This patch moves the pca953x.h header from include/linux/i2c to
include/linux/platform_data and updates existing support accordingly.

Why does the GPIO driver need platform data from the
I2C driver???
Can't this just be made to go away?

I didn't dig that much in the driver, but I cannot imagine
another way to pass, for instance, the setup callback.
What would be a good alternative for you?

Hm so this is some combined platform data for I2C *and* GPIO?
Hmm ugly, but OK then.

I think the confusion here is because the pca953x.h header was initially
placed in linux/i2c.
This device is an I2C connected GPIO expander. The pca953x.h header has
the information needed for the platform to hook up to the device. It doesn't
really expose the fact that it's an I2C driver.
Just by 2 cents...

As this patch mainly touches arch/arm/*, Olof/Kevin, would you mind
applying it?

Looks like i2c or gpio maintainers should be taking it, but since Linus acked
it instead of applied it, I guess we can take it. :)
I'll apply it to next/cleanup for 3.12 if you resend me the patch with the
acks. Thanks!

Thanks a lot Olof, I worried about all the hunks hitting the arch/arm/*
hierarchy, and not much is happening in drivers/gpio this cycle
so think it is better off in ARM SoC.
