Hi,

I'm working on Northstar support (ARM platform with multiple clocks
blocks).

I've just noticed that my clocks don't work anymore after the commit:

It seems that Linux's clock name is derived from DT node. With multiple
clock-controller@ nodes there is a name conflict as seen above.

 From DT perspective I don't think there is anything wrong in having
multiple nodes using the same name prefix.

Could clk subsystem be somehow improved to be more /creative/ at picking
clock names? ;) Would someone be kind to take a look at this, please?
