Just so you know, I2C on the MPC5200 has been discussed a few times on the linuxppc-embedded list recently. My driver for MPC107/824x/85xx/52xx is in Greg KH's queue and should go to Linus sometime after 2.6.8 comes out. The MPC5200 requires further patches to add the correct OCP entries; Sylvain Munaut is preparing these. The driver does have some problems with interrupts on MPC5200, but I'm told it works correctly in polled mode. See the archive: http://lists.linuxppc.org/linuxppc-embedded/200407/msg00388.html and mail me if you want to see the tidied version. - Adrian Cox Humboldt Solutions Ltd.
