The DT for virtualized hosts have dma-cells == 2 where the second parameter is the ATYPE for the channel. In case of dma-cells == 1 we can configure the ATYPE as 0 (reset value). The ATYPE defined for j721e are: 0: pointers are physical addresses (no translation) 1: pointers are intermediate addresses (PVU) 2: pointers are virtual addresses (SMMU) Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Link: https://lore.kernel.org/r/20200218143126.11361-3-peter.ujfalusi@ti.com Signed-off-by: Vinod Koul <vkoul@kernel.org>
