Can you explain a bit more why this is needed? I looked it over a few times, and I'm not sure what it does differently from clk_of_xlate_default.
If memory serves, the indices were starting at 0 instead of 1. To match what Lniux does we I need to switch the index to be 1,2,3,4 instead of 0,1,2,3 since there is an OUT0. It's been a while since I did this, so I don't fully remember. If you have good success removing it and using the clk_of_xlate_default, I'm willing to test it to make sure it doesn't break my board so we can remove it.
