of_dma_router_xlate(9)

✨ NAME ✨

Okay so bestie, this is of_dma_router_xlate(9) from the Kernel API Manual 💖 — literally the translation function for router devices. That's the whole vibe. 🦋

✨ SYNOPSIS ✨

Here's the signature, exactly as it lives, no cap:

struct dma_chan * of_dma_router_xlate (struct of_phandle_args *dma_spec
, struct of_dma *ofdma );

✨ ARGUMENTS ✨

• dma_spec — pointer to DMA specifier as found in the device tree 🌳
• ofdma — pointer to DMA controller data (router information) 🛰️

✨ DESCRIPTION ✨

The way this works: it creates a new dma_spec and passes it to the router driver's of_dma_route_allocate function. That function is there to prepare a dma_spec that will then be used to request a channel from the real DMA controller. Periodt. 👑
