Hi Bryan,
Thanks for the set.

This seems redundant.

Could you instead use the frequency already set, using assigned-clock* in
the example?

Almost certainly yes. Yeah, I do that so. --- bod

Not sure what do you mean here. Drop the clock-names and clock-frequency. Both are redundant. You should almost never have a clock-frequency in your device bindings. Best regards, Krzysztof
