Merge tag 'rpmsg-v4.9' of git://github.com/andersson/remoteproc
Pull rpmsg updates from Bjorn Andersson: "The bulk of these patches involve splitting the rpmsg implementation into a framework/API part and a virtio specific backend part. It then adds the Qualcomm Shared Memory Device (SMD) as an additional supported wire format. Also included is a set of code style cleanups that have been lingering for a while" * tag 'rpmsg-v4.9' of git://github.com/andersson/remoteproc: (26 commits) rpmsg: smd: fix dependency on QCOM_SMD=n rpmsg: Introduce Qualcomm SMD backend rpmsg: Allow callback to return errors rpmsg: Move virtio specifics from public header rpmsg: virtio: Hide vrp pointer from the public API rpmsg: Hide rpmsg indirection tables rpmsg: Split rpmsg core and virtio backend rpmsg: Split off generic tail of create_channel() rpmsg: Move helper for finding rpmsg devices to core rpmsg: Move endpoint related interface to rpmsg core rpmsg: Indirection table for rpmsg_endpoint operations rpmsg: Move rpmsg_device API to new file rpmsg: Introduce indirection table for rpmsg_device operations rpmsg: Clean up rpmsg device vs channel naming rpmsg: Make rpmsg_create_ept() take channel_info struct rpmsg: rpmsg_send() operations takes rpmsg_endpoint rpmsg: Name rpmsg devices based on channel id rpmsg: Enable matching devices with drivers based on DT rpmsg: Drop prototypes for non-existing functions samples/rpmsg: add support for multiple instances ...
