Actually, I thought about this stuff. But sp5100 watchdog is not a pci device in AMD chipset. In another word, it doesn't export a pci header to OS. At current, we use SMBus pci device id and vendor id to detect watchdog on the AMD chipset (Because AMD use SMBus device id and revsion to identify different chipset version). At the same time, SMbus has its own driver piix4_smbus. Looks like we don't have a pci header to enumerate the watchdog.
