Hi Peter, > 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 <ptyser@xxxxxxxxxxx> > Tested-by: Rajat Jain <rajatjain@xxxxxxxxxxx> > Cc: Guenter Roeck <linux@xxxxxxxxxxxx> > Cc: James Ralston <james.d.ralston@xxxxxxxxx> > Cc: Samuel Ortiz <sameo@xxxxxxxxxxxxxxx> > Cc: Lee Jones <lee.jones@xxxxxxxxxx> > Cc: Wim Van Sebroeck <wim@xxxxxxxxx> > Cc: linux-watchdog@xxxxxxxxxxxxxxx > --- > drivers/mfd/lpc_ich.c | 81 +++++++++++++++++++++++++++++++++++------- > include/linux/mfd/lpc_ich.h | 8 ++-- > 2 files changed, 71 insertions(+), 18 deletions(-) > Acked-by: Wim Van Sebroeck <wim@xxxxxxxxx> Kind regards, Wim. -- To unsubscribe from this list: send the line "unsubscribe linux-watchdog" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
