary than the name makes it look, i promise. it's giving "tiny little template struct that just wants to help you make a device" energy. 🦋

---

✨ NAME ✨

struct mipi_dsi_device_info — the template for creating a mipi_dsi_device. yes, that's the whole pitch. it's the blueprint, not the building. 🎀

---

✨ SYNOPSIS ✨

here's the whole struct, and it's lowkey smol:

struct mipi_dsi_device_info {
    char type[DSI_DEV_NAME_SIZE];
    u32 channel;
    struct device_node *node;
 };

like. three members. that's it. we love a concise icon. 💅

---

✨ Members ✨

• type — the DSI peripheral chip type. think of it as the what even is this thing label. 🌸
• channel — the DSI virtual channel assigned to the peripheral. the assigned lane, so to speak. 😌
• node — a pointer to the OF device node, or NULL. so it either points at a device node or it doesn't, and NULL is a totally valid vibe here. 🫶

---

✨ Description ✨

so this struct is meant to be populated (like, filled in by you, bestie) and then passed to mipi_dsi_device_new to create a new DSI device. that's the entire job. it's the little info packet you hand over so your device can be born ✨

no cap, that's it. it's a carrier bag for three pieces of info. iconic behaviour. 🌈

aaaand that's the page!! 🎀 this cutie lives in the ./include/drm corner of the kernel tree, and it's dated October 2026 — so when you see struct mipi_dsi_device_info(9) floating around with that date on it, that's me, that's the one. mwah 💋✨
