Merge tag 'rproc-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux

Pull remoteproc updates from Bjorn Andersson:
 "In the remoteproc core, it's now possible to mark the sysfs attributes
  read only on a per-instance basis, which is then used by the TI wkup
  M3 driver.

  Also, the rproc_shutdown() interface propagates errors to the caller
  and an array underflow is fixed in the debugfs interface. The
  rproc_da_to_va() API is moved to the public API to allow e.g. child
  rpmsg devices to acquire pointers to memory shared with the remote
  processor.

  The TI K3 R5F and DSP drivers gains support for attaching to instances
  already started by the bootloader, aka IPC-only mode.

  The Mediatek remoteproc driver gains support for the MT8186 SCP. The
  driver's probe function is reordered and moved to use the devres
  version of rproc_alloc() to save a few gotos. The driver's probe
  function is also transitioned to use dev_err_probe() to provide better
  debug support.

  Support for the Qualcomm SC7280 Wireless Subsystem (WPSS) is
  introduced. The Hexagon based remoteproc drivers gains support for
  voting for interconnect bandwidth during launch of the remote
  processor. The modem subsystem (MSS) driver gains support for probing
  the BAM-DMUX driver, which provides the network interface towards the
  modem on a set of older Qualcomm platforms. In addition a number a bug
  fixes are introduces in the Qualcomm drivers.

  Lastly Qualcomm ADSP DeviceTree binding is converted to YAML format,
  to allow validation of DeviceTree source files"
