-Qualcomm Remote File System Memory binding
-
-This binding describes the Qualcomm remote filesystem memory, which serves the
-purpose of describing the shared memory region used for remote processors to
-access block device data using the Remote Filesystem protocol.
-
-- compatible:
-	Usage: required
-	Value type: <stringlist>
-	Definition: must be:
-		    "qcom,rmtfs-mem"
-
-- reg:
-	Usage: required for static allocation
-	Value type: <prop-encoded-array>
-	Definition: must specify base address and size of the memory region,
-		    as described in reserved-memory.txt
-
-- size:
-	Usage: required for dynamic allocation
-	Value type: <prop-encoded-array>
-	Definition: must specify a size of the memory region, as described in
-		    reserved-memory.txt
-
-- qcom,client-id:
-	Usage: required
-	Value type: <u32>
-	Definition: identifier of the client to use this region for buffers.
-
-- qcom,vmid:
-	Usage: optional
-	Value type: <u32>
-	Definition: vmid of the remote processor, to set up memory protection.
-
-= EXAMPLE
-The following example shows the remote filesystem memory setup for APQ8016,
-with the rmtfs region for the Hexagon DSP (id #1) located at 0x86700000.
-
-	reserved-memory {
-		#address-cells = <2>;
-		#size-cells = <2>;
-		ranges;
-
-		rmtfs@86700000 {
-			compatible = "qcom,rmtfs-mem";
-			reg = <0x0 0x86700000 0x0 0xe0000>;
-			no-map;
-
-			qcom,client-id = <1>;
-		};
