💅 stm32_spi_set_mbr (9) — the Kernel API Manual, but make it cute ✨

okay bestie, welcome to the Kernel API Manual entry for stm32_spi_set_mbr(9) — yes the whole manual name is in the title, iykyk 🎀 this one is short and sweet and honestly? it's giving "tiny function, big responsibilities" energy.

🌸 NAME 🌸

stm32_spi_set_mbr — sets/configure the baud rate divisor, but like, in host mode specifically 💅 no cap, that's the whole vibe.

---

✨ SYNOPSIS ✨

void stm32_spi_set_mbr (struct stm32_spi *spi , u32 mbrdiv );

look at her, so simple, so iconic 👑

🦋 ARGUMENTS 🦋

• spi — a pointer to the spi controller data structure 🫶 like, the whole controller's main character moment lives in here.
• mbrdiv — the baud rate divisor value 🌈 that's the number you're handing over, fr fr.

ngl bestie, this page keeps it extremely short — no return value section, no errors, no notes, no bugs, no author, no license. just vibes and a divisor. so don't go looking for lore that isn't there 🙈

and that's the page!! 🎀 brought to you from ./drivers/spi, dated October 2026, version stm32_spi_set_mbr(9) — mwah, slay, periodt 🌈💖
