| WM8962 audio CODEC |
| |
| This device supports I2C only. |
| |
| Required properties: |
| |
| - compatible : "wlf,wm8962" |
| |
| - reg : the I2C address of the device. |
| |
| Optional properties: |
| - spk-mono: This is a boolean property. If present, the SPK_MONO bit |
| of R51 (Class D Control 2) gets set, indicating that the speaker is |
| in mono mode. |
| |
| - mic-cfg : Default register value for R48 (Additional Control 4). |
| If absent, the default should be the register default. |
| |
| - gpio-cfg : A list of GPIO configuration register values. The list must |
| be 6 entries long. If absent, no configuration of these registers is |
| performed. And note that only the value within [0x0, 0xffff] is valid. |
| Any other value is regarded as setting the GPIO register by its reset |
| value 0x0. |
| |
| Example: |
| |
| wm8962: codec@1a { |
| compatible = "wlf,wm8962"; |
| reg = <0x1a>; |
| |
| gpio-cfg = < |
| 0x0000 /* 0:Default */ |
| 0x0000 /* 1:Default */ |
| 0x0013 /* 2:FN_DMICCLK */ |
| 0x0000 /* 3:Default */ |
| 0x8014 /* 4:FN_DMICCDAT */ |
| 0x0000 /* 5:Default */ |
