Because when I probe the SSI node, I want to know what the attached codec is.
So if anything, I would need a pointer from the SSI bus *to* the respective
child on the I2C bus.
I know little about platform devices/drivers, so I don't know how to use them.
Currently, I have a design flaw in my driver in that if I have two SSIs, and
each one is attached to a CS4270, I don't have any way of making sure that the
right CS4270 is using the right I2C address. I'm guessing that if I switch to
a platform-based model, I can resolve this issue. But for now, the CS4270
doesn't support that, so that patchset I have submitted works with what I
have. After my patchset has been applied, I'll be more than happy to look
into updating the CS4270 (and everything else) to use the platform model for I2C.
