SubjectRe: [PATCH 4/8] mfd: lpc_ich: Add support for iTCO v3
> Some newer Atom CPUs, eg Avoton and Bay Trail, use slightly different
> register layouts for the iTCO than the current v1 and v2 iTCO.
> Differences from previous iTCO versions include:
> - The ACPI space is enabled in the "ACPI base address" register instead
> of the "ACPI control register"
>
> - The "no reboot" functionality is set in the "Power Management
> Configuration" register instead of the "General Control and Status"
> (GCS) register or PCI configuration space.
>
> - The "ACPI Control Register" is not present on v3. The "Power
> Management Configuration Base Address" register resides at the same
> address is Avoton/Bay Trail.
>
> To differentiate these newer chipsets create a new v3 iTCO version and
> update the MFD driver to support them.
