[PATCH 3/4] rpmsg: glink: Integrate glink_ssr in qcom_glink

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
