Date: Mon, 15 Aug 2016 17:17:07 -0700 From: Bjorn Andersson <bjorn.andersson@...aro.org> To: Ohad Ben-Cohen <ohad@...ery.com>, Bjorn Andersson <bjorn.andersson@...aro.org> Cc: linux-remoteproc@...r.kernel.org, linux-arm-msm@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org Subject: [PATCH 01/14] rpmsg: Enable matching devices with drivers based on DT 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.
