[RFC,2/8] davinci: vpfe: add IPIPE hardware layer support

Commit Message

From: Nagabhushana Netagunte <[e-mail]>

add dm365 IPIPE hardware support. IPIPE is the hardware IP which
implements the functionality required for resizer, previewer and
the associated feature support. This is built along with the vpfe
driver, and implements hardware setup including coeffcient
programming for various hardware filters, gamma, cfa and clock
enable.

Hi Manju,

Thanks for the RFC. I've reviewed it, and there are a few systematic issues
but nothing major. I'm not sure if the same also apply to other patches.
Notning really related to V4L2 yet.

- If function returns no meaningful value it should be void.
- Returning early may easily allow unindenting the res of the function.
- No need for extra parenthesis in assignments.
- Using a temporary variable do not always improve readability in register
  writes.

No need for parentheses in such cases and I don't think they improve
readability. Similar cases can be found throughout the patch.

The three above lines can be move out of the conditions, index to the array
is rsz_id.

And the three above lines may be removed.

Numerical index could be replaced by e.g. definition RSZ_A_IDX.

If the function can't fail it should have void return type.

Not really a comment to the patxh, but what are the meanings of bad and sad
above?
