STRUCT SPINAND_USER_OTP_OPS(9)

💅 struct spinand_user_otp_ops(9) — SPI NAND OTP methods for user area

okay bestie, welcome to the Kernel API Manual page for struct spinand_user_otp_ops ✨ — literally the little bundle of SPI NAND OTP methods for the user area, and no cap, it's giving "function pointers that do exactly what they say on the tin" 🎀

✨ SYNOPSIS ✨

no thoughts, just vibes and a struct 🫶 here she is, character for character:

struct spinand_user_otp_ops {
    int (*info)(struct spinand_device *spinand, size_t len, struct
otp_info *buf, size_t *retlen);
    int (*lock)(struct spinand_device *spinand, loff_t from, size_t
len);
    int (*erase)(struct spinand_device *spinand, loff_t from, size_t
len);
    int (*read)(struct spinand_device *spinand, loff_t from, size_t len,
size_t *retlen, u8 *buf);
    int (*write)(struct spinand_device *spinand, loff_t from, size_t
len, size_t *retlen, const u8 *buf);
 };

like, she's a whole struct of callbacks and honestly? main character energy 💜

🦋 Members 🦋

• info — get the OTP area information 💖 she's the one who tells you what's up in there.
• lock — lock an OTP region 🔒 once it's locked, that's periodt.
• erase — erase an OTP region 🧹 bye bye bits.
• read — read from the SPI NAND OTP area 📖 get those bytes bestie.
• write — write to the SPI NAND OTP area ✍️ put those bytes in.
