platform/x86:intel/pmc: Disable ACPI PM Timer disabling on Sky and Kaby Lake
There have been multiple reports that the ACPI PM Timer disabling is causing Sky and Kaby Lake systems to hang on all suspend (s2idle, s3, hibernate) methods. Remove the acpi_pm_tmr_ctl_offset and acpi_pm_tmr_disable_bit settings from spt_reg_map to disable the ACPI PM Timer disabling on Sky and Kaby Lake to fix the hang on suspend. Fixes: e86c8186d03a ("platform/x86:intel/pmc: Enable the ACPI PM Timer to be turned off when suspended") Reported-by: Paul Menzel <pmenzel@molgen.mpg.de> Closes: https://lore.kernel.org/linux-pm/18784f62-91ff-4d88-9621-6c88eb0af2b5@molgen.mpg.de/ Reported-by: Todd Brandt <todd.e.brandt@intel.com> Closes: https://bugzilla.kernel.org/show_bug.cgi?id=219346 Cc: Marek Maslanka <mmaslanka@google.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Tested-by: Todd Brandt <todd.e.brandt@intel.com> Tested-by: Paul Menzel <pmenzel@molgen.mpg.de> # Dell XPS 13 9360/0596KF Acked-by: Rafael J.
