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.
