For non wakeable devices we can't use pci runtime framework as we are not able to wakeup from D3 states. Instead we create new pg runtime domain that only drives ME power gating protocol to reduce the power consumption. Signed-off-by:

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. In this patch we are adding check for ME on Cougar Point, Lynx Point Devices Cc: stable <stable@vger.kernel.org> # 3.10+ Signed-off-by:

None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

1. MEI_DEV_RESETTING device state spans only hardware reset flow while starting dev state is saved into a local variable for further reference, this let us to reduce big if statements in case we are trying to avoid nested resets 2. During initializations if the reset ended in MEI_DEV_DISABLED device state we bail out with -ENODEV 3. Remove redundant interrupts_enabled parameter as this can be deduced from the starting dev_state 4. mei_reset propagates error code to the caller 5. Add mei_restart function to wrap the pci resume Signed-off-by:

Cancel each work properly and remove flash_work_queue. Quoting documentation: In most situations flushing the entire workqueue is overkill; you merely need to know that a particular work item isn't queued and isn't running. In such cases you should use cancel_delayed_work_sync() or cancel_work_sync() instead. Signed-off-by:

We need to clear pending interrupts on the resume path. This brings the device into defined state before starting the reset flow This should solve suspend/resume issues: mei_me : wait hw ready failed. status = 0x0 mei_me : version message write failed Signed-off-by:

mei_stop calls mei_reset with disabling the interrupts. It will have the same effect as the open code it replaces in the mei_remove. The reset sequence on remove is required for the Lynx Point LP devices to clean the reset state. mei_stop is called from mei_pci_suspend and mei_remove functions Signed-off-by:
