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