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 Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
