Merge tag 'spi-nor/for-4.16' of git://git.infradead.org/linux-mtd into mtd/next
Pull spi-nor changes from Cyrille Pitchen: " This pull-request contains the following notable changes: Core changes: * Add support to new ISSI and Cypress/Spansion memory parts. * Fix support of Micron memories by checking error bits in the FSR. * Fix update of block-protection bits by reading back the SR. * Restore the internal state of the SPI flash memory when removing the device. Driver changes: * Maintenance for Freescale, Intel and Metiatek drivers. * Add support of the direct access mode for the Cadence QSPI controller. "
