[PATCH 1/3] crypto: qat - add decompression service to telemetry

[Suman Kumar Chakraborty]

From: Vijay Sundar Selvamani <vijay.sundar.selvamani@intel.com>

QAT GEN6 devices offer decompression as an additional service.

Update the telemetry ring pair service interface to support monitoring
decompression operations.

[PATCH 2/3] crypto: qat - enable telemetry for GEN6 devices

[Suman Kumar Chakraborty]

From: Vijay Sundar Selvamani <vijay.sundar.selvamani@intel.com>

Enable telemetry for QAT GEN6 devices by defining the firmware data
structures layouts, implementing the counters parsing logic and setting
the required properties on the adf_tl_hw_data data structure.

As for QAT GEN4, telemetry counters are exposed via debugfs using the
interface described in Documentation/ABI/testing/debugfs-driver-qat_telemetry.
