Subject: [PATCH 07/10] crypto/nx: Enable and setup GZIP compresstion type
Date: Sun, 15 Dec 2019 05:03:59 -0800 [thread overview]
Message-ID: <1576415039.16318.4091.camel@hbabu-laptop> (raw)
In-Reply-To: <1576414240.16318.4066.camel@hbabu-laptop>
Changes to probe GZIP device-tree nodes, open RX windows and setup
GZIP compression type. No plans to provide GZIP usage in kernel right
now, but this patch enables GZIP for user space usage.
