* Rockchip rk817 codec

Required properties:

- compatible: "rockchip,rk817-codec"
- clocks: a list of phandle + clock-specifer pairs, one for each entry in clock-names.
- clock-names: should be "mclk".
- spk-ctl-gpios: spk mute enable/disable
- hp-ctl-gpios: hp mute enable/disable
- spk-mute-delay-ms: spk mute delay time
- hp-mute-delay-ms: hp mute delay time
- spk-volume: DAC L/R volume digital setting for Speaker
- hp-volume: DAC L/R volume digital setting for Headphone

  * DDAC L/R volume setting
  * 0db~-95db,0.375db/step,for example:
  * 0: 0dB
  * 10: -3.75dB
  * 125: -46dB
  * 255: -95dB
  *
- capture-volume: ADC L/R volume digital setting for Microphone
  *
  * DADC L/R volume setting

- mic-in-differential:
  Boolean. Indicate MIC input are differential, rather than single-ended.

  Boolean. Indicate pdmdata output is enable or disable.
- use-ext-amplifier:
  Boolean. Indicate use external amplifier or not.
- adc-for-loopback:
  Boolean. Indicate adc use for loopback or not.
- out-l2spk-r2hp:
  Boolean. Use route config for L to ClassD speaker out and R to HPR out

Example for rk817 codec:

	compatible = "rockchip,rk817";
	reg = <0x20>;
	interrupt-parent = <&gpio0>;
	interrupts = <7 IRQ_TYPE_LEVEL_LOW>;
	pinctrl-names = "default";
	pinctrl-0 = <&pmic_int>;
