Merge tag 'rproc-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux

Pull remoteproc updates from Bjorn Andersson:
 "This makes the remoteproc core rproc_class const.

  DeviceTree bindings for a few different Qualcomm remoteprocs are
  updated to remove a range of validation warnings/errors. The Qualcomm
  SMD binding marks qcom,ipc deprecated, in favor or the mailbox
  interface.

  The TI K3 R5 remoteproc driver is updated to ensure that cores are
  powered up in the appropriate order. The driver also see a couple of
  fixes related to cleanups in error paths during probe.

  The Mediatek remoteproc driver is extended to support the MT8188 SCP
  core 1. Support for varying DRAM and IPI shared buffer sizes are
  introduced. This together with a couple of bug fixes and improvements
  to the driver.

  Support for the AMD-Xilinx Versal and Versal-NET platforms are added.
  Coredump support and support for parsing TCM information from
  DeviceTree is added to the Xilinx R5F remoteproc driver"
