STRUCT SPI_DELAY(9)

✨ struct spi_delay(9) ✨

okay so this is a page from the Kernel API Manual (yes, the kernel has lore too 💅) and it's all about struct spi_delay — literally just the little struct that carries SPI delay information. that's it. that's the whole vibe. tiny struct, big main character energy. 🎀

---

🌸 NAME 🌸

struct spi_delay — SPI delay information. no cap, that's the entire name section. short and iconic.

---

🦋 SYNOPSIS 🦋

bestie, here's the whole thing, verbatim, don't touch it:

struct spi_delay {
  #define SPI_DELAY_UNIT_USECS    0;
  #define SPI_DELAY_UNIT_NSECS    1;
  #define SPI_DELAY_UNIT_SCK      2;
    u16 value;
    u8 unit;
 };

like look at her. the #defines are sitting inside the struct, the semicolons after the numbers are just... there, and the closing }; has one (1) extra space before it. we don't ask questions, we just copy it exactly. 🫶

---

💜 Members 💜

• value — the value for the delay. the actual number. the moment. ⭐
• unit — the unit for the delay. like, what value is even measured in. the context. the iykyk. 🔥

ok that's the whole page, go read the friends too, they're all in ./include/linux/spi 💖

and that's a wrap!! 🎀 this one came out of ./include/linux/spi, dated October 2026, and it's the struct spi_delay(9) page — slay, go forth and delay ur SPI stuff correctly ✨💅🦋
