like, it's the little info bundle that tells the XDMA engine what's up with your specific platform. main character energy fr fr 👑

✨ SYNOPSIS ✨

struct xdma_platdata {
    u32 max_dma_channels;
    u32 device_map_cnt;
    struct dma_slave_map *device_map;
 };

look at her. iconic. three fields, zero drama 🎀 and yes, every single character above matters, so don't go editing it, bestie 😭

🦋 Members 🦋

okay so here's the member deets:

• max_dma_channels — the maximum dma channels in each direction 🔥 like, per direction, bestie. that's the cap. that's the limit. that's the vibe check 💅

ngl, that's the only member with its own little write-up here — the other two are chilling up in the synopsis and we're not out here inventing lore for them 🙈 keep it accurate, keep it cute.
