Subject: [PATCH 09/10] crypto: ccp - Enable DMA service on a v5 CCP
Date: Tue, 26 Jul 2016 19:10:40 -0500	[thread overview]
Message-ID: <20160727001040.24944.93400.stgit@taos> (raw)
In-Reply-To: <20160727000652.24944.44919.stgit@taos>

Every CCP is capable of providing general DMA services.
Register the device as a provider.
