 Get the node identifier for the DMA controller from a dmas property by name.
 
#define DT_DMAS_CTLR(node_id)
 Equivalent to DT_DMAS_CTLR_BY_IDX(node_id, 0)
 
#define DT_INST_DMAS_CTLR_BY_IDX(inst, idx)
 Get the node identifier for the DMA controller from a DT_DRV_COMPAT instance's dmas property at an index.
 
#define DT_INST_DMAS_CTLR_BY_NAME(inst, name)
 Get the node identifier for the DMA controller from a DT_DRV_COMPAT instance's dmas property by name.
 
#define DT_INST_DMAS_CTLR(inst)
 Equivalent to DT_INST_DMAS_CTLR_BY_IDX(inst, 0)
 
#define DT_DMAS_CELL_BY_IDX(node_id, idx, cell)

#define DT_DMAS_HAS_IDX(node_id, idx)
 Is index "idx" valid for a dmas property?
 
#define DT_INST_DMAS_HAS_IDX(inst, idx)
 Is index "idx" valid for a DT_DRV_COMPAT instance's dmas property?
 
#define DT_DMAS_HAS_NAME(node_id, name)
 Does a dmas property have a named element?
 
#define DT_INST_DMAS_HAS_NAME(inst, name)
