Hi Seth,

This patch adds the SMBus controller DeviceID for the Intel Panther Point PCH.

With each new chip, we have to add the SMBus device ID to pci_ids.h, then wait for Jesse to merge that, and only then I can apply the changes to i2c-i801.c. This approach slows things down needlessly.

It isn't mandatory to add IDs to pci_ids.h when an ID is only used locally in a device driver. So what I would like to propose is that we move all PCI_DEVICE_ID_INTEL_*_SMBUS declarations from pci_ids.h to i2c-i801.c now. Then you can resubmit your Panther Point patches, and the pci and i2c parts will be independent, so Jesse and myself don't depend on each other to apply them.

What do you think? Jesse, any objection?

Seth, if you agree, I can take care of the move, or you can send a patch doing that, whatever you prefer.

I've been thinking about this one myself, and I tend to agree. It'd probably be simpler if you went ahead and made the changes, and I'll be happy to review them.

Yeah, that makes sense. I'd be happy to take a patch to pull the defines out of pci_ids.h and push them into the x86 irq.c and your i2c code.

I really only had i2c in mind. For irq it's a little different because it relates to devices which are kind of generic and the IDs could be (and, I think, are) used in more than one place (such as quirks.c) for at least some of these devices.
