Can I add your Acked-by on this one, when I send the rebased patch set? Thanks,

Yes, I saw this series which depends on Daniel Mack's work. It looks good. You can add Acked-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

Pass an optional device_node pointer in the platform data, which in turn will be put into a mtd_part_parser_data. This way, code that sets up the platform devices can pass along the node from DT so that the partitions can be parsed. For non-DT boards, this change has no effect.
