* mei: me: clear interrupts on the resume pathTomas Winkler2013-06-131-0/+1
| | | | | | | | | | | | | | 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: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* | mei: rename function mei_hw_init to mei_startTomas Winkler2013-03-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | The hw initialization is now done as part of hw specific code this makes the name mei_hw_init little misleading. We rename it to mei_start in spirit of already existing functions mei_stop and mei_reset.

* | mei: unregister watchdog from mei_stop functionTomas Winkler2013-03-291-2/+0
| | | | | | | | | | | | | | | | we need to unregister watchdog device both in suspend and remove as the registration is recreated on reset Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* | mei: add mei_stop function to stop mei deviceTomas Winkler2013-03-151-45/+7
|/ | | | | | | | | | | | | 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: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
