Re: [PATCH] MX2x: Add CSI platform device and resources.

This patch was sent mainly to initiate a discussion on how to consider
data acquisition device in i.MX2x platforms.

AFAIK, in both i.MX21 and i.MX27 there is a CSI HW module and a PrP HW
module. While they can be used on its own, with a direct communication
to the AHB bus, we could think of separating both modules in two
different devices, the patch I sent before would apply in this case
for CSI.

However, we could also think of both HW devices as a video acquisition
chain, because it doesn't makes sense in V4L2 model using the PrP
module on its own. Thus a "capture" device which enclosed both CSI and
PrP would make more sense.

What do you think?
