NXP TFA9879 class-D audio amplifier

Required properties:

- compatible : "nxp,tfa9879"

- reg : the I2C address of the device

- #sound-dai-cells : must be 0.

Example:

&i2c1 {
	pinctrl-names = "default";
	pinctrl-0 = <&pinctrl_i2c1>;

	amp: amp@6c {
		#sound-dai-cells = <0>;
		compatible = "nxp,tfa9879";
		reg = <0x6c>;
	};
};
ASoC: tfa9879: Add device tree bindings Even though the tfa9879 driver can probe via device tree trough the I2C core code, it is preferable to have explicit device tree bindings instead [1], so add this support.

ASoC: tfa9879: clean up bindings Fix a couple of nitpicks: - list #sound-dai-cells as a required property. - The chip supports full speed I2C; don't indicate standard mode only. - status = "okay" is just noise. - The chip is an amplifier, not a codec. - consistently indent with tabs.
