From: Pratyush Yadav <p.yadav@ti.com> With multiple contexts, there needs to be a different DMA channel for each context. Earlier, the DMA channel name was hard coded to "rx0" for the sake of simplicity. Generate the DMA channel name based on its index and get the channel corresponding to the context.
