Merge tag 'rproc-v7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux

Pull remoteproc updates from Bjorn Andersson:
 "Add a remoteproc driver and binding for AMD MicroBlaze/V soft cores
  executing from dual-port BRAM, with clock and reset control and
  support for firmware without a resource table.

  Introduce a generic Qualcomm PAS service with SCM and OP-TEE backends,
  and migrate the PAS, MSS, and WCNSS remoteproc drivers to it. Add Nord
  ADSP and CDSP support, Eliza CDSP support, Maili ADSP/CDSP bindings,
  and late-attach SoCCP support for Kaanapali, Hawi, Maili, and Glymur.
  Enable BAM-DMUX child devices for PAS modems and fix PAS memory
  protection, handover, shutdown, and resource lifetime handling.

  Harden remoteproc lifecycle handling by attaching asynchronously,
  stopping crashed processors, synchronizing crash work with removal,
  and forcing shutdown before device resources are released. Reallocate
  resources during attach recovery and fix several reference and
  error-path leaks.

  Add Xilinx R5 crash detection and move RPU start and stop sequencing
  into the platform firmware driver. Consolidate write-combining
  carveout mapping callbacks, use correct I/O-memory accessors, and
  share optional ELF resource-table handling across drivers.

  Convert the TI Wakeup M3 binding to DT schema, correct Qualcomm and
  generic remoteproc bindings, and harden resource-table iteration
  against signed-offset out-of-bounds accesses"

+  Memory Architecture:
+
+    The dual-port BRAM allows simultaneous access from both processors:
+      - Port A: Connected to the host AXI BRAM controller for firmware loading
+      - Port B: Connected to the soft-core local memory bus for execution
+
+  The reg property describes the executable BRAM window in the processor-local
+  address space. The parent bus node translates that window to the system
+  physical address space by using standard devicetree address translation
+  through ranges. A clock input and a reset GPIO control the subsystem.

-TI Wakeup M3 Remoteproc Driver
-==============================
-
-The TI AM33xx and AM43xx family of devices use a small Cortex M3 co-processor
-(commonly referred to as Wakeup M3 or CM3) to help with various low power tasks
-that cannot be controlled from the MPU. This CM3 processor requires a firmware
-binary to accomplish this. The wkup_m3 remoteproc driver handles the loading of
-the firmware and booting of the CM3.
-
-Wkup M3 Device Node:
-====================
-A wkup_m3 device node is used to represent the Wakeup M3 processor instance
-within the SoC. It is added as a child node of the parent interconnect bus
-(l4_wkup) through which it is accessible to the MPU.
-
-Required properties:
---------------------
-- compatible:		Should be one of,
-				"ti,am3352-wkup-m3" for AM33xx SoCs
-				"ti,am4372-wkup-m3" for AM43xx SoCs
-- reg:			Should contain the address ranges for the two internal
-			memory regions, UMEM and DMEM. The parent node should
-			provide an appropriate ranges property for properly
-			translating these into bus addresses.
-- reg-names:		Contains the corresponding names for the two memory
-			regions. These should be named "umem" & "dmem".
-- ti,hwmods:		Name of the hwmod associated with the wkupm3 device.
-- ti,pm-firmware:	Name of firmware file to be used for loading and
-			booting the wkup_m3 remote processor.
-
-Example:
---------
-/* AM33xx */
-ocp {
-	 l4_wkup: l4_wkup@44c00000 {
-		compatible = "am335-l4-wkup", "simple-bus";
-		ranges = <0 0x44c00000 0x400000>;
-		#address-cells = <1>;
-		#size-cells = <1>;
-
-		wkup_m3: wkup_m3@100000 {
-			compatible = "ti,am3352-wkup-m3";
-			reg = <0x100000 0x4000>,
-			      <0x180000 0x2000>;
-			reg-names = "umem", "dmem";
-			ti,hwmods = "wkup_m3";
-			ti,pm-firmware = "am335x-pm-firmware.elf";
