Just wondering, can we completely deorbit ti,bit-shift if we used #address-cells = <2>; in those cases? I wait a bit with further txt->yaml conversions until this is settled. Regards, Andreas

And add a comment saying it is only needed for the remaining unconnected clocks. Eventually we can move all the component clocks under clksel clocks, or the related clock such as the dpll clock for the clkdcoldo clocks. Regards, Tony

Oh and yes, using #clock-cells = <2> would be nice eventually :) I think the clkcel binding already supports that. But that still leaves the issue of unconnected composite clocks.. I'm pretty sure they all have some real parent like clksel for dpll though. If you had some good idea in mind for the #address-cells = <2> for the remaining unconnected composite clocks maybe clarify it a bit. Regards, Tony

Yeah sure nothing stopping us from doing that too if it helps :) Regards, Tony
Hi all, This series updates the clksel clocks to use the standard reg property instead of ti,bit-shift. I'd like to apply these before we make further use of the clksel clocks to reduce the dtb check warnings.
