-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.
