Merge tag 'mtd/for-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux
Pull MTD updates from Miquel Raynal:
"MTD device changes:
- switch platform_driver back to remove()
- misc fixes
SPI-NAND changes:
- a load of fixes to Winbond manufacturer driver
- structure constification
Raw NAND changes:
- improve the power management of the GPMI driver
- Davinci driver clean-ups
- fix leak in the Atmel driver
- fix some typos in the core
SPI NOR changes:
- Introduce byte swap support for 8D-8D-8D mode and a user for it:
macronix.
SPI NOR flashes may swap the bytes on a 16-bit boundary when
configured in Octal DTR mode. For such cases the byte order is
propagated through SPI MEM to the SPI controllers so that the
controllers swap the bytes back at runtime. This avoids breaking
the boot sequence because of the endianness problems that appear
when the bootloaders use 1-1-1 and the kernel uses 8D-8D-8D with
byte swap support. Along with the SPI MEM byte swap support we
queue a patch for the SPI MXIC controller that swaps the bytes back
at runtime"
