jz4780_nemc_num_banks(9)

💅 jz4780_nemc_num_banks 💅

okay so bestie, welcome to the jz4780_nemc_num_banks page from the Kernel API Manual, section 9 (that's the manpage name, iykyk — it's literally the function we're talking about). she's short, she's sweet, she counts banks. let's get into it 🎀

---

✨ NAME ✨

jz4780_nemc_num_banks — count the number of banks referenced by a device 🧮✨

like literally just counting. no drama. she tallies up how many banks a device is pointing at, and that's her whole personality. icon behavior tbh 👑

---

🌸 SYNOPSIS 🌸

unsigned int jz4780_nemc_num_banks (struct device *dev );

that's it. that's the whole signature. copy it exactly, don't @ me 💅

---

🦋 ARGUMENTS 🦋

• dev — the device you want to count banks for. and bestie, listen, this is not optional vibes: it must be a child of the NEMC. if it's not a NEMC child, this whole thing is not it, so double-check that before you come crying to me 😭

---

⭐ RETURN ⭐

she returns the number of unique NEMC banks referred to by the specified NEMC child device. 💖

and "unique" is doing a lot of heavy lifting here, so let me spell it: unique means that a device that references the same bank multiple times in its "reg" property will only count once. like yes girl we see you in there four times, but you're one bank, you count as one. no double dipping, no inflation, no cap. 🫶

👀 SEE ALSO 👀

• the kernel file ./drivers/memory/jz4780-nemc.c — go read her, she's the main character of this whole thing 📖✨
• jz4780_nemc_set_type(9)
• jz4780_nemc_assert(9)

these two are her besties, they're all in the same friend group, go say hi 🌈

---

lowkey a reminder bestie: dev has to be a child of the NEMC, that's not a suggestion, that's the requirement 💀

and that's the whole page!! no notes, she ate and left no crumbs 🔥
