Can you resend this series on top of linux_next?
Some of the missing items I seen
1. Of_node not populated in omap_nand_platform_data structure.
2. Remove platform device creation from hwmod as GPMC DT is populating.
Currently GPMC device creaing from DT & HWMOD.
Also can you address how this patch series depends on
mtd: nand: OMAP: ELM error correction support for BCH ecc
Thanks
