Pull MTD updates from Miquel Raynal:
 "MTD changes:

   - There's been no major core change, just a bunch of driver related
     improvements.

     Amongst them the conversion to of_property_present() for
     non-boolean properties, the addition of the support for Fujitsu
     MB85RS128TY FRAM, a couple of improvements to the phram driver and
     the usual load of misc changes.

  Raw NAND changes:

   - A new controller driver, from Nuvoton, has been merged

   - Bastien Curutchet has contributed a series improving the Davinci
     controller driver, both on the organization of the code, but also
     on the performance side. The binding has also been converted to
     yaml, received a new OOB layout and now supports on-die ECC engines

   - The Qualcomm controller driver has been deeply cleaned to extract
     some parts of the code into a shared file with the Qualcomm SPI
     memory controller

   - Aside from these main changes, the Cadence binding has been
     converted to yaml, the brcmnand controller driver has received a
     small fix, otherwise some more minor changes have also made their
     way in

  SPI NAND changes:

   - The SPI NAND subsystem has seen a great improvement, with the
     advent of DTR operations (DDR operations, which may be extended to
     the address cycles). The first vendor driver to benefit from these
     improvements is the Winbond driver

   - A new manufacturer driver is added SkyHigh, with a new constraint
     for the core, it is impossible to disable the on-die ECC engine

   - A Foresee device is also now supported

  SPI NOR changes:

   - Several flash entries have been added: Atmel AT25SF321, Spansion
     S28HL256T and S28HL02GT

   - Support for vcc-supply regulators and their DT bindings has been
     added

   - The mx25u25635f entry has been dropped. The flash shares its ID
     with mx25u25645g and both parts have an SFDP table. Removing their
     entry lets them be driven by the generic SFDP-based driver"
