Merge series "ASoC: wm8962: Conversion to json-schema and fix" from Geert Uytterhoeven <geert+renesas@glider.be>:

-
-This device supports I2C only.
-
-Required properties:
-
- - compatible : "wlf,wm8962"
-
- - reg : the I2C address of the device.
-
-Optional properties:
-
- - clocks : The clock source of the mclk
-
- - 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";
