I honestly don't think we do because it would be totally redundant with
the macro name, ie.

+#define SPINAND_PAGE_READ_FROM_CACHE_DTR_OP(addr, ndummy, buf, len, freq) \
+       SPI_MEM_OP(SPI_MEM_OP_CMD(0x0d, 1),                             \
+                  SPI_MEM_DTR_OP_ADDR(2, addr, 1),                     \
+                  SPI_MEM_DTR_OP_DUMMY(ndummy, 1),                     \
+                  SPI_MEM_DTR_OP_DATA_IN(len, buf, 1),                 \
+                  SPI_MEM_OP_MAX_FREQ(freq))

is IMHO better than

+#define SPINAND_PAGE_READ_FROM_CACHE_DTR_OPCODE 0x0d
+#define SPINAND_PAGE_READ_FROM_CACHE_DTR_OP(addr, ndummy, buf, len, freq) \
+       SPI_MEM_OP(SPI_MEM_OP_CMD(SPINAND_PAGE_READ_FROM_CACHE_DTR_OPCODE, 1), \
+                  SPI_MEM_DTR_OP_ADDR(2, addr, 1),                     \
+                  SPI_MEM_DTR_OP_DUMMY(ndummy, 1),                     \
+                  SPI_MEM_DTR_OP_DATA_IN(len, buf, 1),                 \
+                  SPI_MEM_OP_MAX_FREQ(freq))
