#define DT_DMAS_CTLR_BY_IDX(node_id, idx)   DT_PHANDLE_BY_IDX(node_id, dmas, idx)
 Get the node identifier for the DMA controller from a dmas property at an index.
 
#define DT_DMAS_CTLR_BY_NAME(node_id, name)    DT_PHANDLE_BY_NAME(node_id, dmas, name)
 Get the node identifier for the DMA controller from a dmas property by name.
 
#define DT_DMAS_CTLR(node_id)   DT_DMAS_CTLR_BY_IDX(node_id, 0)
 Equivalent to DT_DMAS_CTLR_BY_IDX(node_id, 0)
 
#define DT_INST_DMAS_CTLR_BY_IDX(inst, idx)    DT_DMAS_CTLR_BY_IDX(DT_DRV_INST(inst), idx)

 Get a DT_DRV_COMPAT instance's DMA specifier's cell value by name.
 
#define DT_DMAS_HAS_IDX(node_id, idx)    IS_ENABLED(DT_CAT4(node_id, _P_dmas_IDX_, idx, _EXISTS))
 Is index "idx" valid for a dmas property?
 
#define DT_INST_DMAS_HAS_IDX(inst, idx)    DT_DMAS_HAS_IDX(DT_DRV_INST(inst), idx)
 Is index "idx" valid for a DT_DRV_COMPAT instance's dmas property?
