Merge tag 'rproc-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux

Pull remoteproc updates from Bjorn Andersson:

 - Add i.MX94 support to the i.MX remoteproc driver, covering the
   Cortex-M7 and Cortex-M33 Sync cores. This also fixes programming of
   non-zero System Manager CPU/LMM reset vectors.

 - Move the remoteproc resource table definitions to a separate header,
   so they can be used by clients that do not otherwise depend on
   remoteproc. Switch the firmware resource handling over to the common
   iterator.

 - Update the Xilinx R5F remoteproc driver to check the remote core
   state before attaching, drop a binding header dependency, and add
   firmware-name based auto boot support.

 - Add Qualcomm Hawi ADSP/CDSP bindings, together with Shikra RPM
   bindings and CDSP, LPAICP, and MPSS PAS support. Fix a Qualcomm
   minidump leak, clean up PAS and WCSS reset handling, and make the
   user-visible Qualcomm naming consistent.

 - Remove a duplicate STM32_RPROC Kconfig dependency and make i.MX
   remoteproc instances use the device node name so multiple processors
   can be distinguished in sysfs.
