Merge tag 'spi-nor/for-4.15' of git://git.infradead.org/l2-mtd
This pull-request contains the following notable changes: From Cyrille: " Core changes: * Introduce system power management support. * New mechanism to select the proper .quad_enable() hook by JEDEC ID, when needed, instead of only by manufacturer ID. * Add support to new memory parts from Gigadevice, Winbond, Macronix and Everspin. Driver changes: * Maintainance for Cadence, Intel, Mediatek and STM32 drivers. "
