| 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. |
