STRUCT FIMC_VARIANT(9)

✨ struct fimc_variant(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 — today's main character is struct fimc_variant, and it's literally the little cheat-sheet that tells you what a given FIMC device variant can and can't do. no cap.

---

🌸 NAME 🌸

struct fimc_variant — FIMC device variant information 🎀

---

🦋 SYNOPSIS 🦋

struct fimc_variant {
    unsigned int    has_inp_rot:1;
    unsigned int    has_out_rot:1;
    unsigned int    has_mainscaler_ext:1;
    unsigned int    has_cam_if:1;
    unsigned int    has_isp_wb:1;
    const struct fimc_pix_limit *pix_limit;
    u16 min_inp_pixsize;
    u16 min_out_pixsize;
    u16 hor_offs_align;
    u16 min_vsize_align;
 };

look at her. a whole vibe check for a hardware revision 💅

ngl, that's the whole page — every bit flag, every constraint, every alignment value. nothing skipped, bestie. periodt. 🫶
