Pull MTD updates from Richard Weinberger:
 "MTD core changes:

   - tests:
      - Remove redundant assignment to err
      - Fix error return code in mtd_oobtest_init()
   - Add OTP NVMEM provider support
   - Allow specifying of_node
   - Convert sysfs sprintf/snprintf family to sysfs_emit

  Bindings changes:

   - spi-nor: add otp property
   - Add OTP bindings
   - add YAML schema for the generic MTD bindings
   - Add brcm,trx-magic

  MTD device drivers changes:
   - Add support for microchip 48l640 EERAM
   - Remove superfluous "break"
   - sm_ftl:
      - Fix alignment of block comment
   - nftl:
      - Return -ENOMEM when kmalloc failed
   - nftlcore:
      - Remove set but rewrite variables
   - phram:
      - Fix error return code in phram_setup()

  MTD parsers changes:
   - Qcom:
      - Fix leaking of partition name

      - Allow to specify brcm, trx-magic in DT

  Raw NAND core:
   - Allow SDR timings to be nacked
   - Bring support for NV-DDR timings which involved a number of small
     preparation changes to bring new helpers, properly introduce NV-DDR
     structures, fill them, differenciate them and pick the best timing
     set.
   - Add the necessary infrastructure to parse the new gpio-cs property
     which aims at enlarging the number of available CS when a hardware
     controller is too constrained.
   - Update dead URL
   - Silence static checker warning in nand_setup_interface()
   - BBT:
      - Fix corner case in bad block table handling
   - onfi:
      - Use more recent ONFI specification wording
      - Use the BIT() macro when possible

  Raw NAND controller drivers:
   - Atmel:
      - Ensure the data interface is supported.
   - Arasan:
      - Finer grain NV-DDR configuration
      - Rename the data interface register
      - Use the right DMA mask
      - Leverage additional GPIO CS
      - Ensure proper configuration for the asserted target
      - Add support for the NV-DDR interface
      - Fix a macro parameter
   - brcmnand:
      - Convert bindings to json-schema
   - OMAP:
      - Various fixes and style improvements
      - Add larger page NAND chips support
   - PL35X:
      - New driver
   - QCOM:
      - Avoid writing to obsolete register
      - Delete an unneeded bool conversion
      - Allow override of partition parser
   - Marvell:
      - Minor documentation correction
      - Add missing clk_disable_unprepare() on error in
        marvell_nfc_resume()
   - R852:
      - Use DEVICE_ATTR_RO() helper macro
   - MTK:
      - Remove redundant dev_err call in mtk_ecc_probe()
   - HISI504:
      - Remove redundant dev_err call in probe

  SPI-NAND core:
   - Light reorganisation for the introduction of a core resume handler
   - Fix double counting of ECC stats

  SPI-NAND manufacturer drivers:
   - Macronix:
      - Add support for serial NAND flash

  SPI NOR core changes:
   - Ability to dump SFDP tables via sysfs
   - Support for erasing OTP regions on Winbond and similar flashes
   - Few API doc updates and fixes
   - Locking support for MX25L12805D

  SPI NOR controller drivers changes:
