Merge tag 'mtd/for-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux
Pull mtd updates from Miquel Raynal:
"MTD changes:
- Apart from a binding conversion to yaml, only minor changes/small
fixes have been merged.
Raw NAND changes:
- Minor fixes for various controller drivers like DMA mapping checks,
better timing derivations or bitflip statistics.
- some Hynix NAND flashes were not supporting read-retries, so don't
even try to do it
SPI NAND changes:
- In order to support high-speed modes, certain chips need extra
configuration like adding more dummy cycles. This is now possible,
especially on Winbond chips.
- Aside from that, Gigadevice gets support for a new chip (GD5F1GM9).
SPI NOR changes:
- A notable changes is the fix for exiting 4-byte addressing on
Infineon SEMPER flashes. These flashes do not support the standard
EX4B opcode (E9h), and use a vendor-specific opcode (B8h) instead.
- There is also a fix for unlocking flashes that are write-protected
at power-on. This was caused by using an uninitialized mtd_info in
spi_nor_try_unlock_all()"
