davinci_watchdog_reset prototype is moved to time.h as clock.h is
being obsoleted. sleep.S and pm.c is modified to include the new header
file replacements.

With this patch a _third_ copy of PLL definitions is created in kernel
sources. The existing PLL definitions in clock.h inside mach-davinci
should be moved to mach/pll.h and the pll.h you introduced inside
drivers/clk in 5/11 should be removed (this patch should appear before
5/11).
The biggest disadvantage of this approach is inclusion of mach/ includes
in drivers/clk. But duplicating code is definitely not the fix for this.
Anyway, mach/ includes are not uncommon in drivers/clk (they are all
probably suffering from the same issue).
Sekhar,
I have replied to patch 5/11 that also refers to this. The main reason
we are not able to do this cleanly is the code in sleep.c and pm.c. That
is something related to Power management. Could you take a look and see
if you can do some clean up on this code? I believe It is more than just
moving the header files.

pll.h can probably be moved to include/linux/clk/ to avoid this. Would
like to hear from Mike on this before going ahead.
Anyway, instead of just commenting, I though I will be more useful and
went ahead and made some of the changes I have been talking about. I
fixed the multiple PLL definitions issue, the build infrastructure issue
and the commit ordering too.
I pushed the patches I fixed to devel-common-clk branch of my git tree.
It is build tested using davinci_all_defconfig but its not runtime tested.
Can you start from here and provide me incremental changes on top of
this? That way we can collaborate to finish this faster.
Thanks for offering some help. Yes I can provide you incremental patch.
But then could you also help me to squash/rebase and send patches to the
list for review?
Thanks,
Sekhar
