For this to work.
Someone has to implement this for MSM72XX, which is completely different than what's in the TI phones.
I am not sure if that code is even in the kernel (GPU clock). I don't recall seeing it but I haven't really looked at the kernel all that much.
It's all in the board files if it's anywhere.
