| 3 | These devices support both I2C and SPI (configured with pin strapping |
| 4 | on the board). |
| 5 | |
| 6 | Required properties: |
| 7 | |
| 8 | - compatible : "ti,pcm1862", |
| 9 | "ti,pcm1863", |
| 10 | "ti,pcm1864", |
| 11 | "ti,pcm1865" |
| 12 | |
| 13 | - reg : The I2C address of the device for I2C, the chip select |
| 14 | number for SPI. |
| 15 | |
| 16 | - avdd-supply: Analog core power supply (3.3v) |
| 17 | - dvdd-supply: Digital core power supply |
| 18 | - iovdd-supply: Digital IO power supply |

| 21 | CODEC input pins: |
| 22 | * VINL1 |
| 23 | * VINR1 |
| 24 | * VINL2 |
| 25 | * VINR2 |
| 26 | * VINL3 |
| 27 | * VINR3 |
| 28 | * VINL4 |
| 29 | * VINR4 |
| 30 | |
| 31 | The pins can be used in referring sound node's audio-routing property. |

| 33 | Example: |
| 34 | |
| 35 | pcm186x: audio-codec@4a { |
| 36 | compatible = "ti,pcm1865"; |
| 37 | reg = <0x4a>; |
| 38 | |
| 39 | avdd-supply = <®_3v3_analog>; |
| 40 | dvdd-supply = <®_3v3>; |
| 41 | iovdd-supply = <®_1v8>; |
| 42 | }; |
