Merge tag 'mtd/for-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux
Pull mtd updates from Miquel Raynal:
"Core MTD changes:
- dt-bindings: Drop unneeded quotes
- mtdblock: Tolerate corrected bit-flips
- Use of_property_read_bool() for boolean properties
- Avoid magic values
- Avoid printing error messages on probe deferrals
- Prepare mtd_otp_nvmem_add() to handle -EPROBE_DEFER
- Fix error path for nvmem provider
- Fix nvmem error reporting
- Provide unique name for nvmem device
MTD device changes:
- lpddr_cmds: Remove unused words variable
- bcm63xxpart: Remove MODULE_LICENSE in non-modules
SPI NOR core changes:
- Introduce Read While Write support for flashes featuring several
banks
- Set the 4-Byte Address Mode method based on SFDP data
- Allow post_sfdp hook to return errors
- Parse SCCR MC table and introduce support for multi-chip devices
SPI NOR manufacturer drivers changes:
- macronix: Add support for mx25uw51245g with RWW
- spansion:
- Determine current address mode at runtime as it can be changed
in a non-volatile way and differ from factory defaults or from
what SFDP advertises.
- Enable JFFS2 write buffer mode for few ECC'd NOR flashes:
S25FS256T, s25hx and s28hx
- Add support for s25hl02gt and s25hs02gt
Raw NAND core changes:
- Convert to platform remove callback returning void
- Fix spelling mistake waifunc() -> waitfunc()
Raw NAND controller driver changes:
- imx: Remove unused is_imx51_nfc and imx53_nfc functions
- omap2: Drop obsolete dependency on COMPILE_TEST
- orion: Use devm_platform_ioremap_resource()
- qcom:
- Use of_property_present() for testing DT property presence
- Use devm_platform_get_and_ioremap_resource()
- stm32_fmc2: Depends on ARCH_STM32 instead of MACH_STM32MP157
- tmio: Remove reference to config MTD_NAND_TMIO in the parsers
Raw NAND manufacturer driver changes:
- hynix: Fix up bit 0 of sdr_timing_mode
SPI-NAND changes:
- Add support for ESMT F50x1G41LB"
