Why can the kernel not decide this?
It can.

if without this property, the mclk is generated from SOC.
Huh? What exact property do you actually are about here?
This should just be omitted - based on the previous posting it's saying if this is a fixed or variable rate clock.
- wlf,mclk-freq: mclk's frequency
If you expect mclk, you should be able to query this from it. You don't need a separate property.
Unless this is a frequency to set it to? If so, why can the kernel not choose this?
Yes, quite - and even if it needs to be set explicitly the clock API generic bindings should be able to support this (I *think* that is due to go in during the next merge window but iddn't check yet).
