Subject: [PATCH v2 01/17] rpmsg: Enable matching devices with drivers based on DT
Date: Thu,  1 Sep 2016 15:27:53 -0700
Message-ID: <1472768889-3906-2-git-send-email-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <1472768889-3906-1-git-send-email-bjorn.andersson@linaro.org>

Make it possible to match rpmsg devices based on device tree node, in
addition to the id table. In some of these cases the rpmsg driver would
not have a id_table, so make this optional.
