Using an undocumented feature in a chip is very dangerous. Minor changes to the fab, even though the 
chip has the same number may change or remove that undocumented feature that the phones now rely on.

If this is going to be adopted in builds, then someone at OM needs to get TI to officially support 
that feature so that it does not disappear later.
