> ref: [1], we discussed that we should now be able to introduce all instances of h/w blocks into the dra7.dts. Further, considering [2]
hmm, thats a long discussion on crossbar driver that [1] points to. Do you want to summarize what you mean by 'introduce all instances of h/w blocks'
> would you not want to follow "status = disabled" for all modules by default and enable required modules in board file, so that we dont have to respin this yet again?
Well, I was just following the convention of whats already followed on existing OMAPs. See [3] for some views on these.
