    Subject[PATCH 16/20] ARM: dts: aspeed: Add Witherspoon BMC machine
    Date
    The Witherspoon BMC is an ASPEED ast2500 based BMC that is part of an
    OpenPower Power9 server.

    This adds the device tree description for most upstream components. It
    is a squashed commit from the OpenBMC kernel tree.
