nand_reset_op(9)

💅 nand_reset_op — the Kernel API Manual, bestie edition ✨

okay so real talk, we're looking at nand_reset_op from the Kernel API Manual, and honestly? it's a little baddie with one job and it does it. no notes. 🎀

---

🌸 NAME 🌸

nand_reset_op — literally just do a reset operation. that's it, that's the whole vibe 💅

---

✨ SYNOPSIS ✨

int nand_reset_op (struct nand_chip *chip );

---

🫶 ARGUMENTS 🫶

• chip — the NAND chip, your main character for this whole function 💖

---

🦋 DESCRIPTION 🦋

so here's the tea, bestie: this function sends a RESET command and then waits for the NAND to be ready before it comes back home to you. it's giving "text me when you get there" energy, fr fr 😭

note the caveat though: this function does not select/unselect the CS line. it's not doing that for you, you have to handle that yourself, no cap 🙈

it returns 0 on success, and a negative error code otherwise. slay when it's zero, cry when it's negative 💀
