STRUCT AT_DMA_SLAVE(9)

🌸 struct at_dma_slave (9) — Kernel API Manual 🌸

okay bestie, welcome to the at_dma_slave page 💅 this one lives in the Kernel API Manual, so you already know it's the real deal. it's all about the controller-specific info for a slave — short page, but every single crumb matters, so let's go 🫶

✨ NAME ✨

struct at_dma_slave — controller-specific information about a slave. that's it, that's the whole vibe 😌

---

🦋 SYNOPSIS 🦋

struct at_dma_slave {
    struct device           *dma_dev;
    u32 cfg;
 };

look at her. two members. immaculate. no notes ✨

🎀 Members 🎀

• dma_dev — the required DMA master device. like, required required, bestie. no dma_dev, no deal 💀
• cfg — the platform-specific initializer for the CFG register. your platform, your rules 🧚
