I'm not much of a fan of adding this. I know we added it for some of
the legacy platforms since moving over existing in-tree code would take
a while. But the thought was that new drivers wouldn't use it much.

Is the need for this now due to said drivers never been ported over, and now
also being used by Davinci? Or are new drivers added that rely on platform
data?

We are not fans of adding it either, and have been avoiding it up until
now.  You can rest assured that new additions here will be heavily
scrutinized.

The problem isn't new drivers, but old drivers that haven't grown DT
equivalents.

There are a handful of drivers/media drivers currently used by Davinci
via board files (and pdata) that still do not have DT mechanisms for
all the things used in pdata.

In attempting DT support for video on DaVinci, attempts were made (by
me[1]) to pass the data via DT, which triggered discussions among
linux-media maintainers about the "right way" of handling it.
Unfortunately, these discussions never fully materialized in an
short-term solution, so we were left with pdata for now.

I've offered to be the first to beta test the new DT mechanisms they
come up with, so when that happens, we'll gladly get rid of these pdata
quirks.

Great, that's the argument I was hoping to see for including this.
I.e. if we need this to use with legacy drivers then I'm alright with
it. If it had been used for new drivers I'd been worried.

I'll merge this next time I'm on the right machine for that.
