| * Freescale SGTL5000 Stereo Codec |
| |
| Required properties: |
| - compatible : "fsl,sgtl5000". |
| |
| - reg : the I2C address of the device |
| |
| - #sound-dai-cells: must be equal to 0 |
| |
| - clocks : the clock provider of SYS_MCLK |
| |
| - VDDA-supply : the regulator provider of VDDA |
| |
| - VDDIO-supply: the regulator provider of VDDIO |
| |
| Optional properties: |
| |
| - VDDD-supply : the regulator provider of VDDD |
| |
| - micbias-resistor-k-ohms : the bias resistor to be used in kOmhs |
| The resistor can take values of 2k, 4k or 8k. |
| If set to 0 it will be off. |
| If this node is not mentioned or if the value is unknown, then |
| micbias resistor is set to 4K. |
| |
| - micbias-voltage-m-volts : the bias voltage to be used in mVolts |
| The voltage can take values from 1.25V to 3V by 250mV steps |
| If this node is not mentioned or the value is unknown, then |
| the value is set to 1.25V. |
| |
| - lrclk-strength: the LRCLK pad strength. Possible values are: |
| 0, 1, 2 and 3 as per the table below: |
| |
| VDDIO 1.8V 2.5V 3.3V |
| 0 = Disable |
| 1 = 1.66 mA 2.87 mA 4.02 mA |
| 2 = 3.33 mA 5.74 mA 8.03 mA |
| 3 = 4.99 mA 8.61 mA 12.05 mA |
| |
| Example: |
| |
| sgtl5000: codec@a { |
| compatible = "fsl,sgtl5000"; |
| reg = <0x0a>; |
| #sound-dai-cells = <0>; |
| clocks = <&clks 150>; |
| micbias-resistor-k-ohms = <2>; |
| micbias-voltage-m-volts = <2250>; |
| VDDA-supply = <®_3p3v>; |
| VDDIO-supply = <®_3p3v>; |
| }; |
