This patch set consist of following updates:
1. Add misc workqueue for general purpose usage.
2. Move error source related CSRs from 4xxx to the wider GEN4 header
file.
3. Add support for HW QAT Power Management (PM) feature.
	This feature is enabled at init time (1) by sending an admin
message to
	the firmware, targeting the admin AE, that sets the idle time
before
	the device changes state and (2) by unmasking the PM source of
	interrupt in ERRMSK2.

	The interrupt handler is extended to handle a PM interrupt which
	is triggered by HW when a PM transition occurs. In this case,
the
	driver responds acknowledging the transaction using the HOST_MSG
	mailbox.


Wojciech Ziemba (3):
  crypto: qat - add misc workqueue
  crypto: qat - move and rename GEN4 error register definitions
  crypto: qat - enable power management for QAT GEN4
