ENUM SPINAND_BUS_INTERFACE(9)

💅 enum spinand_bus_interface 💅

okay so bestie, welcome to the Kernel API Manual ✨ this page is literally all about enum spinand_bus_interface — the SPI NAND bus interface types. it's giving "small enum, big responsibility" and honestly? iconic.

---

🌸 SYNOPSIS 🌸

so here's the whole thing, and yes, it's this short, don't come for me:

enum spinand_bus_interface {
    SSDR ,
    ODTR

};

that's it. two constants. two vibes. periodt. 💅

---

✨ Constants ✨

okay so these are the two members and what they actually mean, no cap:

• SSDR — the bus configuration that supports all the 1S-XX-XX operations, and yes babes that includes dual and quad 🦋 she's versatile, she's flexible, she does it all.
• ODTR — the bus configuration that supports only the 8D-8D-8D operations. that's it. that's the whole job. lowkey a one-trick pony but she does her trick flawlessly 👑

fr fr though: SSDR = the everything-girl, ODTR = strictly 8D-8D-8D. don't mix them up 💀
