#define	DT_NVMEM_CELLS_HAS_IDX(node_id, idx)   DT_PROP_HAS_IDX(node_id, nvmem_cells, idx)
	Test if a node has an nvmem-cells phandle-array property at a given index.
#define	DT_NVMEM_CELLS_HAS_NAME(node_id, name)   DT_PROP_HAS_NAME(node_id, nvmem_cells, name)
	Test if a node has an nvmem-cell-names array property hold a given name.
#define	DT_NUM_NVMEM_CELLS(node_id)   DT_PROP_LEN(node_id, nvmem_cells)
	Get the number of elements in an nvmem-cells property.
#define	DT_NVMEM_CELL_BY_IDX(node_id, idx)   DT_PHANDLE_BY_IDX(node_id, nvmem_cells, idx)
