qat_4xxx devices can be configured to allow either crypto or compression
operations. By default, devices are configured statically according
to following rule:
  - odd numbered devices assigned to compression services
  - even numbered devices assigned to crypto services

This set exposes two attributes in sysfs that allow to report and change
the state and the configuration of a QAT 4xxx device.
The first, /sys/bus/pci/devices/<BDF>/qat/state, allows to bring a
device down in order to change the configuration, and bring it up again.
The second, /sys/bus/pci/devices/<BDF>/qat/cfg_services, allows to
inspect the current configuration of a device (i.e. crypto or
compression) and change it.

Giovanni Cabiddu (4):
  crypto: qat - expose device state through sysfs for 4xxx
  crypto: qat - change behaviour of adf_cfg_add_key_value_param()
  crypto: qat - relocate and rename adf_sriov_prepare_restart()
  crypto: qat - expose device config through sysfs for 4xxx
