| Qualcomm Technologies, Inc. FastRPC MDSP CMA Heap |
| |
| The MSM MDSPRPC memory device allocates CMA memory, for sharing memory |
| of FastRPC buffers to remote processor(MDSP). |
| |
| Required properties: |
| -compatible: Must be "qcom,msm-mdsprpc-mem-region" |
| -memory-region: A phandle that points to a memory heap where the |
| heap memory is allocated |
| |
| Example: |
| qcom,mdsprpc-mem { |
| compatible = "qcom,msm-mdsprpc-mem-region"; |
| memory-region = <&mdsp_mem>; |
| }; |
| |
| Ion Heap: |
| |
| Ion heap allows for sharing of buffers between different processors |
| and between user space and kernel space. |
| (see Documentation/devicetree/bindings/arm/msm/msm_ion.txt). |
| |
| Required properties for Ion heap: |
| - compatible : "qcom,msm-ion" |
