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?
