Pull MTD updates from Brian Norris:
 "Core:

   - WARN (in some cases) when a struct mtd_info is registered multiple
     times; in the past this was "supported", but it's still error prone
     for future development.  There's only one ugly case of this left in
     the tree (that we're aware of) and the owners are aware of the
     problems there.

   - fix potential deadlock in the blkdev removal path NOTE: the
     (potential) deadlock was introduced in a for-stable patch.  This
     one is also marked for -stable.

   - ioctl(BLKPG) compat_ioctl support; resolves issues with 32-bit user
     space vs 64-bit kernel space

   - Set MTD parent device correctly throughout the tree, so the tree
     structure appears correctly in sysfs; many drivers were missing
     this (soft) requirement

   - Move device tree partitions (ofpart) into a dedicated 'partitions'
     subnode; this helps to disambiguate whether a node is a partition
     or some other auxiliary data

   - Improve error handling for partitioning failures

  NAND:

   - General: Increase timeout period, for corner-case systems with
     less-than-accurate jiffies

   - Fix OF-based autoloading of several NAND drivers when built as
     modules

   - pxa3xx_nand:
      - Rework timing configuration to be more dynamic
      - Refactor PM support

   - brcmnand: prepare for NorthStar 2 support (ARM64, 16-bit NAND
     chips)

   - sunxi_nand: refactoring and a few bug fixes

   - vf610: new NAND driver

   - FSMC: add SW BCH support; support common NAND DT bindings

   - lpc32xx_slc: refactor and improve timing calculations logic

   - denali: support for rev 5.1

  SPI NOR:

   - Layering improvements

   - Added Winbond lock/unlock support

   - Added mtd_is_locked() (i.e., ioctl(MEMISLOCKED)) support

   - Increase full-chip-erase timeout linearly with flash size

   - fsl-quadspi: fix compile for non-ARM architectures

   - New flash support"
