Pull MTD updates from Brian Norris:
 "Summary:
   - Add device tree support for DoC3

   - SPI NOR:
        Refactoring, for better layering between spi-nor.c and its
        driver users (e.g., m25p80.c)

        New flash device support

        Support 6-byte ID strings

   - NAND:
        New NAND driver for Allwinner SoC's (sunxi)

        GPMI NAND: add support for raw (no ECC) access, for testing
        purposes

        Add ATO manufacturer ID

        A few odd driver fixes

   - MTD tests:
        Allow testers to compensate for OOB bitflips in oobtest

        Fix a torturetest regression

   - nandsim: Support longer ID byte strings

  And more"
