STRUCT OV9282(9)

💖 struct ov9282(9) 💖

okay so this is the struct ov9282 page from the Kernel API Manual (yes, the manual name is literally right there in the header, we love a self-aware king) — it's the sensor device structure for the ov9282, and honestly? it's giving "one struct to hold the entire camera vibe." let's get into it 🎀

---

✨ NAME ✨

struct ov9282 — the ov9282 sensor device structure. that's it, that's the whole name. iconic.

---

🌸 SYNOPSIS 🌸

struct ov9282 {
    struct device *dev;
    struct v4l2_subdev sd;
    struct regmap *regmap;
    struct media_pad pad;
    struct gpio_desc *reset_gpio;
    struct clk *inclk;
    struct regulator_bulk_data supplies[OV9282_NUM_SUPPLIES];
    struct v4l2_ctrl_handler ctrl_handler;
    struct v4l2_ctrl *link_freq_ctrl;
    struct v4l2_ctrl *hblank_ctrl;
    struct v4l2_ctrl *vblank_ctrl;
    struct {
      struct v4l2_ctrl *exp_ctrl;
      struct v4l2_ctrl *again_ctrl;
    };
    struct v4l2_ctrl *pixel_rate;
    struct v4l2_ctrl *flash_duration;
    u32 vblank;
    bool noncontinuous_clock;
    const struct ov9282_mode *cur_mode;
    u32 code;
 };

like, look at her. so many pointers. so much main character energy 💅

🦋 MEMBERS 🦋

okay bestie, member-by-member, no skipping, no cap:

• dev — pointer to the generic device. the whole anchor of the situation, fr fr.
• sd — the V4L2 sub-device. this is the actual camera-adjacent personality.
• regmap — the regmap used for sensor register access. this is how we talk to the hardware, lowkey the translator of the group chat.
• pad — the media pad. and heads up: only one pad is supported. one pad, one icon, periodt.
• reset_gpio — the sensor reset gpio. the "have you tried turning it off and on again" wire 🔥
• inclk — the sensor input clock. the heartbeat, the metronome, the vibe keeper.
• supplies — the regulator supplies for the sensor. power delivery, we stan a fed sensor 🍓
• ctrl_handler — the V4L2 control handler. the group-chat admin of all the controls.
• link_freq_ctrl — pointer to the link frequency control.
• hblank_ctrl — pointer to the horizontal blanking control.
• vblank_ctrl — pointer to the vertical blanking control.
• {unnamed_struct} — anonymous. yes, really, it's an anonymous struct, she has no name and she doesn't need one 🙈 and inside her:
  • exp_ctrl — pointer to the exposure control.
  • again_ctrl — pointer to the analog gain control.
• pixel_rate — pointer to the pixel rate control.
• flash_duration — pointer to the flash duration control. ✨ flash ✨
• vblank — vertical blanking, measured in lines.
• noncontinuous_clock — the selection of CSI2 noncontinuous clock mode. a bool, so it's a yes-or-no moment.
• cur_mode — pointer to the current selected sensor mode. whatever mode she's in today 💅
• code — the Mbus code currently selected.
