OK, but should it include *all* headers it needs? If so, then the existing
<linux/i2c-algo-8xx.h> should include both <asm/8xx_immap.h> and
<asm/commproc.h> since it uses the types "i2c8xx_t" and "cpm8xx_t".

Agreed.

I was referring to the discussion about the combined 8xx/8260 i2c driver
I posted. I agree - the above should stay on the list. Cheers!
