💅 stm32h7_spi_disable — from the Kernel API Manual, bestie

okay so picture this: you're deep in the kernel, the SPI controller is doing its thing, and you need it to stop doing its thing. That's this function. It's giving "turn the lights off on your way out" energy, and honestly? Iconic. 🎀

✨ NAME ✨

stm32h7_spi_disable — disable the SPI controller. That's it, that's the whole vibe. No cap.

🌸 SYNOPSIS 🌸

void stm32h7_spi_disable (struct stm32_spi *spi );

literally one call. no return value. no drama. 💅

🦋 ARGUMENTS 🦋

  • spi — a pointer to the spi controller data structure 🫶. Like, the actual SPI thing you're about to shut down. Hand it over and let it cook.

⭐ DESCRIPTION ⭐

So here's the tea ☕: the RX-Fifo gets flushed when the SPI controller is disabled. That's the whole description, bestie — short, sweet, and honestly a little ominous if you were emotionally attached to whatever was sitting in that fifo. 😭 It's gone. Flushed. Bye. 🙈

fr fr though — if you had data chilling in the RX-Fifo, disabling the controller is gonna yeet it. Just so you know. 💀
