[Lu Yangbo-B47093] Hi York, do you mean check the clock name or compatible to make sure it's sysclk and then fix it?
Scott's patch added coreclock node also with compatible 'fixed-clock'.
https://patchwork.kernel.org/patch/9536515/

If we check clock name, I found most names with 'fixed-clock' compatible are 'sysclk', but some are not.
fsl-ls1012a-frdm.dts:
        sys_mclk: clock-mclk {
                compatible = "fixed-clock";
                #clock-cells = <0>;
                clock-frequency = <25000000>;
        };

fsl-ls1012a-qds.dts:
        sys_mclk: clock-mclk {
                compatible = "fixed-clock";
                #clock-cells = <0>;
                clock-frequency = <24576000>;
        };

Do you have any suggestion?
Thanks.
