Yes, I can include this as part of the common clock conversion series.
What I was trying to say is that neither the clock framework not any
other OMAP PM layer today makes any use of this information except for
gate clocks. The only 2 places in the clock framework this is used is
in omap2_dflt_clk_enable()/omap2_dflt_clk_disable() functions, which
are nops for non gate clocks.
So I don;t fully understand what you mean by our current low-level PM
design being based on this assumption that every clock belongs to a
clockdomain.
Did I miss anything else our PM frameworks do with the clock<->clkdm
association? The reason I am asking is because I am doing a lot of 
changes around based on this assumption and would really like to know
if I am missing something.

Rajendra
