Merge tag 'mtd/for-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux

Pull MTD updates from Miquel Raynal:
 "MTD:

   - Simon Glass wanted to support binman's output properties in order
     to check their validity using the binding checks and proposed
     changes with the missing properties as well as a binman compatible.

   - Krzysztof Kozlowski on his side shared a new yaml for describing
     Samsung's OneNAND interface.

   - The interface with NVMEM has also been slightly improved/fixed,
     especially now that OTP are also supported in the NAND subsystem.

   - Along with these changes, small cleanups have also been contributed
     around ID tables, structure sizes, arithmetic checks and comments.

  Raw NAND subsystem:

   - Two small fixes, one in the Hynix vendor code for properly
     returning an error which might have been ignored and another in the
     Davinci driver to properly synchronize the controller with the gpio
     domain.

  SPI NOR subsystem:

   - SPI NOR now uses div_u64() instead of div64_u64() in places where
     the divisor is 32 bits. Many 32 bit architectures can optimize this
     variant better than a full 64 bit divide"
