Pull mtd updates from Miquel Raynal:
 "MTD core changes:
   - Fix refcount error in del_mtd_device()
   - Fix possible resource leak in init_mtd()
   - Set ROOT_DEV for partitions marked as rootfs in DT
   - Describe marking rootfs partitions in the bindings
   - Fix device name leak when register device fails in add_mtd_device()
   - Try to find OF node for every MTD partition
   - simplify (a bit) code find partition-matching dynamic OF node

  MTD driver changes:
   - pxa2xx-flash maps: fix memory leak in probe
   - BCM parser: refer to ARCH_BCMBCA instead of ARCH_BCM4908
   - lpddr2_nvm: Fix possible null-ptr-deref
   - inftlcore: fix repeated words in comments
   - lart: remove driver
   - tplink:
      - Add TP-Link SafeLoader partitions table parser and bindings
      - Describe TP-Link SafeLoader parser
      - Describe TP-Link SafeLoader dynamic subpartitions
   - mtdoops:
      - Panic caused mtdoops to call mtdoops_erase function immediately
      - Add mtdoops_erase function and move mtdoops_inc_counter after it
      - Change printk() to counterpart pr_ functions

  MTD binding cleanup:
   - Fixed-partitions: Fix 'sercomm,scpart-id' schema
   - Standardize the style in the examples
   - Drop object types when referencing other files
   - Argue in favor of keeping additionalProperties set to true
   - NVMEM-cells:
      - Inherit from MTD partitions
      - Drop range property from example
   - Partitions:
      - Change qcom,smem-part partition type
      - Constrain the list of parsers
   - Physmap: Reuse the generic definitions
   - SPI-NOR: Drop common properties
   - Sunxi-nand: Add an example to validate the bindings
   - Onenand: Mention the expected node name
   - Ingenic: Mark partitions in the controller node as deprecated
   - NAND:
      - Standardize the child node name
      - Drop common properties already defined in generic files
      - nand-chip.yaml should reference mtd.yaml
   - Remove useless file about partitions
   - Clarify all partition subnodes

  SPI NOR core changes:
   - Add support for flash reset using the dt reset-gpios property.
   - Update hwcaps.mask to include 8D-8D-8D read and page program ops
     when xSPI profile 1.0 table is defined.
   - Bypass zero erase size in spi_nor_find_best_erase_type().
   - Fix select_uniform_erase to skip 0 erase size
   - Add generic flash driver. If a flash is not found in the flash_info
     array, fall back to the generic flash driver which is described
     solely by the flash's SFDP tables.
   - Fix the number of bytes for the dummy cycles in
     spi_nor_spimem_check_readop().
   - Introduce SPI_NOR_QUAD_PP flag, as PP_1_1_4 is not SFDP
     discoverable.

  SPI NOR manufacturer drivers changes:
   - Spansion:
      - use PARSE_SFDP for s28hs512t,
      - add support for s28hl512t, s28hl01gt, and s28hs01gt.
   - Gigadevice: Replace default_init() with post_bfpt() for gd25q256.
   - Micron - ST: Enable locking for mt25qu256a.
   - Winbond: Add support for W25Q512NW-IQ.
   - ISSI: Use PARSE_SFDP and SPI_NOR_QUAD_PP.

  Raw NAND core changes:
   - Drop obsolete dependencies on COMPILE_TEST
   - MAINTAINERS: rectify entry for MESON NAND controller bindings
   - Drop EXPORT_SYMBOL_GPL for nanddev_erase()

  Raw NAND driver changes:
   - marvell: Enable NFC/DEVBUS arbiter
   - gpmi: Use pm_runtime_resume_and_get instead of pm_runtime_get_sync
   - mpc5121: Replace NO_IRQ by 0
   - lpc32xx_{slc,mlc}:
      - Switch to using pm_ptr()
      - Switch to using gpiod API
   - lpc32xx_mlc: Switch to using pm_ptr()
   - cadence: Support 64-bit slave dma interface
   - rockchip: Describe rk3128-nfc in the bindings
   - brcmnand: Update interrupts description in the bindings

  SPI-NAND driver changes:
   - winbond:
      - Add Winbond W25N02KV flash support
      - Fix flash identification"
