Pull MTD updates from Brian Norris:
 "Generic MTD:

   - populate the MTD device 'of_node' field (and get a proper 'of_node'
     symlink in sysfs)

     This yielded some new helper functions, and changes across a
     variety of drivers

   - partitioning cleanups, to prepare for better device-tree based
     partitioning in the future

     Eliminate a lot of boilerplate for drivers that want to use
     OF-based partition parsing

     The DT bindings for this didn't settle yet, so most non-cleanup
     portions are deferred for a future release

  NAND:

   - embed a struct mtd_info inside struct nand_chip

     This is really long overdue; too many drivers have to do the same
     silly boilerplate to allocate and link up two "independent"
     structs, when in fact, everyone is assuming there is an exact 1:1
     relationship between a NAND chips struct and its underlying MTD.
     This aids improved helpers and should make certain abstractions
     easier in the future.

     Also causes a lot of churn, helped along by some automated code
     transformations

   - add more core support for detecting (and "correcting") bitflips in
     erased pages; requires opt-in by drivers, but at least we kill a
     few bad implementations and hopefully stave off future ones

   - pxa3xx_nand: cleanups, a few fixes, and PM improvements

   - new JZ4780 NAND driver

  SPI NOR:

   - provide default erase function, for controllers that just want to
     send the SECTOR_ERASE command directly

   - fix some module auto-loading issues with device tree
     ("jedec,spi-nor")

   - error handling fixes

   - new Mediatek QSPI flash driver

  Other:

   - cfi: force valid geometry Kconfig (finally!)

     This one used to trip up randconfigs occasionally, since bots
     aren't deterred by big scary "advanced configuration" menus

  More? Probably. See the commit logs"
