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.
10	
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.
24	
25	Example:
26	
27	codec: 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 */
