Just follow Linux binding instead of create new one. Why a nack? This comes from the Linux kernel mainline code I submited. I am not creating anything new. This technically should have come in with the original port of the driver I pushed to the Linux kernel. But I defer to the Tom for the resolution.

I know what you are referring to now. I did not use ti,tx-internal-delay and ti,rx-internal-delay. I used ti,tx-int-delay and ti,rx-int-delay which is wrong.
