Merge tag 'rproc-v4.11' of git://github.com/andersson/remoteproc

Pull remoteproc updates from Bjorn Andersson:
 "This introduces support for booting the dedicated sensor core in the
  Qualcomm MSM8996, updates the Qualcomm ADSP and Hexagon drivers to
  utilize SMD subdevice helpers for properly handle shutdowns and
  restarts of the remoteproc, add virtio support to the ST remoteproc
  and refactor the Qualcomm Hexagon driver to handle variations between
  platforms.

  The support code for parsing, loading and authenticating Qualcomm
  firmware files (MDT) is refactored and move to drivers/soc/qcom, to
  allow for non-remoteproc drivers to utilize this.

  Finally it brings some cleanups to the remoteproc core"
