| 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; |
| }; |
| |
| * MSM8226 ASoC Machine driver |
| |
| Required properties: |
| - compatible : "qcom,msm8226-audio-tapan" |
| - qcom,model : The user-visible name of this sound card. |
| - qcom,tapan-mclk-clk-freq : Tapan mclk Freq in Hz. currently only 9600000Hz |
| is supported. |
| - qcom,prim-auxpcm-gpio-clk : GPIO on which Primary AUXPCM clk signal is coming. |
| - qcom,prim-auxpcm-gpio-sync : GPIO on which Primary AUXPCM SYNC signal is coming. |
| - qcom,prim-auxpcm-gpio-din : GPIO on which Primary AUXPCM DIN signal is coming. |
| - qcom,prim-auxpcm-gpio-dout : GPIO on which Primary AUXPCM DOUT signal is coming. |
| - qcom,prim-auxpcm-gpio-set : set of GPIO lines used for Primary AUXPCM port |
| Possible Values: |
| prim-gpio-prim : Primary AUXPCM shares GPIOs with Primary MI2S |
| prim-gpio-tert : Primary AUXPCM shares GPIOs with Tertiary MI2S |
| |
| Optional Properties: |
| - qcom,cdc-us-euro-gpios : GPIO on which gnd/mic swap signal is coming. |
| - qcom,cdc-lineout-spkr-gpios : GPIO which controls external PAs to enable Lineout1/2 speaker |
| - qcom,cdc-vdd-spkr-gpios : GPIO which controls PA for VDD speaker |
| |
| Example: |
| |
| sound { |
| compatible = "qcom,msm8226-audio-tapan"; |
| qcom,model = "msm8226-tapan-snd-card"; |
| qcom,tapan-mclk-clk-freq = <9600000>; |
| qcom,prim-auxpcm-gpio-clk = <&msmgpio 63 0>; |
| qcom,prim-auxpcm-gpio-sync = <&msmgpio 64 0>; |
| qcom,prim-auxpcm-gpio-din = <&msmgpio 65 0>; |
| qcom,prim-auxpcm-gpio-dout = <&msmgpio 66 0>; |
| qcom,prim-auxpcm-gpio-set = "prim-gpio-prim"; |
| qcom,cdc-us-euro-gpios = <&msmgpio 69 0>; |
| qcom,cdc-lineout-spkr-gpios = <&pm8226_gpios 2 0>; |
| qcom,cdc-vdd-spkr-gpios = <&pm8226_gpios 3 0>; |
