It would be interesting to know what the authors original motivation implementing this feature was. Reading the email of the original patchset indicates that there are platforms where only TCF is supported:

However, I don't know which platform that would be. Also, it seems that Chao Fu's email is not valid anymore.
It's not clear to me if the above means that this is due to hardware differences or due to tuning for the platform.
