    Subject[PATCH v3 8/9] arm64: dts: ls1028a: fix FlexSPI clock
    Date
    Now that we have a proper driver for the FlexSPI interface use it. This
    will fix SCK frequency switching on Layerscape SoCs.

    This was tested on the Kontron sl28 board.

    Changes since v2:
    - use device tree constants for clockgen
    - also use &fspi_clk for fspi_en clock

    Changes since v1:
    - none
