| * msm-adsp-loader |
| |
| Required properties: |
| - compatible : "qcom,adsp-loader" |
| - qcom,adsp-state: |
| It is possible that some MSM use PIL to load the ADSP image. While |
| other MSM may use SBL to load the ADSP image at boot. Audio APR needs |
| state of ADSP to register and enable APR to be used for sending commands |
| to ADSP. so adsp-state represents the state of ADSP to ADSP loader. |
| Value of 0 indicates ADSP loader needs to use PIL and value of 2 means |
| ADSP image is already loaded by SBL. |
| |
| Example: |
| |
| qcom,msm-adsp-loader { |
| compatible = "qcom,adsp-loader"; |
| qcom,adsp-state = <2>; |
| }; |
| |
| * msm-audio-ion |
| |
| Required properties: |
| - compatible : "qcom,msm-audio-ion" |
| |
| Optional properties: |
| - qcom,smmu-enabled: |
| It is possible that some MSM have SMMU in ADSP. While other MSM use |
| no SMMU. Audio lib introduce wrapper for ION APIs. The wrapper needs |
| presence of SMMU in ADSP to handle ION APIs differently. |
| Presence of this property means ADSP has SMMU in it. |
| |
| Example: |
| |
| qcom,msm-audio-ion { |
| compatible = "qcom,msm-audio-ion; |
| qcom,smmu-enabled; |
| }; |
