Merge tag 'nand/for-6.4' into mtd/next

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
