Merge tag 'rpmsg-v7.4' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux
Pull rpmsg updates from Bjorn Andersson:
- Allow virtio rpmsg to use separate transmit and receive buffer counts
based on the vring sizes, and obtain buffer sizes from virtio config
space when the feature is negotiated. Document the configuration and
report the MTU in the sample driver.
- Fix signal interruption and timeout handling while waiting for a
virtio transmit buffer. Release the device tree node reference on
MediaTek channel teardown.
- Convert the rpmsg control ioctl comments to kernel-doc format.
