Merge tag 'mtd/for-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux

Pull mtd updates from Miquel Raynal:
 "MTD core changes:
   - Spelling
   - http to https updates

  NAND core changes:
   - Drop useless 'depends on' in Kconfig
   - Add an extra level in the Kconfig hierarchy
   - Trivial spellings
   - Dynamic allocation of the interface configurations
   - Dropping the default ONFI timing mode
   - Various cleanup (types, structures, naming, comments)
   - Hide the chip->data_interface indirection
   - Add the generic rb-gpios property
   - Add the ->choose_interface_config() hook
   - Introduce nand_choose_best_sdr_timings()
   - Use default values for tPROG_max and tBERS_max
   - Avoid redefining tR_max and tCCS_min
   - Add a helper to find the closest ONFI mode
   - bcm63xx MTD parsers: simplify CFE detection

  Raw NAND controller drivers changes:
   - fsl-upm: Deprecation of specific DT properties
   - fsl_upm: Driver rework and cleanup in favor of ->exec_op()
   - Ingenic: Cleanup ARRAY_SIZE() vs sizeof() use
   - brcmnand: ECC error handling on EDU transfers
   - brcmnand: Don't default to EDU transfers
   - qcom: Set BAM mode only if not set already
   - qcom: Avoid write to unavailable register
   - gpio: Driver rework in favor of ->exec_op()
   - tango: ->exec_op() conversion
   - mtk: ->exec_op() conversion

  Raw NAND chip drivers changes:
   - toshiba: Implement ->choose_interface_config() for TH58NVG2S3HBAI4,
     TC58NVG0S3E, and TC58TEG5DCLTA00
   - hynix: Implement ->choose_interface_config() for H27UCG8T2ATR-BC

  SPI NOR core changes:
   - Disable Quad Mode in spi_nor_restore().
   - Don't abort BFPT parsing when QER reserved value is used.
   - Add support/update capabilities for few flashes.
   - Drop s70fl01gs flash: it does not support RDSR(05h) which is
     critical for erase/write.
   - Merge the SPIMEM DTR bits in spi-nor/next to avoid conflicts during
     the release cycle.

  SPI NOR controller drivers changes:
   - Move the cadence-quadspi driver to spi-mem. The series was taken
     through the SPI tree. Merge it also in spi-nor/next to avoid
     conflicts during the release cycle.
   - intel-spi:
      - Add new PCI IDs.
      - Ignore the Write Disable command, the controller doesn't support
        it.
      - Fix performance regression"
