1 Qualcomm Remote File System Memory binding
3 This binding describes the Qualcomm remote filesystem memory, which serves the
4 purpose of describing the shared memory region used for remote processors to
7 - compatible:
11 		    "qcom,rmtfs-mem"
13 - reg:
15 	Value type: <prop-encoded-array>
16 	Definition: must specify base address and size of the memory region,
17 		    as described in reserved-memory.txt
19 - size:
21 	Value type: <prop-encoded-array>
22 	Definition: must specify a size of the memory region, as described in
23 		    reserved-memory.txt
25 - qcom,client-id:
28 	Definition: identifier of the client to use this region for buffers.
30 - qcom,vmid:
33 	Definition: vmid of the remote processor, to set up memory protection.
36 The following example shows the remote filesystem memory setup for APQ8016,
37 with the rmtfs region for the Hexagon DSP (id #1) located at 0x86700000.

40 		#address-cells = <2>;
41 		#size-cells = <2>;
45 			compatible = "qcom,rmtfs-mem";
47 			no-map;
49 			qcom,client-id = <1>;
