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. Signed-off-by:

D0i3 adds additional interrupt reason bit, therefore we add a variable intr_source to save the interrupt causes for further dispatching. The interrupt cause is saved in the irq quick handler to achieve unified behavior for both MSI enabled and shared interrupt platforms. Signed-off-by:

The current power gating naming was confusing, we wish to swap meanings of register and flow level power gating terms, For registers writing level use terms set and unset: mei_me_pg_set, mei_me_pg_unset For flow/high level use power gating enter and power gating exit terms mei_me_pg_enter_sync, mei_me_pg_exit_sync Signed-off-by:

After commit b2b49ccb (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to depend on CONFIG_PM. Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere under drivers/misc/. Signed-off-by:

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:

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.

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:
