The data + is stored in a shared memory region and is loaded by the remote processor. + + Some of the Qualcomm Technologies Inc SoC's have hardware accelerators for + controlling shared resources. Depending on the board configuration the shared + resource properties may change. These properties are dynamically probed by the + remote processor and made available in the shared memory. + +maintainers: + - Bjorn Andersson <bjorn.andersson@linaro.org> + +allOf: + - $ref: "reserved-memory.yaml" + +properties: + compatible: + const: qcom,cmd-db + +required: + - reg + +unevaluatedProperties: false + +examples: + - | + reserved-memory { + #address-cells = <1>; + #size-cells = <1>; + ranges; + + reserved-memory@85fe0000 { + reg = <0x85fe0000 0x20000>; + compatible = "qcom,cmd-db"; + no-map; + }; + }; |
