Kernel-4.18.0-80.el8_wm8962

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 */
>;
