Merge tag 'rpmsg' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull "remoteproc/rpmsg: new subsystem" from Arnd Bergmann: "This new subsystem provides a common way to talk to secondary processors on an SoC, e.g. a DSP, GPU or service processor, using virtio as the transport. In the long run, it should replace a few dozen vendor specific ways to do the same thing, which all never made it into the upstream kernel. There is a broad agreement that rpmsg is the way to go here and several vendors have started working on replacing their own subsystems. Two branches each add one virtio protocol number. Fortunately the numbers were agreed upon in advance, so there are only context changes. Signed-off-by: Arnd Bergmann <arnd@arndb.de>" Fixed up trivial protocol number conflict due to the mentioned additions next to each other. * tag 'rpmsg' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (32 commits) remoteproc: cleanup resource table parsing paths remoteproc: remove the hardcoded vring alignment remoteproc/omap: remove the mbox_callback limitation remoteproc: remove the single rpmsg vdev limitation remoteproc: safer boot/shutdown order remoteproc: remoteproc_rpmsg -> remoteproc_virtio remoteproc: resource table overhaul rpmsg: fix build warning when dma_addr_t is 64-bit rpmsg: fix published buffer length in rpmsg_recv_done rpmsg: validate incoming message length before propagating rpmsg: fix name service endpoint leak remoteproc/omap: two Kconfig fixes remoteproc: make sure we're parsing a 32bit firmware remoteproc: s/big switch/lookup table/ remoteproc: bail out if firmware has different endianess remoteproc: don't use virtio's weak barriers rpmsg: rename virtqueue_add_buf_gfp to virtqueue_add_buf rpmsg: depend on EXPERIMENTAL remoteproc: depend on EXPERIMENTAL rpmsg: add Kconfig menu ...
