Subject: [PATCH 08/13] dmaengine: edma: Do not allocate memory for edma_rsv_info in case of DT boot
Date: Wed, 14 Oct 2015 16:12:19 +0300 [thread overview]
Message-ID: <1444828344-21378-9-git-send-email-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <1444828344-21378-1-git-send-email-peter.ujfalusi@ti.com>
The channel/slot reservation is not supported when booted with DT so there
is not need to allocate memory.
