    You want someone to probe the SCK frequency? I expect that if frequency
    switching works on LS1028A, and the lx2160a_flexspi_divs table is
    correct (which, based on the documentation for FlexSPICR1[FlexSPI_CLK_DIV],
    it is), then it would work on LX2160A too?
    Is there a simple test that can be made in order to trivially determine
    whether the frequencies are correct?
