Jian,

When replying to the v1 of your clk_ao patchset : 
https://patchwork.kernel.org/patch/10562563/#22177627

I have explained that I would like to stop taking clock (such as xtal) from
nowhere. Clocks (even the xtal) should be properly claimed through DT.
I have specifically asked this to be taken into account for the EE controller.

If you need an exemple on how to get the input clock from DT to your
controller, please have look at the axg audio clock controller.
