    Subject[PATCH v1 0/2] Implement SoC bus support for Vybrid
    Date
    Hello,

    This patchset implements SoC bus support for Freescale Vybrid platform,
    implementing the following
    https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-devices-soc

    The RFC version can be found here
    https://lkml.org/lkml/2015/5/11/13

    Currently the required information is more or less read across the whole
    SoC, but I guess we cannot change that since these are the locations
    with the required information.

    There seem to be three options for the revision field:
    - ROM revision (see https://community.freescale.com/docs/DOC-94802)
    - ANADIG revision (ANADIG_DIGIPROC, as used for the i.MX SoC's)
    - OCOTP revision

    Some numbers:

    Colibri VF61 1.1A (2N02G)
    - 0x00000013
    - 0x00610000
    - 0x01000000
    - 0x410000c8

    Colibri VF61 V1.0B (1N02G)
    - 0x00000011
    - 0x00610000
    - 0x01000000
    - 0x410000c8

    Colibri VF61 V1.0A (which is actually a VF600 SoC, no L2 cache, since
    that was the only one we could buy back then, 1N02G printed on it)
    - 0x00000011
    - 0x00610000
    - 0x01000000
    - none...

    Colibri VF50 V1.0A (1N02G)
    - 0x00000011
    - 0x00610000
    - 0x01000000
    - none...

    Vybrid Tower Rev J (1N02G)
    - 0x00000011
    - 0x00610000
    - 0x01000000
    - 0x410000c8

    The ROM revision differs the most, so we would like to go with the
    revision information from the ROM register 0x80.

    Changes since RFC:
    - Use a DT entry for the ROM area while specifying it as syscon.

    Thanks & Regards,
    Sanchayan Maity.
