Merge tag 'nand/for-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux into mtd/next
NAND core changes: - use longest matching pattern in ->exec_op() default parser - export NAND operation tracer - add flag to indicate panic_write in MTD - use kzalloc() instead of kmalloc() and memset() Raw NAND controller drivers changes: - brcmnand: * fix BCH ECC layout for large page NAND parts * fallback to detected ecc-strength, ecc-step-size * when oops in progress use pio and interrupt polling * code refactor code to introduce helper functions * add support for v7.3 controller - FSMC: * use nand_op_trace for operation tracing - GPMI: * move all driver code into single file * various cleanups (including dmaengine changes) * use runtime PM to manage clocks * implement exec_op - MTK: * correct low level time calculation of r/w cycle * improve data sampling timing for read cycle * add validity check for CE# pin setting * fix wrongly assigned OOB buffer pointer issue * re-license MTK NAND driver as Dual MIT/GPL - STM32: * manage the get_irq error case * increase DMA completion timeouts Raw NAND chips drivers changes: - Macronix: add read-retry support Onenand driver changes: - add support for 8Gb datasize chips - avoid fall-through warnings SPI-NAND changes: - define macros for page-read ops with three-byte addresses - add support for two-byte device IDs and then for GigaDevice GD5F1GQ4UFxxG - add initial support for Paragon PN26G0xA - handle the case where the last page read has bitflips
