2021-11-10T17:05:11Z

Pull rpmsg updates from Bjorn Andersson: "For the GLINK implementation this adds support for splitting outgoing messages that are too large to fit in the fifo, it introduces the use of "read notifications", to avoid polling in the case where the outgoing fifo is full and a few bugs are squashed. The return value of rpmsg_create_ept() for when RPMSG is disabled is corrected to return a valid error, the Mediatek rpmsg driver is updated to match the DT binding and a couple of cleanups are done in the virtio rpmsg driver" * tag 'rpmsg-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: rpmsg: glink: Send READ_NOTIFY command in FIFO full case rpmsg: glink: Remove channel decouple from rpdev release rpmsg: glink: Remove the rpmsg dev in close_ack rpmsg: glink: Add TX_DATA_CONT command while sending rpmsg: virtio_rpmsg_bus: use dev_warn_ratelimited for msg with no recipient rpmsg: virtio: Remove unused including rpmsg: Change naming of mediatek rpmsg property rpmsg: Fix rpmsg_create_ept return when RPMSG config is not defined rpmsg: glink: Replace strncpy() with strscpy_pad()
