I apologize for this mistake. I just forgot this after removing
default value in the Kconfig.

At now, we only maintain the dts related change, but not the driver 
code. The driver code is usually applied by the subsystem maintainer. 
This is why you only see the clk changes in the linux-next.

As you see, the driver code applied to the clk/for-next. That is the
tree used to push.
