1	Analog Devices ADAU1701
2	
3	Required properties:
4	
5	 - compatible:		Should contain "adi,adau1701"
6	 - reg:			The i2c address. Value depends on the state of ADDR0
7				and ADDR1, as wired in hardware.
8	
9	Optional properties:
10	
11	 - reset-gpio: 		A GPIO spec to define which pin is connected to the
12				chip's !RESET pin. If specified, the driver will
13				assert a hardware reset at probe time.
14	 - adi,pll-mode-gpios:	An array of two GPIO specs to describe the GPIOs
15				the ADAU's PLL config pins are connected to.
16				The state of the pins are set according to the
17				configured clock divider on ASoC side before the
18				firmware is loaded.
19	 - adi,pin-config:	An array of 12 numerical values selecting one of the
20				pin configurations as described in the datasheet,
21				table 53. Note that the value of this property has
22				to be prefixed with '/bits/ 8'.
23	
24	Examples:
25	
26		i2c_bus {
27			adau1701@34 {
28				compatible = "adi,adau1701";
29				reg = <0x34>;
30				reset-gpio = <&gpio 23 0>;
31				adi,pll-mode-gpios = <&gpio 24 0 &gpio 25 0>;
32				adi,pin-config = /bits/ 8 <0x4 0x7 0x5 0x5 0x4 0x4
33	                                                   0x4 0x4 0x4 0x4 0x4 0x4>;
34			};
