Hi Michael,

The info on the email you referenced is kind of obsolete, TI SoCs are 
calling of_clk_init() during boot now, and thus external clock nodes 
should be registered fine also. Maybe you can provide the actual DTS 
patch you are trying out so we can help better...? Are you seeing any 
boot time error / warning prints for your new clock?
