-------------------------+-----------------------------
AMD's common i2c controller (1022:790b) could be added to our i2c-piix4
driver with low/medium effort.
Linux handles AMD in via drivers/i2c/busses/i2c-piix4.c
(PCI_DEVICE_ID_AMD_KERNCZ_SMBUS).
We really need some quirk checks (mmio mostly), and to adjust addresses
slightly based on those quirk checks.
