1 | WM8962 audio CODEC |
| 2 | ||
| 3 | This device supports I2C only. | |
| 4 | ||
| 5 | Required properties: | |
| 6 | ||
| 7 | - compatible : "wlf,wm8962" | |
| 8 | ||
| 9 | - reg : the I2C address of the device. | |

11 | Optional properties: |
| 12 | - spk-mono: This is a boolean property. If present, the SPK_MONO bit | |
| 13 | of R51 (Class D Control 2) gets set, indicating that the speaker is | |
| 14 | in mono mode. | |
| 15 | ||
| 16 | - mic-cfg : Default register value for R48 (Additional Control 4). | |
| 17 | If absent, the default should be the register default. | |
| 18 | ||
| 19 | - gpio-cfg : A list of GPIO configuration register values. The list must | |
| 20 | be 6 entries long. If absent, no configuration of these registers is | |
| 21 | performed. And note that only the value within [0x0, 0xffff] is valid. | |
| 22 | Any other value is regarded as setting the GPIO register by its reset | |
| 23 | value 0x0. | |
