From 93bc3feee8bd5fbe29ad27779c5e7b369fd7c80b Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Wed, 22 Apr 2020 17:37:35 -0700 Subject: [PATCH] rpmsg: glink: Integrate glink_ssr in qcom_glink In all but the very special case of a system with _only_ glink_rpm, GLINK is dependent on glink_ssr, so move it to rpmsg and combine it with qcom_glink_native in the new qcom_glink kernel module.
