216  *(Fast) Read capabilities.
219  * then Quad SPI protocols before Dual SPI protocols, Fast Read and lastly
220  * (Slow) Read.
249  * Like (Fast) Read capabilities, Octal/Quad SPI protocols are preferred to the
294  *			read/write/erase/lock/unlock operations.
296  *			read/write/erase/lock/unlock operations.
297  * @read_reg:		read out the register.
299  * @read:		read data from the SPI NOR.

345  * @lock:		the lock for the read/write/erase/lock/unlock operations
346  * @rww:		Read-While-Write (RWW) sync lock
349  * @rww.ongoing_rd:	a read is ongoing on the chip
363  * @read_opcode:	the read opcode
364  * @read_dummy:		the dummy needed by the read operation
369  * @read_proto:		the SPI protocol for read operations
