This patch series adds support for NAND flash. The series adds DM support and replaces the existing NAND driver NAND_ATMEL. The drivers are ported from Linux based on the work done by Boris brezillon
If you're going to resubmit, it would be helpful to specify on top of which kernel version your work is based on. This would help to backport fixes or new support in the future.
Please in commit message mention what was changed/dropped for example:
- force poll instead of interrupt - move platform_device to udevice - use of dm_gpio instead of gpiod
