I understand the intention of this patch. I was just wondering if all the clocks should be referenced from DT even if that is not strictly needed at the moment. This would make clocks similar to other resources like regulators, gpios, irqs, ... Having the clocks referenced from DT looks cleaner to me. It means I can check the DT file for any resources used by a driver. It also creates some kind of consistency in the kernel. > > Should the clk_get be changed to of_clk_get()/of_clk_get_by_name() in the > > driver?

I'm aware of this. -- Sebastian
