Clocks are introduced towards the tail of the dts -> this has a problem
associated with it -> device nodes should be able to reference phandle
like:
devicex {
clocks = <&sys_ck>;
}
Since all the devices on ocp and cpu0 node appears above the definition
they fail to catch the phandle. instead, moving the clocks node as high
in the tree as possible resolves this: something like:
diff --git a/arch/arm/boot/dts/omap3.dtsi b/arch/arm/boot/dts/omap3.dtsi

What do you think of the change? applies for all clock nodes in other
dtsi as well - I will mark them as I find them.
Further,

dont need to state the above two -> already done in omap3.dtsi.
