+Xilinx ARM Cortex A53-R5 remoteproc driver
+==========================================
+
+ZynqMP family of devices use two Cortex R5 processors to help with various
+low power / real time tasks.
+
+This driver requires specific ZynqMP hardware design.
+
+ZynqMP R5 Device Node:
+=================================
+A ZynqMP R5 device node is used to represent RPU domain
+within ZynqMP SoC. This device node contains RPU processor
+subnodes.
+
+Required Properties:
+--------------------
+ - compatible : Should be "xlnx,zynqmp-r5-remoteproc-1.0"
+ - core_conf : R5 core configuration (valid string - split or lock-step)
+ - interrupts : Interrupt mapping for remoteproc IPI. It is required if the
+                user uses the remoteproc driver with the RPMsg kernel driver.
+ - interrupt-parent : Phandle for the interrupt controller. It is required if
+                      the user uses the remoteproc driver with the RPMsg kernel
+                      kernel driver.
+
+ZynqMP R5 Remoteproc Device Node:
+=================================
+A ZynqMP R5 Remoteproc device node is used to represent a RPU processor.
+It is a subnode to the ZynqMP R5 device node. It also contains tightly
+coupled memory subnodes.
+
+Required Properties:
+--------------------
+ - pnode-id:	ZynqMP R5 processor power domain ID which will be used by
+		ZynqMP power management unit to idetify the processor.
+
+Optional Properties:
+--------------------
+ - memory-region: reserved memory which will be used by R5 processor

+
+ZynqMP R5 TCM Device Node:
+=================================
+The ZynqMP R5 TCM device node is used to represent the TCM memory.
+It is a subnode to the ZynqMP R5 processor.
+
+Required Properties:
+--------------------
+ - reg:		TCM address range
+ - pnode-id:	TCM power domain ID
