STRUCT V4L2_MBUS_CONFIG_MIPI_CSI2(9)

🌸 struct v4l2_mbus_config_mipi_csi2 — MIPI CSI-2 data bus configuration 🌸

okay bestie, so this is a page straight out of the Kernel API Manual, and it's genuinely just describing one lil struct that tells the kernel how a MIPI CSI-2 data bus is wired up 💖. no cap, it's short, it's sweet, and it ate.

💅 NAME 💅

struct v4l2_mbus_config_mipi_csi2 — literally the MIPI CSI-2 data bus configuration, that's the whole vibe 🦋

---

✨ SYNOPSIS ✨

struct v4l2_mbus_config_mipi_csi2 {
    unsigned int flags;
    unsigned char data_lanes[V4L2_MBUS_CSI2_MAX_DATA_LANES];
    unsigned char clock_lane;
    unsigned char num_data_lanes;
    bool lane_polarities[1 + V4L2_MBUS_CSI2_MAX_DATA_LANES];
    enum v4l2_mbus_csi2_cphy_line_orders_type
line_orders[V4L2_MBUS_CSI2_MAX_DATA_LANES];
 };

like, look at her. iconic. copy it exactly, don't you dare retype it from memory 🙈

🎀 Members 🎀

• flags — the media bus (V4L2_MBUS_*) flags, your classic little flag field 🌈
• data_lanes — an array of physical data lane indexes. yes bestie, physical, it's giving hardware-level realness 💀
• clock_lane — the physical lane index of the clock lane ⭐
• num_data_lanes — how many data lanes there are. the count. the number. periodt 👑
• lane_polarities — the polarity of the lanes, and the order here is the same as the physical lanes 🫶
• line_orders — the line order of the data lanes, and again the order is the same as the physical lanes 🌸

ok so tiny thing but it matters: for both lane_polarities and line_orders, the order matches the physical lanes. don't shuffle them, that's the whole point 💅

like the whole friend group showed up to the function name 💖 love that for them.

and that's the page bestie, no notes 🧚 this one lives down in ./include/media, and it's dated October 2026, so like… future energy honestly 🔥 stay slay, stay configured properly, and remember: lane order matters 💜
