Grant,
Thanks for your Review comments.
Currently we have four hwmod data files:
2420, 2430 , 3xxx, 44xx
We need to fill these four files with hw info data to be passed
to driver there could be small info that might be duplicated.
Currently we are updating all the four files.
As Paul said there might be some changes done going forward.
To handle the hwmod files.
Hope this clarifies.
