Subject: [PATCH 2/3] rpmsg: core: make rpmsg bus DMA capable
Date: Fri, 2 Mar 2018 14:55:30 +0000 [thread overview]
Message-ID: <20180302145531.20463-3-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20180302145531.20463-1-srinivas.kandagatla@linaro.org>
From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>
Many of the rpmsg clients like audio drivers need to allocate
dma memory. Make this bus DMA capable so that the child devices
can use dma apis.
