If, as you say above, 8xx i2c was already broken in 2.6 (even in arch/ppc), then I see no reason not to go to an of_device right away. > It is apparent why - so far only mpc885 is alive in arch/powerpc, and it > is not going to change soon for 8xx. Actually, I plan to do some arch/powerpc 8xx work over the next couple months, so hopefully it will change soon. :-) -Scott
