Merge tag 'nand/for-4.12' of github.com:linux-nand/linux into MTD
From Boris:
"""
This pull request contains:
- some minor fixes/improvements on existing drivers (fsmc, gpio, ifc,
davinci, brcmnand, omap)
- a huge cleanup/rework of the denali driver accompanied with core
fixes/improvements to simplify the driver code
- a complete rewrite of the atmel driver to support new DT bindings
make future evolution easier
- the addition of per-vendor detection/initialization steps to avoid
extending the nand_ids table with more extended-id entries
