Subject: [PATCH] rpmsg: core: make rpmsg bus DMA capable
Date: Fri, 30 Nov 2018 11:20:49 +0000	[thread overview]
Message-ID: <20181130112049.14444-1-srinivas.kandagatla@linaro.org> (raw)

Many of the rpmsg clients like audio, fastrpc drivers need to allocate
dma memory. Make this bus DMA capable so that the child devices can
use dma apis.
