That is easier to read with curly braces even if they are strictly not
necessary

	if (ddr_vaddr) {
		dma_free_coherent(&dev->dev, info->mem[2].size,
			info->mem[2].internal_addr, info->mem[2].addr);
	}

That wants to be:
     
	ddr_vaddr = dma_alloc_coherent(&dev->dev, len, &ddr_paddr,
					GFP_KERNEL | GFP_DMA);

Otherwise this looks very clean and readable now and I can't spot any
technical problems with it anymore.

Please fixup the nits and feel free to add
