Ref: 
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9f5dc91b691cf296c49aedf0a671fd659a70f737 
and the fact that OSWR and OFF both have been descoped in production 
silicon, is again the reason why TI has not posted these preproduction 
experimentation patches upstream.

NAK once again. Sorry.

PS: deleting Santosh's old TI ID which should unfortunately be 
bouncing now.
