Hello,

This is the MTD PR for 7.2. It is a bit late since I was away for the
past 10 days.

Thanks,
Miquèl

The following changes since commit 7fd2df204f342fc17d1a0bfcd474b24232fb0f32:

  Linux 7.1-rc2 (2026-05-03 14:21:25 -0700)

are available in the Git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux.git tags/mtd/for-7.2

for you to fetch changes up to 49420dfdedd676befaa999b165a76d8d7eec4fab:

  Merge tag 'nand/for-7.2' into mtd/next (2026-06-21 17:05:45 +0200)

----------------------------------------------------------------
NAND changes:

- Extend SPI NAND continuous read to Winbond devices, which requires
  numerous changes in the spi-{mem,nand} layers such as the need for a
  secondary read operation template.

- Continuous reads in general have also been enhanced/fixed for avoiding
  potential issues at probe time and at block boundaries.

SPI NOR changes:

- Big set of cleanups and improvements to the locking support. This
  series contains some cleanups and bug fixes for code and documentation
  around write protection. Then support is added for complement locking,
  which allows finer grained configuration of what is considered locked
  and unlocked. Then complement locking is enabled on a bunch of Winbond
  W25 flashes.

- Fix die erase support on Spansion flashes. Die erase is only supported
  on multi-die flashes, but the die erase opcode was set for all. When
  the opcode is set, it overrides the default chip erase opcode which
  should be used for single-die flashes. Only set the opcode on
  multi-die flashes. Also, the opcode was not set on multi-die s28hx-t
  flashes. Set it so they can use die-erase correctly.

General changes:

- A few drivers and mappings have been removed following SoCs support
  removal.

- And again, there is the usual load of misc improvements and fixes.
