Lines Matching +full:dma +full:- +full:capable
3 Sh-/r-mobile and R-Car systems often have multiple identical DMA controller
4 instances, capable of serving any of a common set of DMA slave devices, using
6 SHDMA DT nodes to be placed under a DMA multiplexer node. All such compatible
7 DMAC instances have the same number of channels and use the same DMA
8 descriptors. Therefore respective DMA DT bindings can also all be placed in the
