Merge tag 'nand/for-7.2' into mtd/next
* Extend SPI NAND continuous read to Winbond devices, which requires
numerous changes in the spi-{mem,nand} layers such as the need for a
secondary read operation template.
* Continuous reads in general have also been enhanced/fixed for avoiding
potential issues at probe time and at block boundaries.
Plus, there is the usual load of misc fixes and improvements.
