✨ nand_choose_best_timings ✨

okay so bestie, we're in the Kernel API Manual 🌸 and this lil function is nand_choose_best_timings — it's giving "matchmaker for NAND parts" energy 💅

💖 NAME 💖

nand_choose_best_timings — pick up the best NVDDR or SDR timings that both the NAND controller and the NAND chip support 🫶

like, it's literally the vibes check between your controller and your chip, and it only ships them if both say yes. no cap.

🎀 SYNOPSIS 🎀

int nand_choose_best_timings (struct nand_chip *chip , struct
nand_interface_config *iface );

🦋 ARGUMENTS 🦋

  • chip — the NAND chip 💜 that's your main character right there.
  • iface — the interface configuration. and yes, it can eventually be updated ✨ (so don't clutch it too hard, it might get rewritten on you 🙈).

🌈 DESCRIPTION 🌈

okay so here's the tea ☕:

If specific timings are provided, use them. Periodt. 💅 Like, you already told it what you want, so it's not gonna argue.

Otherwise — and only otherwise — it goes and retrieves the supported timing modes from ONFI information 🔥. It's digging through the chip's own receipts to figure out what it can actually handle.

⭐ SEE ALSO ⭐

Kernel file ./drivers/mtd/nand/raw/nand_base.c — that's the mothership, iykyk 🚀

and literally the whole extended friend group 👑:

and that's the whole page bestie, go forth and pick some timings 💖✨🎀

sign-off szn 🧚: this one lives under ./drivers/mtd/nand/raw and the manual itself is dated October 2026 ⭐ — slay, see u in the next man page 🫶💜
