    Subject[PATCH 2/2] arm64: dts: freescale: sl28: add variant 1
    Date
    There is a new variant 1 of this board available. It features up to four
    SerDes lanes for customer use. Add a new device tree which features just
    the basic peripherals. A customer will then have to modify or append to
    this device tree.
