Merge tag 'mtd/fixes-for-7.0-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux

Pull MTD fixes from Miquel Raynal:

 - In SPI NOR, there was an issue with the RDCR capability, leading to
   several platforms no longer capable of using it for wrong reasons
   (the follow-up commit renames the helper to avoid future confusion)

 - NAND controller drivers needed to be improved to fix some timings, a
   locking schenario and avoid certain operations during panic writes

 - The Spear600 DT binding conversion was done partially, leading to
   several warnings which have individually been fixed

 - Tudor gets replaced by Takahiro for the SPI NOR maintainance

 - Plus two more misc fixes
