Could you give me some advice? You should set up the supplies to point to whatever regulator is supplying the power. If there are supplies on the board which are generated using fixed voltage regulators then you should register those using the fixed regulator driver. Recent kernels are more tolerant of missing supplies but it's still better to be explicit if you can be. -------------- next part -------------- A non-text attachment was scrubbed...
