🦋 SYNOPSIS 🦋

int cdns_spi_setup_transfer(struct spi_device *spi, struct spi_transfer *transfer);

---

🌸 ARGUMENTS 🌸

• spi — a pointer to the spi_device structure. Like, the device in question, periodt 💅
• transfer — a pointer to the spi_transfer structure, which is the little info packet telling you about the setup parameters for the next transfer 👑

🧚 DESCRIPTION 🧚

So what does it actually do? It sets the operational mode of the SPI controller for the next SPI transfer, and it sets the requested clock frequency. That's the whole vibe. No cap, that's it. ⭐
