Merge tag 'rproc-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux

Pull remoteproc updates from Bjorn Andersson:
 "The remoteproc repo is moved to a new path on git.kernel.org, to allow
  Mathieu push access to the branches.

  Support for the Mediatek MT8195 SCP was added, the related DeviceTree
  binding was converted to YAML and MT8192 SCP was documented as well.

  Amlogic Meson6, Meson8, Meson8b and Meson8m2 has an ARC core to aid in
  resuming the system after suspend, a new remoteproc driver for booting
  this core is introduced.

  A new driver to support the DSP processor found on NXP i.MX8QM,
  i.MX8QXP, i.MX8MP and i.MX8ULP is added.

  The Qualcomm modem and TrustZone based remoteproc drivers gains
  support for the modem in SC7280 and MSM8996 gains support for a
  missing power-domain.

  Throughout the Qualcomm drivers, the support for informing the
  always-on power coprocessor about the state of each remoteproc is
  reworked to avoid complications related to our use of genpd and the
  system suspend state.

  Lastly a number of small fixes are found throughout the drivers and
  framework"
