QCOM WCD9335 Codec Qualcomm WCD9335 Codec is a standalone Hi-Fi audio codec IC, supports Qualcomm Technologies, Inc. (QTI) multimedia solutions, including the MSM8996, MSM8976, and MSM8956 chipsets. It has in-built Soundwire controller, interrupt mux. It supports both I2S/I2C and SLIMbus audio interfaces. Required properties with SLIMbus Interface: - compatible: Usage: required Value type: Definition: For SLIMbus interface it should be "slimMID,PID", textual representation of Manufacturer ID, Product Code, shall be in lower case hexadecimal with leading zeroes suppressed. Refer to slimbus/bus.txt for details. Should be: "slim217,1a0" for MSM8996 and APQ8096 SoCs with SLIMbus. - reg Usage: required Value type: Definition: Should be ('Device index', 'Instance ID') - interrupts Usage: required Value type: Definition: Interrupts via WCD INTR1 and INTR2 pins - interrupt-names: Usage: required Value type: Definition: Interrupt names of WCD INTR1 and INTR2 Should be: "intr1", "intr2" - reset-gpios: Usage: required Value type: Definition: Reset gpio line - slim-ifc-dev: Usage: required Value type: Definition: SLIM interface device - clocks: Usage: required Value type: Definition: See clock-bindings.txt section "consumers". List of three clock specifiers for mclk, mclk2 and slimbus clock. - clock-names: Usage: required Value type: Definition: Must contain "mclk", "mclk2" and "slimbus" strings. - vdd-buck-supply: Usage: required Value type: Definition: Should contain a reference to the 1.8V buck supply - vdd-buck-sido-supply: Usage: required Value type: Definition: Should contain a reference to the 1.8V SIDO buck supply - vdd-rx-supply: Usage: required Value type: Definition: Should contain a reference to the 1.8V rx supply - vdd-tx-supply: Usage: required Value type: Definition: Should contain a reference to the 1.8V tx supply - vdd-vbat-supply: Usage: Optional Value type: Definition: Should contain a reference to the vbat supply - vdd-micbias-supply: Usage: required Value type: Definition: Should contain a reference to the micbias supply - vdd-io-supply: Usage: required Value type: Definition: Should contain a reference to the 1.8V io supply - interrupt-controller: Usage: required Definition: Indicating that this is a interrupt controller - #interrupt-cells: Usage: required Value type: Definition: should be 1 #sound-dai-cells Usage: required Value type: Definition: Must be 1 audio-codec@1{ compatible = "slim217,1a0"; reg = <1 0>; interrupts = <&msmgpio 54 IRQ_TYPE_LEVEL_HIGH>; interrupt-names = "intr2" reset-gpios = <&msmgpio 64 GPIO_ACTIVE_LOW>; slim-ifc-dev = <&wc9335_ifd>; clock-names = "mclk", "native"; clocks = <&rpmcc RPM_SMD_DIV_CLK1>, <&rpmcc RPM_SMD_BB_CLK1>; vdd-buck-supply = <&pm8994_s4>; vdd-rx-supply = <&pm8994_s4>; vdd-buck-sido-supply = <&pm8994_s4>; vdd-tx-supply = <&pm8994_s4>; vdd-io-supply = <&pm8994_s4>; #sound-dai-cells = <1>; }
