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
