Merge tag 'mtd/for-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux

Pull MTD updates from Miquel Raynal:
 "MTD core changes:

   - mtdchar: Prevent unbounded allocation in MEMWRITE ioctl

   - gen_probe: Use bitmap_zalloc() when applicable

   - Introduce an expert mode for forensics and debugging purposes

   - Clear out unregistered devices a bit more

   - Provide unique name for nvmem device

   - Remove unused header file <linux/mtd/latch-addr-flash.h>

   - Fixed breaking list in __mtd_del_partition.

  MTD device changes:

   - Warn about failure to unregister mtd device in sst25l, mchp48l640,
     mchp23k256, and dataflash drivers.

  Raw NAND core changes:

   - Export nand_read_page_hwecc_oob_first()

  GPMC memory controller for OMAP2 NAND controller changes:

   - Add support for AM64 SoC and allow build on K3 platforms

   - Use a compatible match table when checking for NAND controller

   - Use platform_get_irq() to get the interrupt

  Raw NAND controller changes:

   - OMAP2 NAND controller:
      - Document the missing 'rb-gpios' DT property
      - Drop unused variable
      - Fix force_8bit flag behaviour for DMA mode
      - Move to exec_op interface
      - Use platform_get_irq() to get the interrupt

   - Renesas:
      - Add new NAND controller driver with its bindings and MAINTAINERS entry

   - Onenand:
      - Remove redundant variable ooblen

   - MPC5121:
      - Remove unused variable in ads5121_select_chip()

   - GPMI:
      - Add ERR007117 protection for nfc_apply_timings
      - Remove explicit default gpmi clock setting for i.MX6
      - Use platform_get_irq_byname() to get the interrupt
      - Remove unneeded variable

   - Ingenic:
      - JZ4740 needs 'oob_first' read page function

   - Davinci:
      - Rewrite function description
      - Avoid duplicated page read
      - Don't calculate ECC when reading page

  SPI NOR core changes:

   - Add Pratyush as SPI NOR co-maintainer.

   - Flash parameters initialization was done in a spaghetti way. Clean
     flash parameters initialization.

   - Rework the flash_info flags and clarify where one should be used.

   - Initialize all flash parameters based on JESD216 SFDP where
     possible. Flash parameters and settings that are SFDP discoverable
     should not be duplicated via flash_info flags at flash declaration.

   - Remove debugfs entries that duplicate sysfs entries.

  SPI NOR manufacturer driver changes:

   - Use late_init() hook in various drivers to make it clear that those
     flash parameters are either not declared in the JESD216 SFDP
     standard, or the SFDP tables which define those flash parameters
     are not defined by the flash.

   - Fix mtd size for s3an flashes.

   - Write 2 bytes when disabling Octal DTR mode: 1 byte long
     transactions are not allowed in 8D-8D-8D mode.

  Hyperbus changes:

   - Couple of fixes in Renesas hyperbus rpc-if driver to avoid crash on
     module remove and for missing check for error value in probe"
