Parses OMAP clock data from DT and registers those clocks with the clock
framework.  dt_omap_clk_init must be called early during boot for timer
initialization so it is exported and called from the existing clock code
instead of probing like a real driver. Based on initial work done by
Mike Turquette.

Minor suggestion - should we just start drivers/clk/ti/ instead of clk/omap?

AM335x/DRA7 are not "strictly OMAP".. might also allow for some reuse 
for other TI platforms..

should it? :)

drivers/clk/clk-fixed-rate.c seems to already do this with 
CLK_OF_DECLARE, or am I mistaken? and so on?

Might be good to have kernel doc to explain the init requirement as 
documented in commit message.

just doing of_clk_init(NULL); should do the job, no? that could even be 
a static inline OR introduced in board_generic without additional headers?

would you like to match licensing to that of the C file?

Not sure, this idea has been bounced around a bit. samsung has its own 
directory under drivers/clk/ so maybe. I can change this if there is a 
strong wish for this.

Maybe remove the PRCM part. We have some clocks behind i2c for example, 
and we might want to add support for them here.

Not 100% sure about the answer to this, the current implementation works 
though so we could potentially drop this comment. :)

Yeah, I am lacking docs once again.

I don't think that works, as we have special clock node types we want to 
support (the TI specific types, and we want to override the default 
behavior of some.)

Ok, copy paste bug #2 for this. Initial version was worse than this though.

just my 2 cents - if we use drivers/clk/ti, we can then move required 
stuff from arch/arm/mach-davinci or arch/arm/mach-keystone to a ti 
generic location allowing us to reuse things as needed.

I think we can actually drop this file in it's entirety if we stick with 
of_clk_init(NULL) and depend solely of CLK_OF_DECLARE from relevant drivers.

Yeah, I'll do this and drop the file.
