✨ stm32_spi_transfer_one_setup(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's a page about stm32_spi_transfer_one_setup, and yes the name is a whole mouthful, we're not gonna pretend otherwise 🫶

🌸 NAME 🌸

stm32_spi_transfer_one_setup — the common setup that handles transferring a single spi_transfer, whether that's going down the DMA road or the interrupts road 🚗✨

🦋 SYNOPSIS 🦋

int stm32_spi_transfer_one_setup (struct stm32_spi *spi , struct
spi_device *spi_dev , struct spi_transfer *transfer );

🎀 ARGUMENTS 🎀

• spi — pointer to the spi controller data structure 👑 the main character of this whole function, fr
• spi_dev — pointer to the spi device 🎧
• transfer — pointer to spi transfer 💫 that's the single transfer we're setting up
