Merge tag 'nand/for-5.18' into mtd/next

Raw NAND core changes:
* Rework of_get_nand_bus_width()
* Remove of_get_nand_on_flash_bbt() wrapper
* Protect access to rawnand devices while in suspend
* bindings: Document the wp-gpios property

Rax NAND controller driver changes:
* atmel: Fix refcount issue in atmel_nand_controller_init
* nandsim:
  - Add NS_PAGE_BYTE_SHIFT macro to replace the repeat pattern
  - Merge repeat codes in ns_switch_state
  - Replace overflow check with kzalloc to single kcalloc
* rockchip: Fix platform_get_irq.cocci warning
* stm32_fmc2: Add NAND Write Protect support
* pl353: Set the nand chip node as the flash node
* brcmnand: Fix sparse warnings in bcma_nand
* omap_elm: Remove redundant variable 'errors'
* gpmi:
  - Support fast edo timings for mx28
  - Validate controller clock rate
  - Fix controller timings setting
* brcmnand:
  - Add BCMA shim
  - BCMA controller uses command shift of 0
  - Allow platform data instantation
  - Add platform data structure for BCMA
  - Allow working without interrupts
  - Move OF operations out of brcmnand_init_cs()
  - Avoid pdev in brcmnand_init_cs()
  - Allow SoC to provide I/O operations
  - Assign soc as early as possible

Onenand changes:
* Check for error irq
