int cvs_csi_set_fmt (struct v4l2_subdev *sd , struct v4l2_subdev_state *state , struct v4l2_subdev_format *format );

---

🎀 ARGUMENTS 🎀

• sd — sub-device. the main character device, iykyk.
• state — state. yes bestie, it’s giving exactly what it says.
• format — desired / returned format. so it goes in wanting something and comes back with the format tea.

💅 DESCRIPTION 💅

okay so the whole vibe here is simple: it mirrors the sink format onto the source pad. no cap.

It accepts many media bus codes, and if something isn’t supported it falls back to Y8. periodt. It also normalizes the field setting, because we love a clean field setting.

⭐ RETURN ⭐

It returns 0. that’s it, that’s the whole return section 💅
