zynqmp_dma_device_config(9)

👑 NAME 👑

From the Kernel API Manual, bestie: this is zynqmp_dma_device_config(9), and the function is literally zynqmp_dma_device_config - Zynqmp dma device configuration. That’s the whole name section, periodt. 💅

✨ SYNOPSIS ✨

int zynqmp_dma_device_config (struct dma_chan *dchan , struct
       dma_slave_config *config );

Lowkey just read it like a little spellsheet: function name, then the args. ✨

💖 ARGUMENTS 💖

• dchan — DMA channel. Yes bestie, that’s the DMA channel — the one and only.
• config — DMA device config. The DMA device config is coming through, make way.

🌈 RETURN 🌈

0 always. Not “sometimes,” not “if the vibes are right” — always. 😌✨
