Ok, here is the fix:

--- a/drivers/cpufreq/imx6q-cpufreq.c
+++ b/drivers/cpufreq/imx6q-cpufreq.c
@@ -212,7 +212,7 @@ static int imx6q_cpufreq_probe(struct platform_device *pdev)

        if (of_machine_is_compatible("fsl,imx6ul")) {
                pll2_bus_clk = clk_get(cpu_dev, "pll2_bus");
-               secondary_sel_clk = clk_get(cpu_dev, "secondary_sel");
+               secondary_sel_clk = clk_get(cpu_dev, "secondary_sel_clk");
                if (IS_ERR(pll2_bus_clk) || IS_ERR(secondary_sel_clk)) {
                        dev_err(cpu_dev, "failed to get clocks specific to imx6u

Will send a proper patch.

Thanks
