commit 9ff2007bea1f1bfc53ac0bc7ccf8200bb275fd52 upstream. Add MEI Lewisburg PCH IDs for Purley based workstations. Signed-off-by: Alexander Usyskin <alexander.usyskin@intel.com> Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2016-09-27mei: stop the stall timer worker if not neededAlexander Usyskin
The stall timer worker checks periodically if there is a stalled i/o transaction. The issue with the current implementation is that the timer is ticking also when there is no pending i/o transaction. This patch provides a simple change that prevents rescheduling of the delayed work when there is no pending i/o.

2016-01-08PM / Domains: add setter for dev.pm_domainTomeu Vizoso
Adds a function that sets the pointer to dev_pm_domain in struct device and that warns if the device has already finished probing. The reason why we want to enforce that is because in the general case that can cause problems and also that we can simplify code quite a bit if we can always assume that. This patch also changes all current code that directly sets the dev.pm_domain pointer.

2014-07-18mei: don't schedule suspend in pm idleAlexander Usyskin
Calling pm_schedule_suspend from the runtime pm idle callback may reschedule existing timer, thus in case of frequent runtime rpm idle call the suspend maybe starved. Instead we call pm_runtime_autosuspend which is checking if the timer is already charged. An example is monitoring device pci config space. Pci config sysfs handlers calls pci_config_pm_runtime_put/get helpers which in turns calls to device idle callback Cc: stable@vger.kernel.org # 3.15+ Signed-off-by: Alexander Usyskin <alexander.usyskin@intel.com> Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

NM and SPS FW types that may run on ME device on server platforms do not have valid MEI/HECI interface and driver should not be bound to it as this might lead to system hung. In practice not all BIOSes effectively hide such devices from the OS and in some cases it is not possible. We determine FW type by examining Host FW status registers in order to unbind the driver.
