okay so bestie, welcome to the Kernel API Manual ✨ this one's a lil function page from the kernel's own doc squad, and honestly it's a shortie but a goodie 💅

🌸 ARGUMENTS 🌸

• dchan — the DMA channel pointer 💫 that's it, that's the whole argument list. she's the main character of this page fr fr.

ngl bestie, if you only remember one thing: zynqmp_dma_free_chan_resources is the cleanup bestie — she takes the struct dma_chan *dchan and gives those channel resources their freedom 🕊️

and that's a wrap, babe 🎀 this page sources from ./drivers/dma/xilinx, dated October 2026, and it's filed under the Kernel API Manual — so go forth and free those channel resources, periodt 💅✨
