nand_setup_interface(9)

💅 nand_setup_interface(9) ✨

okay so bestie, welcome to the Kernel API Manual — this one's nand_setup_interface(9), and no, it's not the boring one, it's actually kind of iconic 🎀

🌸 NAME 🌸

nand_setup_interface — Setup the best data interface and timings 💫

🦋 SYNOPSIS 🦋

int nand_setup_interface (struct nand_chip *chip , int chipnr );

✨ ARGUMENTS ✨

• chip — The NAND chip 👑 (the main character, obviously)
• chipnr — Internal die id 🎀

💖 DESCRIPTION 💖

so what this does is, like, configure what has been reported to be the best data interface and NAND timings supported by the chip and the driver 🫶 like it's literally taking the glow-up report and actually applying it. both the chip and the driver have to be on board, iykyk.

Returns 0 for success ✨ or a negative error code otherwise 😭 (not me getting a negative error code, embarrassing).
