Hi again, Glad I managed to make sense. I checked the hardware spec on the board and it looks like we're using everything, apart from the SEC and maybe the stand-alone I2C (I think we're just using the one within the CMP). By the way, I made a mistake and the actual processor on the board is the cut-down 8541, not the 8555. My apologies for that.
This morning I added some printks and confirmed that there is no code behind pm_ops, so my question remains: is there some code out there that I can use? (hope so, otherwise I'm doomed...)

It does, what periphs are you using on the 8555 itself? - k _______________________________________________ Linuxppc-embedded mailing list [email protected] https://ozlabs.org/mailman/listinfo/linuxppc-embedded
