Merge tag 'mtd/for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux

Pull mtd updates from
 "Core MTD changes:
   - otp:
      - Put factory OTP/NVRAM into the entropy pool
      - Clean up on error in mtd_otp_nvmem_add()

  MTD devices changes:
   - sm_ftl: Fix typos in comments
   - Use SPDX license headers
   - pismo: Switch back to use i2c_driver's .probe()
   - mtdpart: Drop useless LIST_HEAD
   - st_spi_fsm: Use the devm_clk_get_enabled() helper function

  DT binding changes:
   - partitions:
      - Include TP-Link SafeLoader in allowed list
      - Add missing type for "linux,rootfs"
   - Extend the nand node names filter
   - Create a file for raw NAND chip properties
   - Mark nand-ecc-placement deprecated
   - Describe nand-ecc-mode
   - Prevent NAND chip unevaluated properties in all NAND bindings with
     a NAND chip reference.
   - Qcom: Fix a property position
   - Marvell: Convert to YAML DT schema

  Raw NAND chip drivers changes:
   - Macronix: OTP access for MX30LFxG18AC
   - Add basic Sandisk manufacturer ops
   - Add support for Sandisk SDTNQGAMA

  Raw NAND controller driver changes:
   - Meson:
      - Replace integer consts with proper defines
      - Allow waiting w/o wired ready/busy pin
      - Check buffer length validity
      - Fix unaligned DMA buffers handling
      - dt-bindings: Fix 'nand-rb' property
   - Arasan: Revert "mtd: rawnand: arasan: Prevent an unsupported
     configuration" as this limitation is no longer true thanks to the
     recent efforts in improving the clocks support in this driver

  SPI-NAND changes:
   - Gigadevice: add support for GD5F2GQ5xExxH
   - Macronix: Add support for serial NAND flashes"
