Subject: [PATCH v3 09/15] rpmsg: smd: add sendto and trysendto ops
Date: Thu, 4 Feb 2021 09:45:28 +0100 [thread overview]
Message-ID: <20210204084534.10516-10-arnaud.pouliquen@foss.st.com> (raw)
In-Reply-To: <20210204084534.10516-1-arnaud.pouliquen@foss.st.com>
Implement the sendto ops to support the future rpmsg_char update for the
vitio backend support.
The use of sendto in rpmsg_char is needed as a destination address is
requested at least by the virtio backend.
The SMD implementation does not need a destination address so ignores it.
