Subject: [PATCH 0/3] Add descriptor definitions for a few new DSA operations

A few new DSA operations are introduced [1]:
1. Memory fill with 16 bytes of pattern.
2. Translation fetch.
3. Data Integrity Extension (DIX) generate.

This series adds descriptor definitions for the new DSA operations.
With the definitions, user can issue the DSA operations to optimize
corresponding transactions.

Reference:
1. DSA 2.0 spec: https://software.intel.com/content/www/us/en/develop/articles/intel-data-streaming-accelerator-architecture-specification.html

Fenghua Yu (3):
  dmaengine: idxd: Add descriptor definitions for 16 bytes of pattern in
    memory fill operation
  dmaengine: idxd: Add descriptor definitions for DIX generate operation
  dmaengine: idxd: Add descriptor definitions for translation fetch
    operation
