+ description: A subnode with three clock cells for externally routed clocks,
+ output clocks. These are two PRCMU-internal clocks that can be divided and
+ muxed out on the pads of the DB8500 SoC. The first cell indicates which
+ output clock we are using, possible values are 0 (CLKOUT1) and 1 (CLKOUT2).
+ The second cell indicates which clock we want to use as source, possible
+ values are 0 thru 7, see the defines for the different source clocks.
+ The third cell is a divider, legal values are 1 thru 63.
