The PRCM and MPUSS parts of DRA7 devices are quite identical
to OMAP5 so as to reuse all the existing infrastructure around it.
Makefile updates to do just that.

are these in sync with DRA7 support being introduced for clock data in [1]?

I don't want to have a dependency on those patches since I am not sure of them
making it into 3.12.

Then we have to undo these changes again in clock data support. the chip 
wont bootup anyways without clock data information, so why not try and 
keep the changes that Tero is doing independent of these changes?

I still have something with clock data information which boots which I am maintaining out of tree till the clock movement to DT is sorted out.
Maybe what you are suggesting is quite trivial and I am unable to understand. Are you suggesting we do no compile $(clock-common) and the
dpll files for DRA7? Is that what you are worried we might have to revert?

yes - lets just drop that change. that allows what ever alignment we 
have for clock data/driver to handle it appropriately. IMHO, could also 
keeps your series independent from Tero's series.
