Pull mtd updates from Boris Brezillon:
 "SPI NOR Core changes:
   - Parse the 4BAIT SFDP section
   - Add a bunch of SPI NOR entries to the flash_info table
   - Add the concept of SFDP fixups and use it to fix a bug on MX25L25635F
   - A bunch of minor cleanups/comestic changes

  NAND core changes:
   - kernel-doc miscellaneous fixes.
   - Third batch of fixes/cleanup to the raw NAND core impacting various
     controller drivers (ams-delta, marvell, fsmc, denali, tegra,
     vf610):
      * Stop to pass mtd_info objects to internal functions
      * Reorganize code to avoid forward declarations
      * Drop useless test in nand_legacy_set_defaults()
      * Move nand_exec_op() to internal.h

      * Pass the CS line to be selected in struct nand_operation
      * Make ->select_chip() optional when ->exec_op() is implemented
      * Deprecate the ->select_chip() hook
      * Move the ->exec_op() method to nand_controller_ops
      * Move ->setup_data_interface() to nand_controller_ops
      * Deprecate the dummy_controller field
      * Fix JEDEC detection
      * Provide a helper for polling GPIO R/B pin

      * Flag 1.8V AC chips with a broken GET_FEATURES(TIMINGS)

  Raw NAND controllers drivers changes:
   - Ams-delta:
      * Fix the error path
      * SPDX tag added
      * May be compiled with COMPILE_TEST=y
      * Conversion to ->exec_op() interface
      * Drop .IOADDR_R/W use
      * Use GPIO API for data I/O
   - Denali:
      * Remove denali_reset_banks()
      * Remove ->dev_ready() hook
      * Include <linux/bits.h> instead of <linux/bitops.h>
      * Changes to comply with the above fixes/cleanup done in the core.
   - FSMC:
      * Add an SPDX tag to replace the license text
      * Make conversion from chip to fsmc consistent
      * Fix unchecked return value in fsmc_read_page_hwecc
      * Changes to comply with the above fixes/cleanup done in the core.
   - Marvell:
      * Prevent timeouts on a loaded machine (fix)
      * Changes to comply with the above fixes/cleanup done in the core.
   - OMAP2:
      * Pass the parent of pdev to dma_request_chan() (fix)
   - R852:
      * Use generic DMA API
   - sh_flctl:
      * Convert to SPDX identifiers
   - Sunxi:
      * Write pageprog related opcodes to the right register: WCMD_SET (fix)
   - Tegra:
      * Stop implementing ->select_chip()
   - VF610:
      * Add an SPDX tag to replace the license text
      * Changes to comply with the above fixes/cleanup done in the core.
   - Various trivial/spelling/coding style fixes.

  SPI-NAND drivers changes:
   - Remove the depreacated mt29f_spinand driver from staging.
   - Add support for:
      * Toshiba TC58CVG2S0H
      * GigaDevice GD5FxGQ4xA
      * Winbond W25N01GV

  JFFS2 changes:
   - Fix a lockdep issue

  MTD changes:
   - Rework the physmap driver to merge gpio-addr-flash and physmap_of
     in it
   - Add a new compatible for RedBoot partitions
   - Make sub-partitions RW if the parent partition was RO because of a
     mis-alignment
   - Add pinctrl support to the
   - Addition of /* fall-through */ comments where appropriate
   - Various minor fixes and cleanups

  Other changes:
