Instead, add a fixed div-2 clock to the DTS file (I guess in the SoC file) to divide the crystal frequency into the rate you want (19.2 MHz in this case). > + clk-output-names = "bi_tcxo", "lnbb_clk2", > + "lnbb_clk3"; We don't need this either. -- To unsubscribe from this list: send the line "unsubscribe linux-clk" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
