Cool. Just a word of comment to my own words ;-) The "bail out" case was a bad idea - the non-DT use cases more likely than not will have no clock name defined. So, to maintain backward compatibility, the driver will still have to work when no named clock is available. I think the simplest way to do that is to check if "hclk" is available, and use it if it is (setting the clksel accordingly). Otherwise - proceed as it was the case previously.
