Hello Linus,

A bit in advance, here is the MTD PR for the opening merge window for v6.8-rc1.

Thanks,
Miquèl

Merge tag 'nand/for-6.8' into mtd/next (2023-12-22 12:45:52 +0100)

----------------------------------------------------------------
* MTD

Apart from preventing the mtdblk to run on top of ftl or ubiblk (which may cause security issues and has no meaning anyway), there are a few misc fixes.

* Raw NAND

Two meaningful changes this time. The conversion of the brcmnand driver to the ->exec_op() API, this series brought additional changes to the core in order to help controller drivers to handle themselves the WP pin during destructive operations when relevant.

There is also a series bringing important fixes to the sequential read feature.

As always, there is as well a whole bunch of miscellaneous W=1 fixes, together with a few runtime fixes (double free, timeout value, OOB layout, missing register initialization) and the usual load of remove callbacks turned into void (which led to switch the txx9ndfmc driver to use module_platform_driver()).

* SPI NOR

SPI NOR comes with die erase support for multi die flashes, with new octal protocols (1-1-8 and 1-8-8) parsed from SFDP and with an updated documentation about what the contributors shall consider when proposing flash additions or updates.

Michael Walle stepped out from the reviewer role to maintainer.
