omap_nand_data_in_pref(9)

💅 omap_nand_data_in_pref(9) — like, the manual, but make it make sense

Okay so bestie, gather round, because this one is a whole function and it's living in the Kernel API Manual. It's called omap_nand_data_in_pref and it's literally about getting NAND data in using the prefetch engine. No cap, that's the whole vibe. 🦋

✨ NAME ✨

omap_nand_data_in_pref — NAND data in using prefetch engine

Like… it pulls data in and it uses the prefetch engine to do it. That's it, that's the function. 🎀

---

🌸 SYNOPSIS 🌸

void omap_nand_data_in_pref (struct nand_chip *chip , void *buf ,
       unsigned int len , bool force_8bit );

Returns void, so like… don't expect anything back, she gives and gives and gets nothing in return 😭 (jk, the data goes into buf, we'll get to that).

---

💖 ARGUMENTS 💖

• chip — NAND chip. Like, the actual chip struct you're working with. She's the main character here 👑
• buf — output buffer where NAND data is placed into. This is where the good stuff lands, bestie ✨
• len — length of transfer. How much data we're moving, iykyk.
• force_8bit — force 8-bit transfers. Yes, force. It's giving "we're doing 8-bit whether you like it or not" 💀
