> 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. > > Signed-off-by: Peter Tyser <[email protected]> > Tested-by: Rajat Jain <[email protected]> > Cc: Guenter Roeck <[email protected]> > Cc: James Ralston <[email protected]> > Cc: Samuel Ortiz <[email protected]> > Cc: Lee Jones <[email protected]> > Cc: Wim Van Sebroeck <[email protected]> > Cc: [email protected] > --- > drivers/mfd/lpc_ich.c | 81 +++++++++++++++++++++++++++++++++++------- > include/linux/mfd/lpc_ich.h | 8 ++-- > 2 files changed, 71 insertions(+), 18 deletions(-)
