I have resent all of the clk patches (including all of the ones I listed as
dependencies in addition to the three remaining in this series) under the
cover "clk: davinci: outstanding fixes".

I also found that we need to add power-domains properties to the PWM nodes
in "ARM: dts: da850: Add clocks". I probably should just take your advice
and just globally added them even if they are not documented for some types
ofnodes.
