    Subject[PATCH v3 7/8] cpufreq: ti-cpufreq: Add support for AM3517
    Date
    From: Adam Ford <aford173@gmail.com>

    The AM3517 only lists 600MHz @ 1.2V, but the register values for
    0x4830A204 = 1b86 802f, it seems like am3517 might be a derivative
    of the omap36 which OPPs would be OPP50 (300 MHz) and OPP100
    (600 MHz).

    This patch simply adds the am3517 to the compatible table
    similar to a mix of the omap3430 and omap3430 structure.
