AK4104 S/PDIF transmitter

This device supports SPI mode only.

Required properties:

  - compatible : "asahi-kasei,ak4104"

  - reg : The chip select number on the SPI bus

Optional properties:

  - reset-gpio : a GPIO spec for the reset pin. If specified, it will be
		 deasserted before communication to the device starts.

Example:

spdif: ak4104@0 {
	compatible = "asahi-kasei,ak4104";
	reg = <0>;
	spi-max-frequency = <5000000>;
};

			`- compatible : "asahi-kasei,ak4104"`

			`- reg : The chip select number on the SPI bus`

ASoC: ak4104: add reset line property to DT bindings This device doesn't have a pdata definition for legacy boards, and unless anyone need to control the reset GPIO, it's not worth adding one. So this feature is only available to DT users for now.
