1 | Analog Devices ADAU1701 |
| 2 | ||
| 3 | Required properties: | |
| 4 | ||
| 5 | - compatible: Should contain "adi,adau1701" | |
| 6 | - reg: The i2c address. Value depends on the state of ADDR0 | |
| 7 | and ADDR1, as wired in hardware. | |
| 8 | ||
| 9 | Optional properties: | |
| 10 | ||
| 11 | - reset-gpio: A GPIO spec to define which pin is connected to the | |
| 12 | chip's !RESET pin. If specified, the driver will | |
| 13 | assert a hardware reset at probe time. | |
| 2352d4bf DM |
14 | - adi,pll-mode-gpios: An array of two GPIO specs to describe the GPIOs |
| 15 | the ADAU's PLL config pins are connected to. | |
| 16 | The state of the pins are set according to the | |
| 17 | configured clock divider on ASoC side before the | |
| 18 | firmware is loaded. | |
| 97d0a868 DM |
19 | - adi,pin-config: An array of 12 numerical values selecting one of the |
| 20 | pin configurations as described in the datasheet, | |
| 21 | table 53. Note that the value of this property has | |
| 22 | to be prefixed with '/bits/ 8'. | |

23 | - avdd-supply: Power supply for AVDD, providing 3.3V |
| 24 | - dvdd-supply: Power supply for DVDD, providing 3.3V | |
