| 2 | |
| 3 | This device supports I2C only. |
| 4 | |
| 5 | Required properties: |
| 6 | |
| 7 | - compatible : One of "realtek,rt5659" or "realtek,rt5658". |
| 8 | |
| 9 | - reg : The I2C address of the device. |
| 10 | |
| 11 | - interrupts : The CODEC's interrupt output. |
| 12 | |
| 13 | Optional properties: |
| 14 | |
| 15 | - clocks: The phandle of the master clock to the CODEC |
| 16 | - clock-names: Should be "mclk" |
| 17 | |
| 18 | - realtek,in1-differential |
| 19 | - realtek,in3-differential |
| 20 | - realtek,in4-differential |
| 21 | Boolean. Indicate MIC1/3/4 input are differential, rather than single-ended. |
| 22 | |
| 23 | - realtek,dmic1-data-pin |
| 24 | 0: dmic1 is not used |
| 25 | 1: using IN2N pin as dmic1 data pin |
| 26 | 2: using GPIO5 pin as dmic1 data pin |
| 27 | 3: using GPIO9 pin as dmic1 data pin |
| 28 | 4: using GPIO11 pin as dmic1 data pin |
| 29 | |
| 30 | - realtek,dmic2-data-pin |
| 31 | 0: dmic2 is not used |
| 32 | 1: using IN2P pin as dmic2 data pin |
| 33 | 2: using GPIO6 pin as dmic2 data pin |
| 34 | 3: using GPIO10 pin as dmic2 data pin |
| 35 | 4: using GPIO12 pin as dmic2 data pin |
| 36 | |
| 37 | - realtek,jd-src |
| 38 | 0: No JD is used |
| 39 | 1: using JD3 as JD source |
| 40 | 2: JD source for Intel HDA header |
| 41 | |
| 42 | - realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin. |
| 43 | - realtek,reset-gpios : The GPIO that controls the CODEC's RESET pin. |
| 44 | |
| 45 | - sound-name-prefix: Please refer to dai-common.yaml |
| 46 | |
| 47 | - ports: A Codec may have a single or multiple I2S interfaces. These |
| 48 | interfaces on Codec side can be described under 'ports' or 'port'. |
| 49 | When the SoC or host device is connected to multiple interfaces of |
| 50 | the Codec, the connectivity can be described using 'ports' property. |
| 51 | If a single interface is used, then 'port' can be used. The usage |
| 52 | depends on the platform or board design. |
| 53 | Please refer to Documentation/devicetree/bindings/graph.txt |
