Clocks on Barebox

[andreas.willig at rafi.de]

Hi Sascha,
I'm currently on the next branch, but i did not see changes at this point since master or stable release. Like issued earlier the clock table enumeration is empty. Is there a specific compatible attribute required? 
 

Mit freundlichen Grüßen aus Berg/ With kind regards

I have no idea currently. You are doing nothing obviously wrong.

These are removed because they come from the OF clock providers now. For
this you need COMMON_CLK_OF_PROVIDER enabled, but this should be
selected by the imx6 support automatically though. Let me test this on
some hardware here. What barebox version do you use? master, next, or
the latest release?

Sascha
