1WM8962 audio CODEC 2 3This device supports I2C only. 4 5Required properties: 6 7 - compatible : "wlf,wm8962" 8 9 - reg : the I2C address of the device. 10 11Optional 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. 24 25Example: 26 27codec: wm8962@1a { 28 compatible = "wlf,wm8962"; 29 reg = <0x1a>; 30 31 gpio-cfg = < 32 0x0000 /* 0:Default */ 33 0x0000 /* 1:Default */ 34 0x0013 /* 2:FN_DMICCLK */ 35 0x0000 /* 3:Default */ 36 0x8014 /* 4:FN_DMICCDAT */ 37 0x0000 /* 5:Default */ 38 >; 39}; 40
