That is for Mike / Stephen to answer. Implementing something like this 
sounds trivial, I could just hook up the ti_clk_get being called here. 
However, any attempted changes to the clkdev implementation have been 
shot down so far, thus I did this.

The problem is still the clocks which are just referred via a name only, 
not via a DT node.
