[PATCH v2 0/9] NVMEM: Introduce write protection support

[Oleksij Rempel]

This series adds a generic protect op to NVMEM core, enabling
standardized write protection. This makes NVMEM behave more like other
flash interfaces (e.g., CFI block protection), which helps with common
tooling.

Oleksij Rempel (9):
  nvmem: Add 'protect' operation to core framework
  nvmem: rmem: add write and protect support
  commands: nvmem: Add support for creating dynamic rmem devices
  regmap: Add reg_seal operation for hardware protection
  nvmem: regmap: Implement protect operation using regmap_seal
  nvmem: bsec: Implement NVMEM protect via regmap_seal for OTP locking
  nvmem: rmem: generate unic device name
  fs: Report errors for out-of-bounds protect operations
  test: Add pytest suite for NVMEM framework
