Subject: [PATCH 2/2] crypto: hisilicon/zip - add hashjoin, gather, and UDMA data move features
From: Zhushuai Yin <yinzhushuai@...wei.com>
The new version of the hisilicon zip driver supports the hash join
and gather features, as well as the data move feature (UDMA),
including data copying and memory initialization functions.These
features are registered to the uacce subsystem.
