The ICH WDT can't be treated as a regular PCI * device as it's actually an integrated function of the ICH LPC interface * bridge. Detection is also awkward, because we can only infer the * presence of the watchdog timer from the fact that the machine has an * ICH chipset, or, on ACPI 2.x systems, by the presence of the 'WDDT' * ACPI table (although this driver does not support the ACPI detection * method). * * There is one slight problem on non-ACPI or ACPI 1.x systems: we have no * way of knowing if the WDT is permanently disabled (either by the BIOS * or in hardware). * * The WDT is programmed through I/O registers in the ACPI I/O space. * Intel swears it's always at offset 0x60, so we use that. * * For details about the ICH WDT, see Intel Application Note AP-725 * (document no. 292273-001). The WDT is also described in the individual * chipset datasheets, e.g. Intel82801EB ICH5 / 82801ER ICH5R Datasheet * (document no. 252516-001) sections 9.10 and 9.11. * * ICH6/7/8 support by Takeharu
