STRUCT SPINAND_OP_VARIANTS(9)

💅 struct spinand_op_variants(9) — like, the whole vibe

okay bestie, welcome to the Kernel API Manual ✨ specifically the page for struct spinand_op_variants, and no cap, this is one of those little structs that does so much behind the scenes. let's get into it 🫶

---

🌸 NAME 🌸

struct spinand_op_variants — SPI NAND operation variants. that's it, that's the name, she's literally described as "operation variants" and honestly? iconic of her 💅

---

✨ SYNOPSIS ✨

here's the shape of her, exactly as written:

struct spinand_op_variants {
    const struct spi_mem_op *ops;
    unsigned int nops;
 };

yes the indentation of that closing brace is a little quirky, don't come for her, she's been through a lot 😭

---

🎀 Members 🎀

• ops — the list of variants for a given operation. like a whole little lineup of options, one per transfer style 🔥
• nops — the number of variants. the headcount of that lineup, so the core knows how many she's got 🌈

---

🦋 Description 🦋

so here's the tea 🍓 — some operations, like read-from-cache / write-to-cache, have several variants depending on the number of IO lines you use to transfer data or address cycles. different line counts, different flavors, same general task 💖

this structure is the way to describe all the different variants a chip supports, and then let the core pick the best one based on what the SPI mem controller can actually do. so she's basically the menu, and the core is the one ordering 👑

ngl, that's a genuinely slay division of labor — the chip says "here's everything I can do," the core says "bet, I'll take the one that works" ✨
