stm32_spi_dma_config(9)

💅 stm32_spi_dma_config(9) 💅

okay so bestie, this is the stm32_spi_dma_config(9) page from the Kernel API Manual — and the way that it just configures the dma slave channel depending on the current transfer bits_per_word? obsessed. tiny page, very specific job, no cap. ✨

🌸 NAME 🌸

stm32_spi_dma_config — configure dma slave channel depending on current transfer bits_per_word.

---

🎀 SYNOPSIS 🎀

void stm32_spi_dma_config (struct stm32_spi *spi , struct dma_chan
       *dma_chan , struct dma_slave_config *dma_conf , enum
       dma_transfer_direction dir );

---

🦋 ARGUMENTS 🦋

bestie, there are four things coming in — keep them all cute and correct:

• spi — pointer to the spi controller data structure. main character struct energy, honestly.
• dma_chan — pointer to the DMA channel.
• dma_conf — pointer to the dma_slave_config structure.
• dir — direction of the dma transfer.
